Abstract
Jitter, shimmer, and Harmonics-to-Noise Ratio (HNR) are three acoustic parameters that provide information about sub-phonetic characteristics of a speaker’s voice. They have been deemed invaluable in pathological voice diagnoses, speech synthesis, voice biometrics, speech signal processing, and animal bioacoustics. There are even claims that one of them or a combination of the three plays a significant role in infant cry bioacoustics. Linguists are yet to tap into the potential that these three parameters offer for the classification of phonation types. This paper reviews the expansive literature and provides objective Just Noticeable Difference (JND) thresholds that can be leveraged to account for linguistic analyses of non-pathological voice qualities.
