Note it is quite easy to implement new duration methods in Scheme directly. If a segment is found that does not appear in the list a default duration of 0.1 seconds is assigned, and a warning message generated. This method requires minimum and inherent durations for each phoneme in the phoneset. Each member of this list is a three-tuple, of phone name, inherent duration and minimum duration. 19.4 CART durations Two very similar methods of duration prediction by CART tree are supported.
Tree simply predicts durations directly for each segment.
This method requires means and standard deviations for each phone. For some other duration models that affect an inherent duration by some factor this method has been used. The above formula will generate the desired result. Klatt and Klatt-like rules can be implemented in the this way without adding a new method.
