Pitch period detection and chaining: method and evaluation.
An algorithm is presented which detects quasi-periodic parts in a given speech signal, and provides the fundamental frequency for these parts. The algorithm analyses the structure of the time-amplitude representation of the speech signal. It first determines potential 'period-twins' and then observes whether these period-twins are members of a 'period-chain'. The performance of the algorithm is evaluated. The results are given as absolute and relative figures and are compared with other methods.
