Lack of invariance problem

Some of the earliest work in the study of how humans perceive speech sounds was conducted by Alvin Liberman and his colleagues at Haskins Laboratories. Using a speech synthesizer, they constructed speech sounds that varied in place of articulation along a continuum from /bɑ/ to /dɑ/ to /ɡɑ/. Listeners were asked to identify which sound they heard and to discriminate between two different sounds. The results of the experiment showed that listeners grouped sounds into discr…

WebHearing loss may specifically exacerbate the fundamental problem of lack of invariance in acoustic-phonetic relationships. The fundamental problem faced by all theories of speech perception derives from the lack of invariance in the relationship between the acoustic patterns of speech and the linguistic interpretation of those patterns.

Via an empirical study on BBOB, Websimulated data with a known lack of invariance, models using parcels as indicators erroneously indicated that measurement invariance existed more often than models using items as indicators. Moreover, item-by-item tests of measurement invariance were often more informative than were tests of the entire matrix of factor loadings. tara weber wiki

WebJan 28, 2024 · The main proposed explanations for this effect revolve around the idea that adult speech perception involves a “native filter”: an automatic, involuntary, and not very plastic mapping of each incoming sound, foreign or not, onto native phonetic categories—i.e., the vowels and consonants of the native language (9–13).
