Objective: This study explored tone production, tone perception and intelligibility of produced speech in Mandarin-speaking prelingually deaf children with at least 5 years of cochlear implant (CI) experience. Another focus was on the predictive value of tone perception and tone production as they relate to speech intelligibility. Design: Cross-sectional research. Study sample: Thirty-three prelingually deafened children aged over eight years with over five years of experience with CI underwent tests for tone perception, tone production, and the Speech Intelligibility Rating (SIR). A Pearson correlation and a stepwise regression analysis were used to estimate the correlations among tone perception, tone production, and SIR scores. Results: The mean scores for tone perception, tone production, and SIR were 76.88%, 90.08%, and 4.08, respectively. Moderately positive Pearson correlations were found between tone perception and production, tone production and SIR, and tone perception and SIR (p?0.01, p?0.01 and p?0.01, respectively). In the stepwise regression analysis, tone production, as the major predictor, accounted for 29% of the variations in the SIR (p?0.01). Conclusions: Mandarin-speaking cochlear-implanted children with sufficient duration of CI use produce intelligent speech. Speech intelligibility can be predicted by tone production performance. 相似文献

Background: Auditory neuropathy spectrum disorder (ANSD) is a distinct type of SNHL that is characterized by the presence of otoacoustic emissions and/or cochlear microphonics. Cochlear implantation was initially not recommended for ANSD children, later studies showed variable outcomes among those subjects.Objective: To assess the auditory and speech performance of cochlear implanted children with auditory neuropathy spectrum disorder (ANSD) and to compare these results to those obtained from cochlear implanted children with sensorineural hearing loss (SNHL)Material and methods: 18 cochlear implanted children with ANSD and 40 cochlear implanted children with SNHL were included in this study. Auditory and speech performance results were compared across both subject groups using the Category of Auditory Performance (CAP) and Speech Intelligibility Rate (SIR) tests, with measurements recorded one year post implantation.Results: Cochlear implanted children with ANSD showed clinically significant improvements that were comparable to those observed from cochlear implanted subjects without ANSD.Conclusions: Children with ANSD benefit from early cochlear implantation and can reach similar auditory and speech performance results as that achieved by children without ANSD. 相似文献

Objectives
To investigate the influence of age, and age-at-implantation, on speech production intelligibility in prelingually deaf pediatric cochlear implant recipients.Methods
Forty prelingually, profoundly deaf children who received cochlear implants between 8 and 40 months of age. Their age at testing ranged between 2.5 and 18 years. Children were recorded repeating the 10 sentences in the Beginner's Intelligibility Test. These recordings were played back to normal-hearing listeners who were unfamiliar with deaf speech and who were instructed to write down what they heard. They also rated each subject for the intelligibility of their speech production on a 5-point rating-scale. The main outcome measures were the percentage of target words correctly transcribed, and the intelligibility ratings, in both cases averaged across 3 normal-hearing listeners.Results
The data showed a strong effect of age at testing, with older children being more intelligible. This effect was particularly pronounced for children implanted in the first 24 months of life, all of whom had speech production intelligibility scores of 80% or higher when they were tested at age 5.5 years or older. This was true for only 5 out of 9 children implanted at age 25-36 months.Conclusions
Profoundly deaf children who receive cochlear implants in the first 2 years of life produce highly intelligible speech before the age of 6. This is also true for most, but not all children implanted in their third year. 相似文献5.
目的:应用听觉行为分级(CAP)和言语可懂度分级(SIR)评估语后聋患者人工耳蜗植入后言语交流状况,探讨其得分与听力下降时间、植入时间、术前助听器使用情况的关系。方法:回顾分析23例语后聋人工耳蜗植入者的临床资料,收集其听力下降时间、植入时间、术前助听器使用情况等相关资料,应用CAP、SIR分级评估其言语交流状况。运用IBM SPSS Statistics19软件进行统计描述及结果分析。结果:CAP分级平均得分为6.13分,统计分析示CAP分级与听力下降时间、植入时间、术前助听器使用时间无显著相关关系(均P〉0.05)。患者均为语后聋,其SIR分级的平均得分为4.91分。结论:语后聋患者人工耳蜗植入后CAP分级与听力下降时间、植入时间、术前助听器使用情况无相关性。这可能是由于CAP分级的精确性和细节上的欠缺或该研究样本量限制,未显示出其与3个变量之间的关系。SIR不适用于评估语后聋患者人工耳蜗植人后的言语状况。 相似文献

