NAME
mbrola - multilingual software speech synthesizer
SYNOPSIS
mbrola [options]<voice_database><pho_file>...<output_file>
DESCRIPTION
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.
