Sign Communication in Cri du Chat Syndrome
Peer reviewed Peer reviewed
Direct linkDirect link
Erlenkamp, Sonja; Kristoffersen, Kristian Emil – Journal of Communication Disorders, 2010
This paper presents findings from a study on the use of sign supported Norwegian (SSN) in two individuals with Cri du chat syndrome (CCS). The study gives a first account of some selected aspects of production and intelligibility of SSN in CCS. Possible deviance in manual parameters, in particular inter- and/or intra-subject variation in the use…

Preservation of Second Formant Transitions during Simultaneous Communication: A Locus Equation Perspective.
Peer reviewed Peer reviewed
Baillargeon, Megan; McLeod, Amy; Metz, Dale Evan; Schiavetti, Nicholas; Whitehead, Robert L. – Journal of Communication Disorders, 2002
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…

Effect of Sign Task on Speech Timing in Simultaneous Communication.
Peer reviewed Peer reviewed
Whitehead, Robert L.; Schiavetti, Nicholas; Whitehead, Brenda H.; Metz, Dale Evan – Journal of Communication Disorders, 1997
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.…

Sentence Intonation and Syllable Stress in Speech Produced during Simultaneous Communication.
Peer reviewed Peer reviewed
Whitehead, Robert L.; Schiavetti, Nicholas; Metz, Dale Evan; Gallant, Deborah; Whitehead, Brenda H. – Journal of Communication Disorders, 2000
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…

Perception of the Voicing Distinction in Speech Produced during Simultaneous Communication
Peer reviewed Peer reviewed
Direct linkDirect link
MacKenzie, Douglas J.; Schiavetti, Nicholas; Whitehead, Robert L.; Metz, Dale Evan – Journal of Communication Disorders, 2006
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 Comparison of Verbal, Sign, and Simultaneous Systems for the Acquisition of Receptive Language by an Autistic Boy.
Peer reviewed Peer reviewed
Wherry, Jeffrey N.; Edwards, R. P. – Journal of Communication Disorders, 1983
The effectiveness of verbal, sign, and simultaneous systems for the acquisition of receptive language by an autistic boy was investigated. Results suggest nonsignificant differences among the three methods. (Author/SEW)

Intelligibility of Speech Produced during Simultaneous Communication
Peer reviewed Peer reviewed
Direct linkDirect link
Whitehead, Robert L.; Schiavetti, Nicholas; MacKenzie, Douglas J.; Metz, Dale Evan – Journal of Communication Disorders, 2004
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…
