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.

-c comment_char

Set COMMENT char (escape sequence in pho files).

-F flush_command

Set FLUSH command name.

-v volume

-l voice_freq

Voice frequency. Target frequency for voice quality in Hz.

-R rename_list

Phoneme rename list of the form: `a A b B ...'

-C clone_list
