Installing mod_tts_commandline

• In modules.conf, add asr_tts/mod_tts_commandline.

Linux:

• Run make, make install.

Windows:

• copy the msvc project from freeswitch-contrib in grmt\mod_tts_commandline for windows
• add project to Freeswitch.2010.sln and build it (sorry, I didn't test MSVC 2008)

Configuring mod_tts_commandline

• In freeswitch/conf/autoload_configs/modules.conf.xml, uncomment <load module="mod_tts_commandline"/>.
• Edit conf/autoload_configs/tts_commandline.conf.xml.
• Reload configuration by reloadxml (or restarting FreeSWITCH)
• Add tts_commandline to dialplan (or phrase, etc.) like this:

<action application="speak" data="tts_commandline|pico|This is an example of using tts_commandline"/>

Example commands

Using festival's text2wave:

echo ${text} | text2wave -f ${rate} > ${file}

Using festival's server client:

echo ${text} | festival_client --server xxx.xxx.xxx.xxx --otype riff --ttw --output ${file}

(may be needed adjust festival's default sample rate on server)

Using Cepstral's swift:

swift -n ${voice} ${text}  -o ${file}

Using espeak (using sox to adjust sample rate):

echo ${text} | espeak --stdin -v ${voice} --stdout | sox -t wav - -r ${rate} ${file}

Using espeak + mbrola :

echo ${text} | espeak --stdin -v mb/mb-fr4 | mbrola -e /usr/share/mbrola/voices/fr4 - -.au | sox -t au - -r ${rate} ${file}

Using lliaphon + mbrola (French voice fr4) (NB it does not work for me):

echo ${text} | (lliaphon 2>/dev/null) | mbrola -e -f 1.0 -t 0.6 -l 8000 -I /usr/local/share/lliaphon/initfile.lia /usr/share/mbrola/voices/fr4 - ${file}

Using svox pico (from the Android project - supports it-IT, fr-FR, es-ES, de-DE, en-US and en-GB languages:

pico2wave --lang=fr-FR --wave=/tmp/$$.wav ${text} && sox /tmp/$$.wav -r ${rate} ${file} && rm /tmp/$$.wav

Notes on svox pico

Windows:

• build from MSVC 2010 solution file freeswitch-contrib in grmt\svox pico\svoxpico for windows (again sorry I didn't do MSVC 2008)

Linux (at least tested on x64 centos - includes fixes from below and even more fixes from debian-sid and some more fixes to make it compatible with MSVC 2010):

• freeswitch-contrib in grmt/svox\ pico/svox/pico
• sh ./autogen.sh
• ./configure
• make && make install

or alternatively :

Here is a sample of cmd that work on centos 5 64bit (This code includes a fix so it works ok on a 64bit system)

mkdir ~/src
cd ~/src
git clone git://git.debian.org/collab-maint/svox.git svox-git
cd svox-git
git branch -a
git checkout -f origin/debian-sid
cd pico
