This study investigated the preservation of second formant transition acoustic cues to intelligibility in speech produced during simultaneous communication (SC) from a locus equation perspective with 12 normal hearing, experienced sign language users. Results were consistent with previous research indicating that temporal alterations produced by…

This study investigated the perception of voice onset time (VOT) in speech produced during simultaneous communication (SC). Four normally hearing, experienced sign language users were recorded under SC and speech alone (SA) conditions speaking stimulus words with voiced and voiceless initial consonants embedded in a sentence. Twelve…

Fourteen deaf elementary children (eight from total communication and six from oral classes) and seven non-hearing-impaired peers were given tasks designed to elicit spontaneous language. Results favored hearing children on all measures. When comparing the two deaf groups, few differences emerged in measures of verbal output and communicativeness.…

A study involving 12 hearing sign language users examined the effect of the signing task on temporal features of speech during simultaneous communication (SC). Results indicated longer sentence duration for SC than speech-only conditions, and longer anticipatory duration of the diphthong and interword interval preceding the experimental words.…

A study investigated prosodic variables of syllable stress and intonation contours in speech produced during the simultaneous communication (SC) of ten hearing sign language users. Results indicated longer sentence duration for SC than speech only conditions. Vowel duration and frequency differences between stressed and unstressed syllables were…
