Festival is a text to speech engine developed by the British at the Centre for Speech Technology Research (CSTR) division at the University of Edinburgh. It sounds very robot-like. The speech it creates is understandable but it is not anything remotely close human-sounding. It works, and it can be used for text to speech, but it is not the best free software alternative.
Installation[edit]
The basic festival software is typically available as package named festival but the optional voice packages tend to be named festvox-{voice} (festvox-clb-arctic-hts, festvox-kal-diphone, etc).
Voice files are placed in /usr/share/festival/voices/us/
Basic Use[edit]
Festival can say anything piped to it as long as the -tts option:
echo 'hello' | festival --tts
You can pipe files to festival and have them read:
echo "Hello world" > example.txt
festival --tts < example.txt
Festival can be configured by creating a $HOME/.festivalrc configuration file.
Festival will create a incriminating text file called $HOME/.festival_history with every command sent to it.
Festival is one of many programs that can be used with the Linux speech-dispatcher daemon. Programs like Kmouth will use Festival for text-to-speech if speech-dispatcher is configured to use it (Festival not the default on any GNU/Linux distribution we are aware of).
Audio Quality[edit]
The text to speech output generated by Festival does not sound very natural, it is very robot-like. It is understandable. It's just not very human-sounding and it is not very impressive compared to commercial solution and it is not as good as the free software mimic alternative.
echo 'Hello, this is a test of the emergency broadcasting system' | festival --tts
