Automatic segmentation in speech synthesis |
(57) In a system having a speech inventory that includes phone labels that are concatenated
to form synthetic speech, a method for segmenting the phone labels comprises:
performing an alignment on a trained set of HMMs to produce phone labels that are
segmented, wherein each phone label has a spectral boundary; and
performing spectral boundary correction on the phone labels, wherein spectral boundary
correction re-aligns each spectral boundary using bending points of spectral transitions,
wherein the phone labels having spectral boundary correction are used for speech synthesis.
