PSY315H5 Lecture Notes - Lecture 2: Voice-Onset Time, Vocal Tract, Vocal Folds
Document Summary
Ability to differentiate acoustics that are meaningful or irrelevant. Introduce the notion of a continuum, perceptual stimuli can be followed along a scale or continuum. Speech sounds that we hear that are categorically different from one another in terms of degree. If you identify a continuum where you are bearing the hue of red becoming more and more yellow like. Do you see a difference between these two colour squares: what we see typically is that peoples" scores is consistently high, the same pattern of responses found with a range of perceptual stimuli; ex. brightness, musical tones, etc. Pa vs ba opening of lips to release air then vibration of larynx (voice box: involve the same physical gestures, difference is based on the timing of the gestures. Pa = larynx vibration begins after lips open. Ba = larynx vibration begins around the same time the lips open. /b/ = short vot (-20 (a little bit before) to 0ms)
