mbrola - multilingual software speech synthesizer


mbrola [options]<voice_database><pho_file>...<output_file>


mbrola is a speech synthesizer based on the concatenation of diphones. It takes a list
of phonemes as input, together with prosodic information (duration of phonemes and a
piecewise linear description of pitch), and produces speech samples on 16 bits
(linear), at the sampling frequency of the diphone database.

It is therefore NOT a Text-To-Speech (TTS) synthesizer, since it does not accept raw text
as input. In order to obtain a full TTS system, you need to use this synthesizer in
combination with a text processing system that produces phonetic and prosodic commands.
For instance, you may use package freephone to obtain complete English TTS.

A `-' instead of pho_file or output_file means stdin or stdout. Extension of output_file
( raw, au, wav, aiff ) tells the wanted audio format.


mbrola understands following command line options.
