Abstract
Development of pitch extractors is a continuous effort. Workers in this field need a quantitative, objective method for rapid evaluation and comparison of various techniques that are implemented. Previous methods involved laborious, visual comparison of the speech wave with the output of the pitch extractor or the use of unrealistic inputs such as a periodic pulse generator or a spoken list of isolated syllables. Recently, testing of pitch extractors was facilitated with the aid of a digital computer. A pitch-pulse master tape was produced from 6 min of clear speech, using techniques of B. Gold [J. Acoust. Soc. Am. 34, 916–921 (1962)]. A program was written to compare the “ideal” pitch pulses from the master tape with the outputs of experimental circuits having the same speech input. The program detects minor inaccuracies, as well as gross errors in pitch, and permits rapid diagnosis of circuit performance.
