Computing the reliability of acoustic information in speech

Invited talk presented at the Dept. of Linguistics, Northwestern University, May 2013.

Abstract: Many researchers have observed that speech sounds vary considerably across different contexts, an issue known as the lack of invariance. Given this variability, how much information is conveyed by individual acoustic cues? That is, how reliably do specific cues distinguish phonological contrasts?.. Read more →

Combining cues to recognize speech

Acoustic measurements of phonetic cues to word-medial voicing

Toscano, J. C., & McMurray, B. (2012, November). Poster presented at the 53rd Annual Meeting of the Psychonomic Society, Minneapolis, MN.

Abstract: A great deal of work in speech has argued that invariant acoustic cues do not exist, leading many researchers to conclude that listeners use specialized representations, such as talkers’ inferred gestures, instead... Read more →

The consequences of lexical sensitivity to fine grained detail

Solving the problems of integrating cues and processing speech in time

McMurray, B., & Toscano, J. C. (2012, October). Paper presented at the 164th Meeting of the Acoustical Society of America, Kansas City, MO.

AbstractWork on language comprehension is classically divided into two fields. Speech perception asks how listeners cope with variability from factors like talker and coarticulation to compute some phoneme-like unit; and word recognition assumed these units to ask how listeners cope with time and match the input to the lexicon...

Cue Integration With Categories: Weighting Acoustic Cues in Speech Using Unsupervised Learning and Distributional Statistics

Toscano, J. C., & McMurray, B. (2010). Cognitive Science, 34, 434-464.

Abstract: During speech perception, listeners make judgments about the phonological category of sounds by taking advantage of multiple acoustic cues for each phonological contrast. Perceptual experiments have shown that listeners weight these cues differently. How do listeners weight and combine acoustic cues to arrive at an overall estimate of the category for a speech sound?.. Read more →
