| Abstract: |
Speech signal parameters are extracted from time-series data corresponding to different sound units containing the same vowel. The extracted parameters are used to train a statistical model, such as a Hidden Markov-based Model, that has a data structure for separately modeling the nuclear trajectory region of the vowel and its surrounding transition elements. The model is trained as through embedded re-estimation to automatically determine optimally aligned models that identify the nuclear trajectory region. The boundaries of the nuclear trajectory region serve to delimit the overlap region for subsequent sound unit concatenation.

What is claimed is:
1. A method for identifying a unit overlap region for concatenative speech synthesis, comprising:
- defining a statistical model for representing time-varying properties of speech;
- providing a plurality of time-series data corresponding to different sound units containing the same vowel;
- extracting speech signal parameters from said time-series data and using said parameters to train said statistical model;
- using said trained statistical model to identify a recurring sequence in said time-series data and associating said recurring sequence with a nuclear trajectory region of said vowel;
- using said recurring sequence to delimit the unit overlap region for concatenative speech synthesis.
