-/* Subroutine SETUP is the only place where order is assigned a value, */
-/* and that value is 10. It could increase efficiency 1% or so to */
-/* declare order as a constant (i.e., a Fortran PARAMETER) instead of as
-*/
-/* a variable in a COMMON block, since it is used in many places in the */
-/* core of the coding and decoding routines. Actually, I take that back.
-*/
-/* At least when compiling with f2c, the upper bound of DO loops is */
-/* stored in a local variable before the DO loop begins, and then that is
-*/
-/* compared against on each iteration. */
-/* Similarly for lframe, which is given a value of MAXFRM in SETUP. */
-/* Similarly for quant, which is given a value of 2400 in SETUP. quant */
-/* is used in only a few places, and never in the core coding and */
-/* decoding routines, so it could be eliminated entirely. */
-/* nbits is similar to quant, and is given a value of 54 in SETUP. */
-/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
-/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
-/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
-*/
-/* a constant or a variable, since it is only examined once per frame. */
-/* Leaving it as a variable that is set to .TRUE. seems like a good */
-/* idea, since it does enable some error-correction capability for */
-/* unvoiced frames, with no change in the coding rate, and no noticeable
-*/
-/* quality difference in the decoded speech. */

-/* and remove ERROR and nunsfm completely. */
-/* iclip is initialized to 0 in SETUP, and incremented in entry SWRITE in

-/* a variable in a COMMON block, since it is used in many places in the */

-*/
-/* At least when compiling with f2c, the upper bound of DO loops is */

-/* compared against on each iteration. */
-/* Similarly for lframe, which is given a value of MAXFRM in SETUP. */
-/* Similarly for quant, which is given a value of 2400 in SETUP. quant */

-/* nbits is similar to quant, and is given a value of 54 in SETUP. */
-/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
-/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
-/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
-*/
-/* a constant or a variable, since it is only examined once per frame. */
-/* Leaving it as a variable that is set to .TRUE. seems like a good */

+/* compared against on each iteration. */

+/* Similarly for quant, which is given a value of 2400 in SETUP. quant */
+/* is used in only a few places, and never in the core coding and */

+/* nbits is similar to quant, and is given a value of 54 in SETUP. */
+/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
+/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
+/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
+*/
+/* a constant or a variable, since it is only examined once per frame. */
+/* Leaving it as a variable that is set to .TRUE. seems like a good */

- Calling sequence:
-
- Call create_lpc10_encoder_state(), which returns a pointer to an
- already initialized lpc10_encoder_state structure.
-
- lpc10_encode reads indices 0 through (LPC10_SAMPLES_PER_FRAME-1) of
- array speech[], and writes indices 0 through
- (LPC10_BITS_IN_COMPRESSED_FRAME-1) of array bits[], and both reads
- and writes the lpc10_encoder_state structure contents. The
- lpc10_encoder_state structure should *not* be initialized for every
- frame of encoded speech. Once at the beginning of execution, done
- automatically for you by create_lpc10_encoder_state(), is enough.
-
- init_lpc10_encoder_state() reinitializes the lpc10_encoder_state
- structure. This might be useful if you are finished processing one
- sound sample, and want to reuse the same lpc10_encoder_state
- structure to process another sound sample. There might be other
- uses as well.
-
- Note that the comments in the lpc10/lpcenc.c file imply that indices
- 1 through 180 of array speech[] are read. These comments were
- written for the Fortran version of the code, before it was
- automatically converted to C by the conversion program f2c. f2c
- seems to use the convention that the pointers to arrays passed as
- function arguments point to the first index used in the Fortran
- code, whatever index that might be (usually 1), and then it modifies
- the pointer inside of the function, like so:
-
- if (speech) {
- --speech;
- }
-
- So that the code can access the first value at index 1 and the last
- at index 180. This makes the translated C code "closer" to the
- original Fortran code.
-
- The calling sequence for the decoder is similar to the encoder. The
- only significant difference is that the array bits[] is read
- (indices 0 through (LPC10_BITS_IN_COMPRESSED_FRAME-1)), and the
- array speech[] is written (indices 0 through
- (LPC10_SAMPLES_PER_FRAME-1)).

