The Effect of Speaking Rate on Voice-onset-time Is Talker-specific
نویسندگان
چکیده
Talkers differ in phonetic properties of speech. One such property is voice-onset-time (VOT), an important marker of the voicing contrast in English stop consonants. Research has shown that VOT is affected by speaking rate: for any given talker, VOT increases as rate slows. The current work examines whether this contextual influence varies across talkers. Many tokens of /ti/ (Experiment 1) or /pi/ and /ki/ (Experiment 2) were elicited from talkers across a range of rates. VOT and syllable duration were measured for each token. The results showed that although VOT increased as rate slowed for all talkers, the extent of this increase varied significantly across talkers. For a given talker, however, the extent of the increase was stable across a change in place of articulation. These findings suggest that talker differences in phonetic properties of speech reflect talker-specific contextual influences.

Individual Talker and Token Covariation in the Production of Multiple Cues to Stop Voicing
BACKGROUND/AIMS Previous research found that individual talkers have consistent differences in the production of segments impacting the perception of their speech by others. Speakers also produce multiple acoustic-phonetic cues to phonological contrasts. Less is known about how multiple cues covary within a phonetic category and across talkers. We examined differences in individual talkers acro...
متن کاملStructure in talker-specific phonetic realization: Covariation of stop consonant VOT in American English
Variation across talkers in the acoustic-phonetic realization of speech sounds is a pervasive property of spoken language. The present study provides evidence that variation across talkers in the realization of American English stop consonants is highly structured. Positive voice onset time (VOT) was examined for all six word-initial stop categories in isolated productions of CVC syllables and ...
متن کاملDifferential neural contributions to native- and foreign-language talker identification.
Humans are remarkably adept at identifying individuals by the sound of their voice, a behavior supported by the nervous system's ability to integrate information from voice and speech perception. Talker-identification abilities are significantly impaired when listeners are unfamiliar with the language being spoken. Recent behavioral studies describing the language-familiarity effect implicate f...

متن کاملEffects of Within-Talker Variability on Speech Intelligibility in Mandarin-Speaking Adult and Pediatric Cochlear Implant Patients
Cochlear implant (CI) speech performance is typically evaluated using well-enunciated speech produced at a normal rate by a single talker. CI users often have greater difficulty with variations in speech production encountered in everyday listening. Within a single talker, speaking rate, amplitude, duration, and voice pitch information may be quite variable, depending on the production context....
