Comedia Speech presents an implementation of universal Text-To-Speech generation system. It is based on powerful MBrola package and can support different languages.
a speech synthesis engine written entirely in the Java(tm) programming language. FreeTTS was written by the Sun Microsystems Laboratories Speech Team and is based on CMU's Flite engine. FreeTTS also includes a partial JSAPI 1.0
HPKComposer is a composition tool and a software synthetizer built on top of Csound, that allows the creation of VRML worls that follow sounds evolutions and MIDI interactions.
HYDRA is an open-source, platform-neutral library for performing Markov Chain Monte Carlo. It implements the logic of standard MCMC samplers within a framework designed to be easy to use and to extend while allowing integration with other software to
Java Audio Synthesis System: a unit generator based audio synthesis programming environment written in pure Java
JVoiceXML is an implementation of VoiceXML 2.1, the Voice Extensible Markup Language. VoiceXML is designed for creating audio dialogs that feature synthesized speech, digitized audio, recognition of spoken and DTMF key input, recording of spoken input, telephony, and mixed initiative conversations.
LMUSe interprets 3-d L-systems as music.
OriginalSynth allows users to manipulate a small portion of a sound wave (one 44th approximately or 1000/44100 of a second). This is commonly referred to as a "wave table". Users can manipulate the wave table itself by drawing a line with two end points, drawing a point, drawing a curve, moving a point, or deleting a point.
Sonogram analyses sound and speech signals with the methods of the "Fourier Tranformation" (FFT), "Linear Prediction Analyse" (LPC), "Cepstrum Analyse" and the "Wavelet transformation".
