Fix: reset phoneme table if speech is cancelled while switched to a second language. "speak": add -z options (same as for "espeak"). Numbers: Add option to speak "and" before hundreds. git-svn-id: https://espeak.svn.sourceforge.net/svnroot/espeak/trunk@143 d46cf337-b52f-0410-862d-fd96e6ae7743

<h2>MBROLA VOICES</h2>
|
|
<hr>
|
|
The Mbrola project is a collection of diphone voices for speech synthesis. They do not include any text-to-phoneme translation, so this must be done by another program. The Mbrola voices are cost-free but are not open source. They are available from the Mbrola website at:<br>
|
|
<a href="http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html">http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html</a>
|
|
|
|
<p>
|
|
eSpeak can be used as a front-end to Mbrola. It provides the spelling-to-phoneme translation and intonation, which Mbrola then uses to generate speech sound.
|
|
|
|
<h3>Voice Names</h3>
|
|
|
|
To use a Mbrola voice, eSpeak needs information to translate from its own phonemes to the equivalent Mbrola phonemes. This has been set up for only some voices so far.
|
|
<p>
|
|
The eSpeak voices which use Mbrola are named as:<br>
|
|
<b>mb-</b>xxx
|
|
<p>
|
|
where xxx is the name of a Mbrola voice (eg. <b>mb-en1</b> for the Mbrola "<b>en1</b>" English voice). These voice files are in eSpeak's directory <code>espeak-data/voices/mbrola</code>.
|
|
<p>
|
|
The installation instructions below use the Mbrola voice "en1" as an example. You can use other mbrola voices for which there is an equivalent eSpeak voice in <code>espeak-data/voices/mbrola</code>.
|
|
<p>
|
|
There are some additional eSpeak Mbrola voices which speak English text using a Mbrola voice for a different language. These contain the name of the Mbrola voice with a suffix <b>-en</b>. For example, the voice <b>mb-de4-en</b> will speak English text with a German accent by using the Mbrola <b>de4</b> voice.
|
|
|
|
<h3>Windows Installation</h3>
|
|
|
|
The SAPI5 version of eSpeak uses the mbrola.dll.
|
|
<ol>
|
|
<li>Install eSpeak. Include the voice <b>mb-en1</b> in the
|
|
list of voices during the eSpeak installation.
|
|
<p>
|
|
<li>Install the PC/Windows version of Mbrola (MbrolaTools35.exe) from:
|
|
<a href="http://www.tcts.fpms.ac.be/synthesis/mbrola/bin/pcwin/MbrolaTools35.exe"> http://www.tcts.fpms.ac.be/synthesis/mbrola/bin/pcwin/MbrolaTools35.exe</a>.
|
|
<p>
|
|
<li>Get the <b>en1</b> voice from:
|
|
<a href="http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html"> http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html</a>
|
|
unpack the archive, and copy the "<b>en1</b>" data file (not the whole "en1"
|
|
directory) into
|
|
<code>C:/Program Files/eSpeak/espeak-data/mbrola</code>.
|
|
<p>
|
|
<li>Use the voice <b>espeak-MB-EN1</b> from the list of SAPI5 voices.
|
|
</ol>
|
|
<h3>Linux Installation</h3>
|
|
|
|
I don't think there's a Linux shared library version of Mbrola (equivalent to mbrola.dll), so eSpeak has to pipe phoneme data to the command-line Mbrola.
|
|
<ol>
|
|
<li>To install the Linux Mbrola binary, download:
|
|
<a href="http://www.tcts.fpms.ac.be/synthesis/mbrola/bin/pclinux/mbr301h.zip"> http://www.tcts.fpms.ac.be/synthesis/mbrola/bin/pclinux/mbr301h.zip</a>.
|
|
Unpack the archive, and copy and rename the file: <code>mbrola-linux-i386</code> to
|
|
<code>mbrola</code> somewhere in your executable path (eg. <code>/usr/bin/mbrola</code> ).
|
|
<p>
|
|
<li>Get the en1 voice from:
|
|
<a href="http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html"> http://www.tcts.fpms.ac.be/synthesis/mbrola/mbrcopybin.html</a>.
|
|
Unpack the archive, and copy the "<b>en1</b>" data file (not the whole "en1"
|
|
directory) somewhere convenient (eg. <code>/usr/share/mbrola/en1</code> ).
|
|
<p>
|
|
<li>If you use the eSpeak voice "<b>mb-en1</b>" then eSpeak will generate
|
|
Mbrola phoneme data on its stdout. You can pipe this into Mbrola.
|
|
<p>
|
|
<code>espeak -v mb-en1 -f textfile | mbrola -e /usr/share/mbrola/en1 -
|
|
test.wav</code>
|
|
<p>
|
|
will put the Mbrola speech output into a WAV file. Or you can pipe the output from Mbrola through aplay:
|
|
<p>
|
|
<code>espeak -v mb-en1 -f textfile | mbrola -e /usr/share/mbrola/en1 - - | aplay -r16000 -fS16</code>
|
|
<p>
|
|
The -e option prevents Mbrola from stopping if it finds a combination
|
|
of phonemes which it doesn't recognise.
|
|
<p>
|
|
Some mbrola voices (de5, de6) use a sample rate of 22050 Hz. These need -r22050 rather than -r16000.
|
|
</ol>
|
|
<h3>Mbrola Voice Files</h3>
|
|
|
|
eSpeak's voice files for Mbrola voices are in directory <code>espeak-data/voices/mbrola</code>. They contain a line:<br>
|
|
<code>mbrola <voice> <translation></code>
|
|
<br>
|
|
eg.<br>
|
|
<code>mbrola en1 en1_phtrans</code>
|
|
<ul>
|
|
<li><b><voice></b> is the name of the Mbrola voice.
|
|
<p>
|
|
<li><b><translation></b> is a translation file to convert between eSpeak phonemes and the equivalent Mbrola phonemes. These are kept in:
|
|
<code>espeak-data/mbrola_ph</code>
|
|
</ul>
|
|
They are binary files which are compiled, using espeakedit, from source files in <code>phsource/mbrola</code>. Details to be defined.