-/* LPC Processing control variables: */
-
-/* *** Read-only: initialized in setup */
-
-/* Files for Speech, Parameter, and Bitstream Input & Output, */
-/* and message and debug outputs. */
-
-/* Here are the only files which use these variables: */
-
-/* lpcsim.f setup.f trans.f error.f vqsetup.f */
-
-/* Many files which use fdebug are not listed, since it is only used in */
-/* those other files conditionally, to print trace statements. */
-/* integer fsi, fso, fpi, fpo, fbi, fbo, pbin, fmsg, fdebug */
-/* LPC order, Frame size, Quantization rate, Bits per frame, */
-/* Error correction */
-/* Subroutine SETUP is the only place where order is assigned a value, */
-/* and that value is 10. It could increase efficiency 1% or so to */
-/* declare order as a constant (i.e., a Fortran PARAMETER) instead of as
-*/
-/* a variable in a COMMON block, since it is used in many places in the */
-/* core of the coding and decoding routines. Actually, I take that back.
-*/
-/* At least when compiling with f2c, the upper bound of DO loops is */
-/* stored in a local variable before the DO loop begins, and then that is
-*/
-/* compared against on each iteration. */
-/* Similarly for lframe, which is given a value of MAXFRM in SETUP. */
-/* Similarly for quant, which is given a value of 2400 in SETUP. quant */
-/* is used in only a few places, and never in the core coding and */
-/* decoding routines, so it could be eliminated entirely. */
-/* nbits is similar to quant, and is given a value of 54 in SETUP. */
-/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
-/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
-/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
-*/
-/* a constant or a variable, since it is only examined once per frame. */
-/* Leaving it as a variable that is set to .TRUE. seems like a good */
-/* idea, since it does enable some error-correction capability for */
-/* unvoiced frames, with no change in the coding rate, and no noticeable
-*/
-/* quality difference in the decoded speech. */
-/* integer quant, nbits */
-/* *** Read/write: variables for debugging, not needed for LPC algorithm
-*/
-
-/* Current frame, Unstable frames, Output clip count, Max onset buffer,
-*/
-/* Debug listing detail level, Line count on listing page */
-
-/* nframe is not needed for an embedded LPC10 at all. */
-/* nunsfm is initialized to 0 in SETUP, and incremented in subroutine */
-/* ERROR, which is only called from RCCHK. When LPC10 is embedded into */
-/* an application, I would recommend removing the call to ERROR in RCCHK,
-*/
-/* and remove ERROR and nunsfm completely. */
-/* iclip is initialized to 0 in SETUP, and incremented in entry SWRITE in
-*/
-/* sread.f. When LPC10 is embedded into an application, one might want */
-/* to cause it to be incremented in a routine that takes the output of */
-/* SYNTHS and sends it to an audio device. It could be optionally */
-/* displayed, for those that might want to know what it is. */
-/* maxosp is never initialized to 0 in SETUP, although it probably should
-*/
-/* be, and it is updated in subroutine ANALYS. I doubt that its value */
-/* would be of much interest to an application in which LPC10 is */
-/* embedded. */

