Build Status

A lightweight ROS package for Text-to-Speech (TTS) generation. It is actually a wrapper around popular TTS engines, it supports a bunch of both online and offline third parties.

  • Open-source third parties:

    • espeak based on the espeak utility, a multi-lingual software speech synthesizer link
    • Festival based on the Festival project, by the University of Edinburgh link
    • GNUstep the TTS engine of the GNUstep project. In Lubuntu 16.04, seems to be a wrapper around festival. link
    • MaryTTS An open-source, multilingual Text-to-Speech Synthesis platform written in Java. This package makes use of the web service that is shipped with MaryTTS 5.2. download page direct v5.2 download link
    • pico2wave based on pico2wave, a small footprint TTS link
    • speech_dispatcher Uses the spd-say tool of the Speech Dispatcher project, developed by Freebsoft. link
  • Proprietary engines:

    • AT&T (WEBSERVICE) AT&T TTS webservice link
    • Google TTS (WEBSERVICE) most notably used in Google Translate link
    • Ivona (WEBSERVICE) uses the IVONA TTS webservice for developpers link
    • Microsoft (WEBSERVICE) the speech synthesizer developed by Microsoft for its OS link
