WebHence speakers are expected to vary their output along a continuum of hyper- and hypospeech. The theory suggests that the lack of invariance that speech signals commonly exhibit (Perkell and Klatt 1986) is a direct consequence of this adaptive organization (cf MacNeilage 1970). WebA theory of acoustic invariance claims that the universal set of phonetic features used in natural language can be characterized by invariant properties derived directly from the acoustic signal, that the perceptual mechanism is specifically tuned to extract these properties, and that they form the primary perceptual attributes used in ongoing …
WebTranslation invariance means that the system produces exactly the same response, regardless of how its input is shifted. For example, a face-detector might report "FACE FOUND" for all three images in the top row. Equivariance means that the system works equally well across positions, but its response shifts with the position of the target. ...
