Document Summary
Gating task involves presenting gradually increasing amounts of a word. This enables the isolation points of words to be found. Sounds are perceived in categories regardless of variation in speaker. There"s no one-to-one mapping of acoustic signal to a speech sound. Different instances (tokens) of the same phoneme are slightly different pronunciation category. What are some factors that lead to inter-speaker variability? assumptions about common ground. Pronunciation, lexical choices, syntactic choices, social choices, Specific acoustic cues may differ between speakers, but the. Listeners adapt to foreign accents/dialects through duration of the sound is the same learn/maintain speaker-specific representations. Category boundary comes from typical distribution of acoustic features along a continuum. Adjust your categories to fit a new speaker"s productions. How do they work and what do they tell us/measure? transcription. We study speech perception thru categorization, discrimination, and. Categorization experiments give subject a non-word syllable like (cid:824)a?i(cid:825) and manipulate (cid:824)? (cid:825) to vary b/w two sounds on an acoustic continuum.
