Cue-integration and context effects in speech: Evidence against speaking-rate normalization

Toscano, J. C., & McMurray, B. (2012). Attention, Perception, and Psychophysics, 74, 1284-1301.

Abstract:¬†Listeners are able to accurately recognize speech despite variation in acoustic cues across contexts, such as different speaking rates. Previous work has suggested that listeners use rate information (indicated by vowel length; VL) to modify their use of context-dependent acoustic cues, like voice-onset time (VOT), a primary cue to voicing...

Acoustic cue integration in natural speech

Empirical and computational results

Toscano, J. C. and McMurray, B. (2006, October). Talk presented at the 12th Midcontinental Workshop on Phonology, University of Iowa, Iowa City, IA.

Abstract:

Multiple acoustic cues in the speech signal often contribute to a single phonetic categorization. For example, in the perception of word-initial voicing in stop consonants, voice onset time (VOT) and vowel length have both been shown to influence voicing judgments (Summerfield, 1981)...

Cue integration during spoken word recognition

One way for listeners to cope with variability in the speech signal is to use multiple acoustic cues when identifying speech sounds. Multiple cues often contribute to a single phonetic distinction in speech, and listeners can combine different sources of acoustic information to help resolve ambiguity.¬†For example, one of the primary acoustic cues to the voicing distinction in English, the difference between the sounds ‘b’ and ‘p’, is voice-onset time (VOT)...
