PurposeA group of 10 prelingually deafened children with cochlear implants (CIs) formed a choir and received 21 months of formal music training. The purpose of this study was to evaluate the singing proficiency of these children.MethodThe participants included all choir members (7 girls and 3 boys, mean age of 9.5 years old) who were unilateral CI users. Meanwhile, 8 age-matched children with normal hearing were recruited as controls and were trained on 1 song for 2 weeks. Individual singing samples without instrument accompaniment were recorded from all participants. The singing samples were subject to acoustic analysis in which the fundamental frequency (F0) of each note was extracted and the duration was measured. Five metrics were developed and computed to quantify the accuracy of their pitch and rhythm performance. The 5 metrics included (a) percent correct of F0 contour direction of adjacent notes, (b) mean deviation of the normalized F0 across the notes, (c) mean deviation of the pitch intervals, (d) mean deviation of adjacent note duration ratio, and (e) mean absolute deviation of note duration.ResultsThe choir members with CIs demonstrated high accuracy in both pitch and tempo measures and performed on par with the children with normal hearing. Early start of music training after implantation and use of bimodal hearing contributed to the development of better music ability in these children with CIs.ConclusionThese findings indicated that rigorous music training could facilitate high singing proficiency in prelingually deafened children with CIs.

Introduction. The focus of this study was the analysis of objective acoustic characteristics of voice in children with cochlear implants. The objective of this study was to compare acoustic parameters of voice in children with cochlear implants and normal hearing children of the same age, and to determine differences, if there were any. Material and Methods. There were 60 children (aged from 6 to 13) included in this prospective study. They were divided into 2 groups: children with cochlear implants (30) and normal hearing children with normal speech development (30). The most stable voice sample was analyzed using a software program Dr Speech: Vocal Assessment. Objective acoustic analysis of voice included 13 acoustic parameters. Results. Standard deviation of fundamental frequency was significantly (p=0.000) higher in children with cochlear implants, as well as the values of harmonic to noise ratio (p=0.003) and signal to noise ratio (p=0.000) parameters. Values of jitter %, shimmer %, normalized noise energy, fundamental frequency tremor and amplitude tremor showed no significant differences between the two groups. However, the values of parameters that refer to voice frequency (habitual fundamental frequency, mean fundamental frequency, min fundamental frequency and max fundamental frequency) and the mean value of voice intensity (p=0.004), were significantly higher in the boys and the girls with cochlear implants than in the normal hearing children. Conclusion. Gender non-related parameters of hoarseness did not show significant differences between the children with cochlear implants and the normal hearing children; the results of cochlear implantation and voice and speech education were therefore positive. However, the children with cochlear implants of both gender showed significantly higher values of voice intensity, voice pitch and insufficient control of voice pitch variation.

Purpose The aims of this study were to (a) determine a metric for describing full-time use (FTU), (b) establish whether age at FTU in children with cochlear implants (CIs) predicts language at 3 years of age better than age at surgery, and (c) describe the extent of FTU and length of time it took to establish FTU in this population. Method This retrospective analysis examined receptive and expressive language outcomes at 3 years of age for 40 children with CIs. Multiple linear regression analyses were run with age at surgery and age at FTU as predictor variables. FTU definitions included 8 hr of device use and 80% of average waking hours for a typically developing child. Descriptive statistics were used to describe the establishment and degree of FTU. Results Although 8 hr of daily wear is typically considered FTU in the literature, the 80% hearing hours percentage metric accounts for more variability in outcomes. For both receptive and expressive language, age at FTU was found to be a better predictor of outcomes than age at surgery. It took an average of 17 months for children in this cohort to establish FTU, and only 52.5% reached this milestone by the time they were 3 years old. Conclusions Children with normal hearing can access spoken language whenever they are awake, and the amount of time young children are awake increases with age. A metric that incorporates the percentage of time that children with CIs have access to sound as compared to their same-aged peers with normal hearing accounts for more variability in outcomes than using an arbitrary number of hours. Although early FTU is not possible without surgery occurring at a young age, device placement does not guarantee use and does not predict language outcomes as well as age at FTU.

Vocants are precursors to speech and are facially neutral. The presence of these speechlike vocalizations was evident during the precursors to mature phonology called “protophones”. The prosodic feature of duration of the nuclei plays a crucial role in the shift of prelexical to mature speech, since speech intelligibility is closely related to the control of duration. The aim of this work is to determine whether cochlear implants (CIs) positively trigger language acquisition and the development of verbal skills. Recent literature findings are compared and discussed with the performance of two Greek congenitally hearing-impaired infants who were matched with three normal-hearing (NH) infants. This work highlighted an important weakness of the prosodic abilities of young infants with CIs.

Background: Self-monitoring has been shown to be an essential skill for various aspects of our lives, including our health, education, and interpersonal relationships. Likewise, the ability to monitor one's speech reception in noisy environments may be a fundamental skill for communication, particularly for those who are often confronted with challenging listening environments, such as students and children with hearing loss. Purpose: The purpose of this project was to determine if normal-hearing children, normal-hearing adults, and children with cochlear implants can monitor their listening ability in noise and recognize when they are not able to perceive spoken messages. Research Design: Participants were administered an Objective-Subjective listening task in which their subjective judgments of their ability to understand sentences from the Coordinate Response Measure corpus presented in speech spectrum noise were compared to their objective performance on the same task. Study Sample: Participants included 41 normal-hearing children, 35 normal-hearing adults, and 10 children with cochlear implants. Data Collection and Analysis: On the Objective-Subjective listening task, the level of the masker noise remained constant at 63 dB SPL, while the level of the target sentences varied over a 12 dB range in a block of trials. Psychometric functions, relating proportion correct (Objective condition) and proportion perceived as intelligible (Subjective condition) to target/masker ratio (T/M), were estimated for each participant. Thresholds were defined as the T/M required to produce 51% correct (Objective condition) and 51% perceived as intelligible (Subjective condition). Discrepancy scores between listeners’ threshold estimates in the Objective and Subjective conditions served as an index of self-monitoring ability. In addition, the normal-hearing children were administered tests of cognitive skills and academic achievement, and results from these measures were compared to findings on the Objective-Subjective listening task. Results: Nearly half of the children with normal hearing significantly overestimated their listening in noise ability on the Objective-Subjective listening task, compared to less than 9% of the adults. There was a significant correlation between age and results on the Objective-Subjective task, indicating that the younger children in the sample (age 7–12 yr) tended to overestimate their listening ability more than the adolescents and adults. Among the children with cochlear implants, eight of the 10 participants significantly overestimated their listening ability (as compared to 13 of the 24 normal-hearing children in the same age range). We did not find a significant relationship between results on the Objective-Subjective listening task and performance on the given measures of academic achievement or intelligence. Conclusions: Findings from this study suggest that many children with normal hearing and children with cochlear implants often fail to recognize when they encounter conditions in which their listening ability is compromised. These results may have practical implications for classroom learning, particularly for children with hearing loss in mainstream settings.
