Mod flite
From FreeSWITCH Wiki
- Flite (aka Festival Lite) is a small embeddable TTS (Text to Speech) engine that's totally free.
- Works on FreeBSD, Mac, Linux and Windows.
- Don't load mod_cepstral and mod_flite at the same time. (symbol collision).
- Voices are 16khz, and are:
- slt
- rms
- awb
- kal
Installing mod_flite
- In modules.conf uncomment asr_tts/mod_flite; (note that's the one at the top level of your src directory and NOT to be confused with the freeswitch/conf/modules.conf.xml file which you will also have to edit later - see below). This installation has been written assuming that you are going to be compiling this module (at time of this edit - Jan2010 - it doesn't come with the deb sources apt-get method mentioned on another page).
Comment out asr_tts/mod_cepstral from the same file. Both modules cannot be used together.
- Run make, make install.
- In freeswitch/conf/autoload_configs/modules.conf.xml, uncomment <load module="mod_flite"/>. Comment out <load module="mod_cepstral"/>.