+/* LPC Processing control variables: */
+
+/* *** Read-only: initialized in setup */
+
+/* Files for Speech, Parameter, and Bitstream Input & Output, */
+/* and message and debug outputs. */
+
+/* Here are the only files which use these variables: */
+
+/* lpcsim.f setup.f trans.f error.f vqsetup.f */
+
+/* Many files which use fdebug are not listed, since it is only used in */
+/* those other files conditionally, to print trace statements. */
+/* integer fsi, fso, fpi, fpo, fbi, fbo, pbin, fmsg, fdebug */
+/* LPC order, Frame size, Quantization rate, Bits per frame, */
+/* Error correction */
+/* Subroutine SETUP is the only place where order is assigned a value, */
+/* and that value is 10. It could increase efficiency 1% or so to */
+/* declare order as a constant (i.e., a Fortran PARAMETER) instead of as
+*/
+/* a variable in a COMMON block, since it is used in many places in the */
+/* core of the coding and decoding routines. Actually, I take that back.
+*/
+/* At least when compiling with f2c, the upper bound of DO loops is */
+/* stored in a local variable before the DO loop begins, and then that is
+*/
+/* compared against on each iteration. */
+/* Similarly for lframe, which is given a value of MAXFRM in SETUP. */
+/* Similarly for quant, which is given a value of 2400 in SETUP. quant */
+/* is used in only a few places, and never in the core coding and */
+/* decoding routines, so it could be eliminated entirely. */
+/* nbits is similar to quant, and is given a value of 54 in SETUP. */
+/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
+/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
+/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
+*/
+/* a constant or a variable, since it is only examined once per frame. */
+/* Leaving it as a variable that is set to .TRUE. seems like a good */
+/* idea, since it does enable some error-correction capability for */
+/* unvoiced frames, with no change in the coding rate, and no noticeable
+*/
+/* quality difference in the decoded speech. */
+/* integer quant, nbits */
+/* *** Read/write: variables for debugging, not needed for LPC algorithm
+*/
+
+/* Current frame, Unstable frames, Output clip count, Max onset buffer,
+*/
+/* Debug listing detail level, Line count on listing page */
+
+/* nframe is not needed for an embedded LPC10 at all. */
+/* nunsfm is initialized to 0 in SETUP, and incremented in subroutine */
+/* ERROR, which is only called from RCCHK. When LPC10 is embedded into */
+/* an application, I would recommend removing the call to ERROR in RCCHK,
+*/
+/* and remove ERROR and nunsfm completely. */
+/* iclip is initialized to 0 in SETUP, and incremented in entry SWRITE in
+*/
+/* sread.f. When LPC10 is embedded into an application, one might want */
+/* to cause it to be incremented in a routine that takes the output of */
+/* SYNTHS and sends it to an audio device. It could be optionally */
+/* displayed, for those that might want to know what it is. */
+/* maxosp is never initialized to 0 in SETUP, although it probably should
+*/
+/* be, and it is updated in subroutine ANALYS. I doubt that its value */
+/* would be of much interest to an application in which LPC10 is */
+/* embedded. */

-/* Voicing Detection (VOICIN) makes voicing decisions for each half */
-/* frame of input speech. Tentative voicing decisions are made two frames*/
-/* in the future (2F) for each half frame. These decisions are carried */
-/* through one frame in the future (1F) to the present (P) frame where */
-/* they are examined and smoothed, resulting in the final voicing */
-/* decisions for each half frame. */
-/* The voicing parameter (signal measurement) column vector (VALUE) */
-/* is based on a rectangular window of speech samples determined by the */
-/* window placement algorithm. The voicing parameter vector contains the*/
-/* AMDF windowed maximum-to-minimum ratio, the zero crossing rate, energy*/
-/* measures, reflection coefficients, and prediction gains. The voicing */
-/* window is placed to avoid contamination of the voicing parameter vector*/
-/* with speech onsets. */
-/* The input signal is then classified as unvoiced (including */
-/* silence) or voiced. This decision is made by a linear discriminant */
-/* function consisting of a dot product of the voicing decision */
-/* coefficient (VDC) row vector with the measurement column vector */
-/* (VALUE). The VDC vector is 2-dimensional, each row vector is optimized*/
-/* for a particular signal-to-noise ratio (SNR). So, before the dot */
-/* product is performed, the SNR is estimated to select the appropriate */
-/* VDC vector. */
-/* The smoothing algorithm is a modified median smoother. The */
-/* voicing discriminant function is used by the smoother to determine how*/
-/* strongly voiced or unvoiced a signal is. The smoothing is further */
-/* modified if a speech onset and a voicing decision transition occur */
-/* within one half frame. In this case, the voicing decision transition */
-/* is extended to the speech onset. For transmission purposes, there are*/
-/* constraints on the duration and transition of voicing decisions. The */
-/* smoother takes these constraints into account. */

