Automatic speech feature classification for children with cochlear implants
نویسندگان
چکیده
Following pediatric cochlear implantation, it is important to monitor the recipient’s auditory perception skills to (a) determine appropriate therapeutic strategies, and (b) guide adjustment (mapping) of how the CI stimulation is distributed over its channels. One evaluation tool used in clinical and research settings is the OlimSpac [1], which assesses perception at the phonetic feature level by asking children to repeat stimuli that are presented aurally. Errors in the child’s repetition of an item are taken to reflect errors in their perception of the stimulus features. While normally administered by a trained clinician who must score the child’s productions, we present here results from a study involving automatic scoring of productions from 17 pediatric CI patients aged 3;0 to 6;10 years. Taken independently, the automated system was in agreement with human feature classifications over 93% of the time overall (range was 99% for vowel height to 89% for consonant voicing) for stimuli on which human judges were in unanimous agreement. Automatic scoring of utterances from young CI recipients could allow the OlimSpac and similar testing procedures to be used more frequently in a clinical setting, and even administered remotely under appropriate conditions.

Speech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
متن کاملCorrelation between Auditory Spectral Resolution and Speech Perception in Children with Cochlear Implants
Background: Variability in speech performance is a major concern for children with cochlear implants (CIs). Spectral resolution is an important acoustic component in speech perception. Considerable variability and limitations of spectral resolution in children with CIs may lead to individual differences in speech performance. The aim of this study was to assess the correlation between auditory ...
متن کاملComparison of the high-frequency morpho-syntactic structures of cochlear implant children and children with normal hearing aged 4-6 years
Introduction: Children with cochlear implants experience problems at all language domains, and have more problems in morpho-syntactic skills than others domains. Considering the importance of morphology and syntax in developing of communication skills of children, this study compared the use of high-frequency morpho-syntactic structures among 4-6 years old children with cochlear implants and ty...

Objectives: Studies reported that children with Cochlear Implant (Cl) presented difficulties in grammatical acquisition. The Persian language is inflectional. The present study aimed to compare word-level inflections in the language samples of CI recipients and healthy-hearing children. Methods: Thirty children were recruited in this descriptive-analytical cross-sectional study. The Language S...
متن کاملSpeech Intelligibility of Cochlear-Implanted and Normal-Hearing Children
Introduction: Speech intelligibility, the ability to be understood verbally by listeners, is the gold standard for assessing the effectiveness of cochlear implantation. Thus, the goal of this study was to compare the speech intelligibility between normal-hearing and cochlear-implanted children using the Persian intelligibility test. Materials and Methods: Twenty-six cochlear-implanted childre...
