Internal Program Version: mbrola  3.3

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.
