Ehealth Parent Education For Hearing Aid Management: A Pilot Randomized Controlled Trial, Karen F. Muñoz, Guadalupe G. San Miguel, Tyson S. Barrett, Courtney Kasin, Kelsey Baughman, Bailey Reynolds, Caitlyn Ritter, Makynzie Larsen, John J. Whicker, Michael P. Twohig

Psychology Student Research

Objective: Parents frequently experience challenges implementing daily routines important for consistent hearing aid management. Education that supports parents in learning new information and gaining confidence is essential for intervention success. We conducted a pilot study to test an eHealth program to determine if we could implement the program with adherence and affect important behavioral outcomes compared to treatment as usual.

Design: Randomized controlled trial

Study sample: Parents of children birth to 42 months who use hearing aids. Eighty-two parents were randomly assigned to the intervention or treatment-as-usual group. Four parents assigned to the intervention group did not continue after baseline …

Effects Of Masking Noise On Vowel And Sibilant Contrasts In Normal-Hearing Speakers And Postlingually Deafened Cochlear Implant Users, Joseph Perkell, Margaret Denny, Harlan Lane, Frank Guenther, Melanie Matthies, Mark Tiede, Jennell Vick, Majid Zandipour, Ellen Burton

Harlan Lane

The role of auditory feedback in speech production was investigated by examining speakers' phonemic contrasts produced under increases in the noise to signal ratio (N/S). Seven cochlear implant users and seven normal-hearing controls pronounced utterances containing the vowels /i/, /u/, /ε/ and /æ/ and the sibilants /s/ and /ʃ/ while hearing their speech mixed with noise at seven equally spaced levels between their thresholds of detection and discomfort. 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. A contrast increase is interpreted as reflecting …

A Preliminary Study Of The Effects Of Cochlear Implants On The Production Of Sibilants, Melanie L. Matthies, Mario A. Svirsky, Harlan L. Lane, Joseph S. Perkell

Harlan Lane

The potential influence of auditory information in the production of /s/ and /ʃ/ was explored for postlingually deafened adults with four-channel Ineraid cochlear implants. Analyses of the spectra of the sibilant sounds were compared for speech obtained prior to implant activation, after early implant use and after 6 months of use. In addition, the output of the Ineraid device (measured at each of the four electrodes) was analyzed with pre- and postactivation speech samples to explore whether the speech production changes were potentially audible to the cochlear-implant user. Results indicated that subjects who showed abnormally low or incorrect contrast between …

Changes In Voice-Onset Time In Speakers With Cochlear Implants, Harlan Lane, Jane Wozniak, Joseph Perkell

Harlan Lane

Voice-onset time (VOT) and syllable duration were measured for the English plosives in /Cɑd/ (C=consonant) context spoken by four postlingually deafened recipients of multichannel (Ineraid) cochlear implants. Recordings were made of their speech before, and at intervals following, activation of the speech processors of their implants. Three patients reduced mean syllable duration following activation. Using measures of VOT and syllable duration from speakers with normal hearing [Volaitis and Miller, J. Acoust. Soc. Am. 92, 723–735 (1992)] and from the subjects of this study, VOT is shown to vary approximately linearly with syllable duration over the ranges produced here. Therefore, the …

Effects Of Short-Term Auditory Deprivation On Speech Production In Adult Cochlear Implant Users, Mario A. Svirsky, Harlan Lane, Joseph S. Perkell, Jane Wozniak

Harlan Lane

Speech production parameters of three postlingually deafened adults who use cochlear implants were measured: after 24 h of auditory deprivation (which was achieved by turning the subject's speech processor off); after turning the speech processor back on; and after turning the speech processor off again. The measured parameters included vowel acoustics [F1, F2, F0, sound-pressure level (SPL), duration and H1–H2, the amplitude difference between the first two spectral harmonics, a correlate of breathiness] while reading word lists, and average airflow during the reading of passages. Changes in speech processor state (on-to-off or vice versa) were accompanied by numerous changes in …

Perception And Production Of /R/ Allophones Improve With Hearing From A Cochlear Implant, Melanie L. Matthies, Frank H. Guenther, Margaret Denny, Joseph S. Perkell, Ellen Burton, Jennell Vick, Harlan Lane, Mark Tiede, Majid Zandipour

Harlan Lane

Tongue shape can vary greatly for allophones of /r/ produced in different phonetic contexts but the primary acoustic cue used by listeners, lowered F3, remains stable. For the current study, it was hypothesized that auditory feedback maintains the speech motor control mechanisms that are constraining acoustic variability of F3 in /r/; thus the listener's percept remains /r/ despite the range of articulatory configurations employed by the speaker. Given the potential importance of auditory feedback, postlingually deafened speakers should show larger acoustic variation in /r/ allophones than hearing controls, and auditory feedback from a cochlear implant could reduce that variation over …

Interactions Of Speaking Condition And Auditory Feedback On Vowel Production In Postlingually Deaf Adults With Cochlear Implants, Lucie Ménard, Marek Polak, Margaret Denny, Ellen Burton, Harlan Lane, Melanie Matthies, Nicole Marrone, Joseph Perkell, Mark Tiede, Jennell Vick

Harlan Lane

This study investigates the effects of speaking condition and auditory feedback on vowel production by postlingually deafened adults. Thirteen cochlear implant users produced repetitions of nine American English vowels prior to implantation, and at one month and one year after implantation. There were three speaking conditions (clear, normal, and fast), and two feedback conditions after implantation (implant processor turned on and off). Ten normal-hearing controls were also recorded once. Vowel contrasts in the formant space (expressed in mels) were larger in the clear than in the fast condition, both for controls and for implant users at all three time samples. …
