from the NetBSD maintainer: This voice provides an American English male voice using a residual excited LPC diphone synthesis method. It uses the CMU Lexicon pronunciations. Prosodic phrasing is provided by a statistically trained model using part of speech and local distribution of breaks. Intonation is provided by a CART tree predicting ToBI accents and an F0 contour generated from a model trained from natural speech. The duration model is also trained from data using a CART tree.
