These pages describe IPOX, an experimental speech synthesis system, based in part on YorkTalk. YorkTalk and IPOX differ from main-stream speech synthesis systems such as DecTalk in that no use is made of rewriting rules. Instead, input strings are analyzed using declarative, constraint-based phrase structure grammars. The representation thus obtained, a metrical-prosodic tree, is assigned a compositional phonetic interpretation in terms of paramaters for a formant synthesizer.
Samples of synthetic speech, generated by IPOX, are included as illustrations, as well as screen clips of the graphic representations displayed during analysis and generation.
Note: In order to play the speech samples, your Web browser must be able to handle 16-bit
.wav files sampled at 11025 Hz.
