- title Festival - Text-to-Speech
You can take advantage of Text-To-Speech in Ubuntu by using a program called Festival. Out of the box, Festival doesn't work with ESD (the default sound server up to Gutsy), Pulse``Audio (the default sound server since Hardy) or ALSA, so some changes are required to get it up and running. This guide provides instructions on how to get Festival working on Ubuntu with ESD, Pulse``Audio and ALSA. If you are using a version of Ubuntu prior to Hardy, and you don't want to use Festival with ESD, you will have to disable ESD in the Sounds preferences dialog. In that case, other multimedia applications won't be able to play audio at the same time.
目录
Installation
Install Festival by typing the following command in a Terminal:
sudo apt-get install festival
Note: Additional voices are available in the Ubuntu respositories. Type "festvox" in Synaptic Package Manager for a list of language packages.
Configuration for ESD
Install esdplay and esddsp, which are part of the esound-clients package:
sudo apt-get install esound-clients
If you'd like to use ESD for output on a per-run basis, you can run festival through the esddsp wrapper script. Using this approach, the wrapper must be called every time you run festival, or else you will get an error message saying can't open /dev/dsp.
esddsp festival
If you want festival to always use ESD for output, you can configure this globally, for all users, or on a per-user basis. To configure globally use the configuration file /etc/festival.scm. To configure locally use the configuration file ~/festival.scm.
- Open the configuration file by typing
gksudo gedit /etc/festival.scmorgksudo gedit ~/festival.scmin a terminal. - Add the following lines at the end of the file:
(Parameter.set 'Audio_Command "esdplay $FILE") (Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Required_Format 'snd)
1.#3 Save the file.
Configuration for PulseAudio
Note: Festival may work with Pulse``Audio out of the box. If so, nothing further needs to be done and this section can be skipped.
Install paplay and padsp, which are part of the pulseaudio-utils package:
sudo apt-get install pulseaudio-utils
If you'd like to use Pulse``Audio for output on a per-run basis, you can run festival through the padsp wrapper script. Using this approach, the wrapper must be called every time you run festival, or else you will get an error message saying can't open /dev/dsp.
padsp festival
If you want festival to always use Pulse``Audio for output, you can configure this globally, for all users, or on a per-user basis. To configure globally use the configuration file /etc/festival.scm. To configure locally use the configuration file ~/festival.scm.
- Open the configuration file by typing
gksudo gedit /etc/festival.scmorgksudo gedit ~/festival.scmin a terminal. - Add the following lines at the end of the file:
(Parameter.set 'Audio_Command "paplay $FILE") (Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Required_Format 'snd)
1.#3 Save the file.
Configuration for ALSA
Note: It is hard to use ALSA and ESD on the same system, if it is possible at all. Here it is assumed that you are using ALSA instead of ESD.
Insert of the end of the file /etc/festival.scm the lines
(Parameter.set 'Audio_Command "aplay -D plug:dmix -q -c 1 -t raw -f s16 -r $SR $FILE") (Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Required_Format 'snd)
On some configurations it may be necessary to remove the "-D plug:dmix" part of the aplay command above.
Testing
Test your setup by typing in a Terminal
festival
You will be presented with a > prompt. Type
(SayText "Hello")
The computer should say "hello".
To listen to a text file named FILENAME, type
(tts "FILENAME" nil)
Note FILENAME must be in quote marks.
