WebJul 24, 2024 · Periodicity in speech signals is related to the perception of low pitches (‘periodicity pitch’) (Plomp, 1967; Small, 1970; De Boer, 1976; Evans, 1978; Nordmark, 1978; Moore, 2012; Warren, 2013). It is widely known that pitch conveys essential semantic information in speech and, in tonal languages, changes in voice pitch over time can affect ... WebJan 1, 2014 · This emphasis on periodicity suggests that determining the pitch of a sound wave should be done using a time domain analysis of the waveform. For example, one could calculate the autocorrelation function of the sound wave, and indeed some electronic tuners operate in this manner to calculate the fundamental frequency of a musical sound.
