Cochlear implant users experience difficulties controlling their vocalizations compared to normal hearing peers. However, less is known about their voice quality. The primary aim of the present study was to determine if cochlear implant users' voice quality would be categorized as dysphonic by the Acoustic Voice Quality Index (AVQI) and smoothed cepstral peak prominence (CPPS). A secondary aim was to determine if vocal quality is further impacted when using bilateral implants compared to using only one implant. The final aim was to determine how residual hearing impacts voice quality. Twenty-seven cochlear implant users participated in the present study and were recorded while sustaining a vowel and while reading a standardized passage. These recordings were analyzed to calculate the AVQI and CPPS. The results indicate that CI users' voice quality was detrimentally affected by using their CI, raising to the level of a dysphonic voice. Specifically, when using their CI, mean AVQI scores were 4.0 and mean CPPS values were 11.4 dB, which indicates dysphonia. There were no significant differences in voice quality when comparing participants with bilateral implants to those with one implant. Finally, for participants with residual hearing, as hearing thresholds worsened, the likelihood of a dysphonic voice decreased.

The goal of this study was to understand the interaction between the voice source spectral shape, formant tuning, and fundamental frequency in determining the vocal tract contribution to vocal intensity. Computational voice simulations were performed with parametric variations in both vocal fold and vocal tract configurations. The vocal tract contribution to vocal intensity was quantified as the difference in the A-weighted sound pressure level between the radiated sound pressure and the sound pressure at the glottis.

This study focuses on suprasegmental features and investigates how the use of a second tonal dialect influences the production of tones in the first dialect among bidialectal speakers of Chengdu Mandarin (CM) and Standard Mandarin (SM). Using a word-naming task, this study analyzed the acoustic differences between tones in SM and CM that share similar pitch contours and assessed the impact of SM use on CM tone production. How bidialectal listeners perceptually map SM tones onto CM categories was further evaluated using a dissimilarity rating task.

Background: The Serious Illness Conversation Guide was developed to support high quality goals of care conversations with seriously ill patients; however, guide implementation for patients with limited English proficiency (LEP) has not been studied. This evaluation aimed to explore serious illness conversations with hospitalized LEP patients, defined as those with a non-English language documented, from clinician and interpreter perspectives; and assess differences in documentation in the electronic medical record (EMR) as a quality improvement effort.
Methods: Parallel mixed methods evaluation including thematic analysis of observations and interviews with medical interpreters ( = 14), occupational therapists ( = 9), registered dietitians ( = 6), and resident physicians ( = 3) of a quaternary academic hospital in the United States.
