{{From|https://help.ubuntu.com/community/TextToSpeech}} {{Languages|UbuntuHelp:TextToSpeech}} #title Festival - Text-to-Speech You can take advantage of Text-To-Speech in Ubuntu by using a program called ''Festival''. Festival doesn't work with ESD (the default sound mixer) or ALSA out of the box, 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 or ALSA. If you don't 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. == Installation == Install Festival by typing the following command in a Terminal: <code><nowiki>sudo apt-get install festival</nowiki></code> '''Note:''' Additional voices are available in the Ubuntu respositories. Type "festival" in ''Synaptic Package Manager'' for a list of packages. == Configuration for ESD == Install ''esdplay'', which is part of the ''esound-clients'' package: <code><nowiki>sudo apt-get install esound-clients</nowiki></code> You need to configure festival so that it sends its output through ESD. Otherwise, you will get a ''can't open /dev/dsp'' error when you try to run Festival. <ol><li>Open the file ''/etc/festival.scm'' by typing <code><nowiki>gksudo gedit /etc/festival.scm</nowiki></code> in a Terminal. </li><li>Add the following lines at the end of the file:</li></ol> <pre><nowiki>(Parameter.set 'Audio_Command "esdplay $FILE") (Parameter.set 'Audio_Method 'Audio_Command) (Parameter.set 'Audio_Required_Format 'snd)</nowiki></pre> 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 <code><nowiki>/etc/festival.scm</nowiki></code> the lines <pre><nowiki>(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)</nowiki></pre> Some sources leave off the <code><nowiki>-D plug:dmix </nowiki></code>; maybe that works for older systems, but it didn't work in my Feisty. == Testing == Test your setup by typing in a Terminal <code><nowiki>festival</nowiki></code> You will be presented with a ''>'' prompt. Type <code><nowiki>(SayText "Hello")</nowiki></code> The computer should say "hello". To listen to a text file named ''FILENAME'', type <code><nowiki>(tts "FILENAME" nil)</nowiki></code> Note ''FILENAME'' must be in quote marks. [[category:UbuntuHelp]]