目的研究不同语速和耳语式的言语是否会影响人工耳蜗植入者的言语识别效果。方法在本研究中,分别对一组人工耳蜗植入者和一组听力正常者进行以下4种不同说话方式的言语识别率测试:慢速言语、常速言语、快速言语和耳语。测试时,人工耳蜗植入者聆听由扬声器播放的未经处理的言语声,正常受试者聆听经4通道人工耳蜗处理的言语声,二者使用相同的原始测试材料。结果人工耳蜗植入组与正常对照组对4种不同说话方式的言语识别结果相似,当说话语速增加时言语识别率逐渐下降,耳语的识别率最差,对于人工耳蜗植入者来说快速言语的识别率显著低于慢速言语识别率。结论人工耳蜗植入者言语识别效果会随着所聆听言语的语速增加而降低,并且聆听耳语式的言语对人工耳蜗植入者来说是非常困难的。 相似文献

Objectives: The goal of this study is to investigate whether prior exposure to reverberant listening environment improves speech intelligibility of adult cochlear implant (CI) users.Methods: Six adult CI users participated in this study. Speech intelligibility was measured in five different simulated reverberant listening environments with two different speech corpuses. Within each listening environment, prior exposure was varied by either having the same environment across all trials (blocked presentation) or having different environment from trial to trial (unblocked).Results: Speech intelligibility decreased as reverberation time increased. Although substantial individual variability was observed, all CI listeners showed an increase in the blocked presentation condition as compared to the unblocked presentation condition for both speech corpuses.Conclusion: Prior listening exposure to a reverberant listening environment improves speech intelligibility in adult CI listeners. Further research is required to understand the underlying mechanism of adaptation to listening environment. 相似文献

Objectives
To document academic achievements and classroom performance in 35 Mandarin-speaking, congenital/pre-lingual, deafened children who used cochlear implants (CIs) for 5–11 years. The possible associated factors were also analyzed.Study design
Cross-sectional case series.Methods
Standardized Chinese literacy ability and mathematics tests were administered to evaluate the academic achievement of these children. Raw scores derived from both literacy ability and mathematics tests were compared with normative data from children with normal hearing (NH). A modified Mandarin edition of the Screening Instrument for Targeting Educational Risk (SIFTER) and a Regular School Adjustment Scale (RSAS) for students with hearing impairments filled out by regular classroom teachers were used to assess the children's classroom performances.Results
The mean standard T-scores for Chinese literacy ability and mathematics ability were 48.6 and 50.3 (NORM = 50 ± 10), respectively. A total of 85.7% of children with CIs scored within or above the normal range of their age-matched hearing peers in Chinese literacy ability, and 82.9% were within normal ranges in mathematics ability. The SIFTER results showed that 45.7% failure was noted on the communication subscale, and the RSAS also indicated 40% of CI students to have communication problems. The academic subscale scores on the SIFTER were associated with the children's Chinese literacy abilities. The Verbal Comprehension Index (VCI) of the Wechsler IQ test IV was related to the children's mathematics abilities.Conclusions
The academic achievements of Mandarin-speaking children who receive CIs from a young age and are integrated into mainstream elementary school system appear to fall within the normal range of their age-matched hearing counterparts after 5–11 years of use. This study strongly suggests the need for future ongoing support for these children in communication field. 相似文献10.
A Danish speech intelligibility test for assessing the speech recognition threshold in noise (SRTN) has been developed. The test consists of 180 sentences distributed in 18 phonetically balanced lists. The sentences are based on an open word-set and represent everyday language. The sentences were equalized with respect to intelligibility to ensure uniform SRTN assessments with all lists. In contrast to several previously developed tests such as the hearing in noise test (HINT) where the equalization is based on scored (objective) measures of word intelligibility, the present test used an equalization method based on subjective assessments of the sentences. The new equalization method is shown to create lists with less variance between the SRTNs than the traditional method. The number of sentence levels included in the SRTN calculation was also evaluated and differs from previous tests. The test was verified with 14 normal-hearing listeners; the overall SRTN lies at a signal-to-noise ratio of ?3.15 dB with a standard deviation of 1.0 dB. The list-SRTNs deviate less than 0.5 dB from the overall mean. 相似文献

