Abstract

Various embodiments of systems and methods for phoneme identification in speech signals are described herein. A base frequency for a speech signal is determined at a computing device. Curvatures at extrema points are calculated based on a normalized phoneme function. The normalized phoneme function is a function of a time period of a phoneme function and a value of the phoneme function. The calculated curvatures are compared with reference curvatures of phonemes. When a sequence of the calculated curvatures matches a sequence of the reference curvatures, a corresponding phoneme is identified.
