Line Spectrum pair density modeling for speech applications

摘要

Novel techniques for providing superior performance and sound quality in speech applications, such as speech synthesis, speech coding, and automatic speech recognition, are hereby disclosed. In one illustrative embodiment, a method includes modeling a speech signal with parameters comprising line spectrum pairs. Density parameters are provided based on the density of the line spectrum pairs. A speech application output, such as synthesized speech, is provided based at least in part on the line spectrum pair density parameters. The line spectrum pair density parameters use computing resources efficiently while providing improved performance and sound quality in the speech application output.
