[Freeswitch-dev] [Freeswitch-users] C SAY API

If you break and store everything as separate words, then you'll be ignoring
the intonation.
I think there should be a table that maps phrases (a sequence of words) to a
wave file. The matching algorithm should always try to find the longest
phrase. This way you can improve the quality by simply recording additional
phrases. Of course, the phrases should be language-specific.
Probably there could be another function like this:
say_sentence_text(""en", "voice", You have
<messages>{0}</messages> new messages as of <datetime>{1}</datetime>", "10",
"12/18/2006 10:00 AM");
But this is still language specific. Probably there could be another table
that has the sentence pattern like above with some alpha-numeric ID (one map
per language) and then the say_setence function can take either sentence ID
or sentence pattern with a list of parameters like this:
say_sentence("en", "voice", "vmail.new_messages", "10",
"12/18/2006 10:00 AM");

That applies how you want it to proceed with the preprocessor. Supply the
digits to the preprocessor and it will give the list of words or filenames
to sequence.
1400
we may need output,
one thousand four hundred
one four zero zero
It is upto the user to choose it.
Also with the API,
switch_channel_set_variable(channel, "language", "en");
switch_channel_set_variable(channel, "language", "en","voice");
voice - indicates whose voice set to select

Kannaiyan
