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 effects of noise and filtering on the intelligibility of speech produced during simultaneous communication (SC). Four normal hearing, experienced sign language users were recorded under SC and speech alone (SA) conditions speaking Boothroyd's forced-choice phonetic contrast material designed for measurement of speech…

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 involving 20 listeners investigated the potential influence of alterations in the temporal structure of speech produced during simultaneous communication on the perception of final consonant voicing. Results found that accurate perception was not impaired by the durational changes accompanying the typically slower speech pattern of…

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…

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…

A study of 10 typical women investigated the effect of fingerspelling task length on temporal characteristics and perceived naturalness of speech produced during simultaneous communication. Speech produced during simultaneous communication was rated as less natural and demonstrated increased interword interval, diphthong, work, and sentence…

This study investigated the overall intelligibility of speech produced during simultaneous communication (SC). Four hearing, experienced sign language users were recorded under SC and speech alone (SA) conditions speaking Boothroyd's (1985) forced-choice phonetic contrast material designed for measurement of speech intelligibility. Twelve…

This study investigated the acoustical and perceptual characteristics of vowels in speech produced during simultaneous communication (SC). Twelve normal hearing, experienced sign language users were recorded under SC and speech alone (SA) conditions speaking a set of sentences containing monosyllabic words designed for measurement of vowel…

Students who are deaf or hard of hearing (n=231) used the Language Background Questionnaire (LBQ) to self assess their sign language and spoken communication skills. Formal independent estimates of these skills were also conducted. Comparison of results indicates a high degree of congruence between the self and formal assessments, which…