+/* Voicing Detection (VOICIN) makes voicing decisions for each half */

+/* through one frame in the future (1F) to the present (P) frame where */
+/* they are examined and smoothed, resulting in the final voicing */
+/* decisions for each half frame. */
+/* The voicing parameter (signal measurement) column vector (VALUE) */
+/* is based on a rectangular window of speech samples determined by the */
+/* window placement algorithm. The voicing parameter vector contains the*/
+/* AMDF windowed maximum-to-minimum ratio, the zero crossing rate, energy*/
+/* measures, reflection coefficients, and prediction gains. The voicing */
+/* window is placed to avoid contamination of the voicing parameter vector*/
+/* with speech onsets. */
+/* The input signal is then classified as unvoiced (including */
+/* silence) or voiced. This decision is made by a linear discriminant */
+/* function consisting of a dot product of the voicing decision */
+/* coefficient (VDC) row vector with the measurement column vector */
+/* (VALUE). The VDC vector is 2-dimensional, each row vector is optimized*/
+/* for a particular signal-to-noise ratio (SNR). So, before the dot */
+/* product is performed, the SNR is estimated to select the appropriate */
+/* VDC vector. */
+/* The smoothing algorithm is a modified median smoother. The */
+/* voicing discriminant function is used by the smoother to determine how*/
+/* strongly voiced or unvoiced a signal is. The smoothing is further */
+/* modified if a speech onset and a voicing decision transition occur */
+/* within one half frame. In this case, the voicing decision transition */
+/* is extended to the speech onset. For transmission purposes, there are*/
+/* constraints on the duration and transition of voicing decisions. The */

+/* declare order as a constant (i.e., a Fortran PARAMETER) instead of as

+/* a variable in a COMMON block, since it is used in many places in the */

+*/
+/* At least when compiling with f2c, the upper bound of DO loops is */
+/* stored in a local variable before the DO loop begins, and then that is
+*/
+/* compared against on each iteration. */
+/* Similarly for lframe, which is given a value of MAXFRM in SETUP. */
+/* Similarly for quant, which is given a value of 2400 in SETUP. quant */

+/* nbits is similar to quant, and is given a value of 54 in SETUP. */
+/* corrp is given a value of .TRUE. in SETUP, and is only used in the */
+/* subroutines ENCODE and DECODE. It doesn't affect the speed of the */
+/* coder significantly whether it is .TRUE. or .FALSE., or whether it is
+*/
+/* a constant or a variable, since it is only examined once per frame. */
+/* Leaving it as a variable that is set to .TRUE. seems like a good */

- PERMUTE is the default. We permute the contents of ARGV as we scan,
- so that eventually all the non-options are at the end. This allows options
- to be given in any order, even with programs that were not written to
- expect this.
-
- RETURN_IN_ORDER is an option available to programs that were written
- to expect options and other ARGV-elements in any order and that care about
- the ordering of the two. We describe each non-option ARGV-element
- as if it were the argument of an option with character code 1.
- Using `-' as the first character of the list of option characters
- selects this mode of operation.
-
- The special argument `--' forces an end of option-scanning regardless
- of the value of `ordering'. In the case of RETURN_IN_ORDER, only
- `--' can cause `getopt' to return -1 with `optind' != ARGC. */

- (aside from the initial '-') are option characters. If `getopt'
- is called repeatedly, it returns successively each of the option characters
- from each of the option elements.
-
- If `getopt' finds another option character, it returns that character,
- updating `optind' and `nextchar' so that the next call to `getopt' can
- resume the scan with the following option character or ARGV-element.
-
- If there are no more option characters, `getopt' returns -1.
- Then `optind' is the index in ARGV of the first ARGV-element
- that is not an option. (The ARGV-elements have been permuted
- so that those that are not options now come last.)
-
- OPTSTRING is a string containing the legitimate option characters.
- If an option character is seen that is not listed in OPTSTRING,
- return '?' after printing an error message. If you set `opterr' to
- zero, the error message is suppressed but we still return '?'.
-
- If a char in OPTSTRING is followed by a colon, that means it wants an arg,
- so the following text in the same ARGV-element, or the text of the following
- ARGV-element, is returned in `optarg'. Two colons mean an option that
- wants an optional arg; if there is text in the current ARGV-element,
- it is returned in `optarg', otherwise `optarg' is set to zero.
-
- If OPTSTRING starts with `-' or `+', it requests different methods of

-
- Long-named options begin with `--' instead of `-'.
- Their names may be abbreviated as long as the abbreviation is unique
- or is an exact match for some defined option. If they have an
- argument, it follows the option name in the same ARGV-element, separated
- from the option name by a `=', or else the in next ARGV-element.
- When `getopt' finds a long-named option, it returns 0 if that option's
- `flag' field is nonzero, the value of the option's `val' field
- if the `flag' field is zero.
-
- The elements of ARGV aren't really const, because we permute them.
- But we pretend they're const in the prototype to be compatible
- with other systems.
-
- LONGOPTS is a vector of `struct option' terminated by an
- element containing a name which is zero.
-
- LONGIND returns the index in LONGOPT of the long-named option found.
- It is only valid when a long-named option has been found by the most

