Abstract

A method for segmenting phone labels to reduce misalignments in order to improve synthetic speech when the phone labels are concatenated comprises:
training a set of HMMs using one of a specific speaker's hand-labeled speech data and speaker-independent speech data;
segmenting the trained set of HMMs using an alignment to produce phone labels, wherein each phone label has a spectral boundary;
using a weighted slope metric to identify bending points of spectral transitions, wherein each bending point corresponds to a spectral boundary; and
correcting a particular spectral boundary of a particular phone label if the particular spectral boundary does not coincide with a particular bending point.
