Festival is a general multi-lingual speech synthesis system developed at CSTR (Centre for Speech Technology Research).
Festival offers a general framework for building speech synthesis systems as well as including examples of various modules. As a whole it offers full text to speech through a number APIs: from shell level, though a Scheme command interpreter, as a C++ library, from Java, and an Emacs interface. Festival is multi-lingual (currently British English, American English, and Spanish.)
Contents
Installation
Install festival from official repositories. You need a voice package like festival-english or festival-us. Further languages are available in official repositories and in AUR.
Test festival:
$ echo "This is an example. Arch is the best." | festival --tts
If your hear all the example text, you sucessfully installed a TTS system.
If you do not hear anything, hear something strange, or get a message about /dev/dsp, see the Troubleshooting section.
HTS compatibility patches
Some say that HTS voices for Festival are the best ones freely available. Sadly they are not compatible with Festival >2.1 without patching it (and the new voice versions are not made available for downloading).
You can install the patched version from AUR: festival-patched-hts and festival-hts-voices-patched
Using with PulseAudio
Add these lines to the end of your .festivalrc file, or to /usr/share/festival/festival.scm :
(Parameter.set 'Audio_Required_Format 'aiff) (Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Command "paplay $FILE --client-name=Festival --stream-name=Speech")
Configuration
You can set a default voice by adding these lines to the end of your ~/.festivalrc file, or to /usr/share/festival/festival.scm:
(set! voice_default 'voice_cmu_us_slt_arctic_hts)
You can also set the default voice in /usr/share/festival/voices.scm
You must be root and the voices are at the end of the file. Just switch them around
Usage
Read a text file:
festival --tts /path/to/letter.txt
Read a text file to wav:
cat letter.txt | text2wave -o letter.wav
Interactive mode (testing voices etc.)
festival has an interactive prompt you can use for testing. Some examples (with sample output):
$ festival [...] festival>
List available voices:
festival> (voice.list) (cstr_us_awb_arctic_multisyn kal_diphone don_diphone)
Set voice:
festival> (voice_cstr_us_awb_arctic_multisyn) #<voice 0x1545b90>
Speak:
festival> (SayText '"test this is a test oh no a test bla test") inserting pause after: t. Inserting pause [...] id _63 ; name t ; id _65 ; name # ; #<Utterance 0x7f7c0c144810>
More:
festival> help "The Festival Speech Synthesizer System: Help
Quit: ctrl+d or
festival> (quit)
Example script
One classic app that can make use of this is ping. Use this script to constantly ping a host, and return ping if success, fail is not:
#!/bin/bash while :; do ping -c 1 $1 && (echo "Ping" | festival --tts) || (echo "Fail" | festival --tts) done
Note that this does not really work on multisynth voices, as they take a while to prepare before playing.
Troubleshooting
Can't open /dev/dsp
If festival returns the following error message:
Linux: can't open /dev/dsp
Switch to ALSA output by adding these lines to the end of your .festivalrc file, or to /usr/share/festival/festival.scm (source):
(Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Command "aplay -q -c 1 -t raw -f s16 -r $SR $FILE")
Alsa playing at wrong speed
If the solution above gives you a squeaky voice, you might want to try:
(Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Command "aplay -Dplug:default -f S16_LE -r $SR $FILE")