+
+ If an element of ARGV starts with '-', and is not exactly "-" or "--",
+ then it is an option element. The characters of this element
+ (aside from the initial '-') are option characters. If `getopt'
+ is called repeatedly, it returns successively each of the option characters
+ from each of the option elements.
+
+ If `getopt' finds another option character, it returns that character,
+ updating `optind' and `nextchar' so that the next call to `getopt' can
+ resume the scan with the following option character or ARGV-element.
+
+ If there are no more option characters, `getopt' returns -1.
+ Then `optind' is the index in ARGV of the first ARGV-element
+ that is not an option. (The ARGV-elements have been permuted
+ so that those that are not options now come last.)
+
+ OPTSTRING is a string containing the legitimate option characters.
+ If an option character is seen that is not listed in OPTSTRING,
+ return '?' after printing an error message. If you set `opterr' to
+ zero, the error message is suppressed but we still return '?'.
+
+ If a char in OPTSTRING is followed by a colon, that means it wants an arg,
+ so the following text in the same ARGV-element, or the text of the following
+ ARGV-element, is returned in `optarg'. Two colons mean an option that
+ wants an optional arg; if there is text in the current ARGV-element,
+ it is returned in `optarg', otherwise `optarg' is set to zero.
+
+ If OPTSTRING starts with `-' or `+', it requests different methods of
+ handling the non-option ARGV-elements.
+ See the comments about RETURN_IN_ORDER and REQUIRE_ORDER, above.
+
+ Long-named options begin with `--' instead of `-'.
+ Their names may be abbreviated as long as the abbreviation is unique
+ or is an exact match for some defined option. If they have an
+ argument, it follows the option name in the same ARGV-element, separated
+ from the option name by a `=', or else the in next ARGV-element.
+ When `getopt' finds a long-named option, it returns 0 if that option's
+ `flag' field is nonzero, the value of the option's `val' field
+ if the `flag' field is zero.
+
+ The elements of ARGV aren't really const, because we permute them.
+ But we pretend they're const in the prototype to be compatible
+ with other systems.
+
+ LONGOPTS is a vector of `struct option' terminated by an
+ element containing a name which is zero.
+
+ LONGIND returns the index in LONGOPT of the long-named option found.
+ It is only valid when a long-named option has been found by the most
+ recent call.
+
+ If LONG_ONLY is nonzero, '-' as well as '--' can introduce

- * TODO
- * =======
- *
- * - There are two memory pools in use. One in asr_session which is managed

- * These need to be consolidated into one. (basically throw away the one in asr_session)
- *
- * - fs status codes (eg, SWITCH_STATUS_GENERR) and mrcp status codes (MRCP_STATUS_FAILURE)
- * are intermixed badly. this needs cleanup
- *
- * - openmrcp_flush_tts, openmrcp_text_param_tts, openmrcp_numeric_param_tts,
- * openmrcp_float_param_tts need to have functionality added
- *
- * - use a regex for extracting xml from raw result received from mrcp recognition

+ * server. In other words it bridges freeswitch to an external speech

+ *
+ * Uses OpenMrcp (http://wiki.freeswitch.org/wiki/OpenMRCP) as the
+ * the client library.
+ *
+ * TODO
+ * =======
+ *
+ * - There are two memory pools in use. One in asr_session which is managed
+ * by this module, and one in the switch_asr_handle_t, which is managed by freeswitch.
+ * These need to be consolidated into one. (basically throw away the one in asr_session)
+ *
+ * - fs status codes (eg, SWITCH_STATUS_GENERR) and mrcp status codes (MRCP_STATUS_FAILURE)
+ * are intermixed badly. this needs cleanup
+ *
+ * - openmrcp_flush_tts, openmrcp_text_param_tts, openmrcp_numeric_param_tts,
+ * openmrcp_float_param_tts need to have functionality added
+ *
+ * - use a regex for extracting xml from raw result received from mrcp recognition
+ * server
