(description
"This voice provides a British RP English male voice using a
residual excited LPC diphone synthesis method. It uses a
modified Oxford Advanced Learners' Dictionary for 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.")))
