Interactions of speaking condition and auditory feedback on vowel production in postlingually deaf adults with cochlear implants
2007
Journal of the Acoustical Society of America
Vowel contrasts in the formant space ͑expressed in mels͒ were larger in the clear than in the fast condition, both for controls and for implant users at all three time samples. ...
The implant users' contrasts were larger with hearing on than off and improved from one month to one year postimplant. ...

Effects of masking noise on vowel and sibilant contrasts in normal-hearing speakers and postlingually deafened cochlear implant users
2007
Journal of the Acoustical Society of America
Seven cochlear implant users and seven normal-hearing controls pronounced utterances containing the vowels /i/, /u/, // and /ae/ and the sibilants /s/ and /b/ while hearing their speech mixed with noise ...
Speakers' average vowel duration and SPL generally rose with increasing N/S. Average vowel contrast was initially flat or rising; at higher N/S levels, it fell. ...
