[Freeswitch-users] Error playing TTS using flite

Yungwei, I *think* sayPhrase is not supported by flite - only by other
TTS engines. 
Try calling it in this javascript format:
session.speak(ttsLib,ttsVoice,text);

Subject: [Freeswitch-users] Error playing TTS using flite

Hi,

I am testing tts using flite against freeswitch (snapshot downloaded
last week) on CentOS 5.
I'm getting "Invalid speech module [cepstral]!" and "Invalid TTS module"
errors when dialing 9911 from my SIP client.
What am I missing here? Thanks.

During installatio, I uncommented the following in modules.conf so
mod_flite is installed. mod_cepstral remains commented.
asr_tts/mod_unimrcp
asr_tts/mod_flite
asr_tts/mod_pocketsphinx

After installation, I uncommented mod_flite in
/usr/local/freeswitch/conf/autoload_configs/modules.conf.xml
    <!-- ASR /TTS -->
    <load module="mod_flite"/>
    <!-- <load module="mod_pocketsphinx"/> -->
    <!-- <load module="mod_cepstral"/> -->
    <!-- <load module="mod_tts_commandline"/> -->
    <!-- <load module="mod_rss"/> -->

Here's my dial-plan
  <extension name="test1">
        <condition field="destination_number" expression="^9911$">
                <action application="set" data="tts_engine=flite"/>
                <action application="set" data="tts_voice=kal"/>
                <action application="javascript" data="dtmf_test.js" />
        </condition>
  </extension>

dtmf_test.js is copied from
http://wiki.freeswitch.org/wiki/Examples_ivrmenu_js to
/usr/local/freeswitch/scripts folder.
The phrase macro is also copied from that link to
/usr/local/freeswitch/conf/lang/en/demo folder.
