mbrola - multilingual software speech synthesizer
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
mbrola understands following command line options.
