Psychophysics of speech and speech-like stimuli
Tammo Houtgast · The Journal of the Acoustical Society of America · 1995
The starting point is the representation of speech in the spectro-temporal domain. From this representation, a number of interesting physical characteristics can be derived on the dynamic properties of speech. These include the temporal and spectral envelopes, correlation patterns, and synchrony. The perceptual relevance of these characteristics will be illustrated by reviewing a number of psychophysical data from experiments including speech-like sounds of specific laboratory-made dynamic stimuli. Within the context of low bit-rate coding and automatic recognition, the ultimate goal of this comparison between speech characteristics and psychophysics is to help identify the cues in the speech signal which are perceptually significant.
