• For a commercial option try Lumenvox, had very good results. For “free”
  you can try google tts but you never know when google will decide to pull the plug on something.

• I had been using google tts, but it started requiring a captcha for my browser, and via linux I can’t access http://translate.google.com/translate_tts?q=test (redirects to captcha)

  as so, its not reliable

• I have a similar situation here, I want to include TTS in my asterisk IVR
  system. Could someone give suggestion(s) please, I prefer open-source thanks in advance!

• Hello,

  what follows is a mostly incomplete list of Text To Speech (TTS) and Speech To Text (STT)
  solutions available for asterisk.

  -Regarding the TTS free and open source available options:

  Asterisk comes with festival (http://www.cstr.ed.ac.uk/projects/festival/) support
  (app_festival) already build in. Decent quality, supports mainly English.

  There is support for flite (http://www.festvox.org/flite/) available as a 3rd party plugin : http://zaf.github.io/Asterisk-Flite/ Quality at par with festival, much easier to setup and use, supports only English.

  Also support for espeak (http://espeak.sourceforge.net/):
  http://zaf.github.io/Asterisk-eSpeak/ Average quality, supports a wide range of languages.

  -Free plugins/scripts that provide TTS from a remote not-so-free service:

  GoogleTTS : http://zaf.github.io/asterisk-googletts/ Great quality, lots of languages, free of charge but NOT suitable for any serious/commercial use. It is not a service Google officially provides but just a hack that gets synthesized speech data from their translate page. It’s more suitable for testing/developing and home use.

  MsTTS: http://zaf.github.io/asterisk-mstts/ using Microsoft’s Translator voice synthesis engine.

  iSpeech: http://zaf.github.io/asterisk-ispeech/ using iSpeech API (http://www.ispeech.org)

  -Other non free solutions:

  Cepstral: http://www.cepstral.com/en/telephony/asterisk

  Speech Technology Group: http://www.asteriskexchange.com/listings/1001

  -Regarding the STT options:

  Google Speech: http://zaf.github.io/asterisk-speech-recog/ the API is limited at the moment in something like 50 requests/day and considered a technology preview.

  iSpeech: http://zaf.github.io/asterisk-ispeech/

  Lumevox: http://www.lumenvox.com/partners/digium/asterisk.aspx

  Sphinx: http://cmusphinx.sourceforge.net/wiki/asteriskdetails
