Pitch is the psychological correlate of the fundamental frequency and is important for speech perception. [1] The quality of the sound is dependent on the highness or lowness of tone pitch along with other acoustic cues. It is a major cue for the identification of suprasegmental aspects of speech; [2] helpful in gender identification; [3,4] age identification; [5,6] emotional arousal; [7] cultural variations; [8] and sociocultural aspects. [9] The change in pitch does not vary the meaning of spoken words or sentences in most of the Indo-European languages such as English, Hindi, and Sanskrit, but in Sino-Tibetan languages such as Mandarin, Cantonese, and Thai, the change in the pitch contours changes the meaning of the words. Such languages where the meaning of the words is dependent on the pitch contour within a syllable are known as tonal languages.Perception of pitch is a topic of scientific enquiry. The contour tone of pitch is perceived categorically. [10] The categorical perception indicates that the gradually morphed stimulus is perceived as discrete identities in the auditory system. Thus, the pitch perception is categorical when the continuum involves the change in the direction of the pitch contour. [11] In the last decade, a surge of interest has been developed to assess the pitch contour contrasts of tonal languages. [11][12][13][14] Mandarin Chinese is one such tonal language involving contour tones which is perceived categorically. Researchers reported strong evidences of categorical perception for pitch contrasts in Mandarin, [11] Thai, [15] and Cantonese listeners. [16] Xi et al. [13] have found that categorical perception of lexical tones in Mandarin Chinese is perceived categorically.
