Voice quality control for high quality speech reconstruction
First Claim
1. A method of reproducing a speech sequence of a user through a communication device of the user comprising:
- detecting a speech sequence from the user through the communication device;
recognizing a phoneme sequence within the detected speech sequence;
forming a confidence level of each phoneme within the recognized phoneme sequence;
audibly reproducing the recognized phoneme sequence for the user through the communication device; and
gradually highlighting or degrading a voice quality of at least some phonemes of the recognized phoneme sequence based upon the formed confidence level of the at least some phonemes.

Abstract
A method and apparatus are provided for reproducing a speech sequence of a user through a communication device of the user. The method includes the steps of detecting a speech sequence from the user through the communication device, recognizing a phoneme sequence within the detected speech sequence and forming a confidence level of each phoneme within the recognized phoneme sequence. The method further includes the steps of audibly reproducing the recognized phoneme sequence for the user through the communication device and gradually highlighting or degrading a voice quality of at least some phonemes of the recognized phoneme sequence based upon the formed confidence level of the at least some phonemes.

11. A communication device that reproducing a speech sequence of a user comprising:
-
a speech detector that detects a speech sequence from the user;
a Hidden Markov Model (HMM) processor that recognizes a phoneme sequence within the detected speech sequence;
a confidence processor that forms a confidence level of each phoneme within the recognized phoneme sequence;
a reproduction processor that audibly reproduces the recognized phoneme sequence for the user through a speaker of the communication device; and
a phoneme processor that gradually highlights a voice quality of at least some phonemes of the recognized phoneme sequence based upon the formed confidence level of the at least some phonemes. - View Dependent Claims (12, 13, 14, 15, 16)
