Speech Synthesis
Speech synthesis is the artificial production of human speech. A system used for this purpose is termed a speech synthesizer, and can be implemented in software or hardware. Speech synthesis systems are often called text-to-speech (TTS) systems in reference to their ability to convert text into speech. However, there exist systems that can only render symbolic linguistic representations like phonetic transcriptions into speech.

MBROLA
MBROLA is a high-quality, diphone-based speech synthesizer which is available for free. It is provided by the TCTS Lab of the Faculte Polytechnique de Mons (Belgium) which aims to obtain a set a speech synthesizers for as many languages as possible which will be free of use for non-commercial, non-military applications.
MBROLA 2.00 takes a list of phonemes as input, together with prosodic information (duration of phonemes and a piecewise linear description of pitch), and produces 16bit speech samples at the sampling frequency of the diphone database (typically 16kHz). (It is therefore NOT a Text-To-Speech (TTS) synthesizer, since it does not accept raw text as input.) Databases are now being prepared for English, Spanish, Italian, Dutch, and Romanian.