The current study was undertaken to investigate the impact of speech motor issues on the speech intelligibility of children with moderate to severe speech sound disorders (SSD) within the context of the PROMPT intervention approach. The word-level Children's Speech Intelligibility Measure (CSIM), the sentence-level Beginner's Intelligibility Test (BIT) and tests of speech motor control and articulation proficiency were administered to 12 children (3:11 to 6:7 years) before and after PROMPT therapy. PROMPT treatment was provided for 45 min twice a week for 8 weeks. Twenty-four naïve adult listeners aged 22–46 years judged the intelligibility of the words and sentences. For CSIM, each time a recorded word was played to the listeners they were asked to look at a list of 12 words (multiple-choice format) and circle the word while for BIT sentences, the listeners were asked to write down everything they heard. Words correctly circled (CSIM) or transcribed (BIT) were averaged across three naïve judges to calculate percentage speech intelligibility. Speech intelligibility at both the word and sentence level was significantly correlated with speech motor control, but not articulatory proficiency. Further, the severity of speech motor planning and sequencing issues may potentially be a limiting factor in connected speech intelligibility and highlights the need to target these issues early and directly in treatment. 相似文献

Objective
The primary purpose of the current study was to evaluate early prelingual auditory development (EPLAD) and early speech perception longitudinally over the first year after cochlear implantation in Mandarin-speaking pediatric cochlear implant (CI) recipients. Outcome measures were designed to allow comparisons of outcomes with those of English-speaking pediatric CI recipients reported in previous research.Method
A hierarchical outcome assessment battery designed to measure EPLAD and early speech perception was used to evaluate 39 pediatric CI recipients implanted between the ages of 1 and 6 years at baseline and 3, 6, and 12 months after implantation. The battery consists of the Mandarin Infant-Toddler Meaningful Auditory Integration Scale (ITMAIS), the Mandarin Early Speech Perception (MESP) test, and the Mandarin Pediatric Speech Intelligibility (MPSI) test. The effects of age at implantation, duration of pre-implant hearing aid use, and Mandarin dialect exposure on performance were evaluated. EPLAD results were compared with the normal developmental trajectory and with results for English-speaking pediatric CI recipients. MESP and MPSI measures of early speech perception were compared with results for English-speaking recipients obtained with comparable measures.Results
EPLAD, as measured with the ITMAIS/MAIS, was comparable in Mandarin- and English-speaking pediatric CI recipients. Both groups exceeded the normal developmental trajectory when hearing age in CI recipients and chronological age in normal were equated. Evidence of significant EPLAD during pre-implant hearing aid use was observed; although at a more gradual rate than after implantation. Early development of speech perception, as measures with the MESP and MPSI tests, was also comparable for Mandarin- and English-speaking CI recipients throughout the first 12 months after implantation. Both Mandarin dialect exposure and the duration of pre-implant hearing aid use significantly affected measures of early speech perception during this time period.Conclusions
EPLAD and early speech perception exhibited similar patterns of improvement during the first 12 months after early cochlear implantation. The duration of pre-implant hearing aid use had a significant positive effect on both categories of outcome measures. Consistent post-implant EPLAD trajectories and early speech perception results provide objective evidence that can guide best practices in early intervention protocols. 相似文献17.

Objectives: The purpose of this study was to compare performance in the areas of verbal working memory (VWM), vocabulary skills, and speech intelligibility between children with cochlear implants (CIs) and children with typical development (TD). The correlations between participant variables and the scores of children with CIs in VWM and the measures of language were examined. Also, it was important to identify which variables predict VWM in children with CIs.Methods: A total of 59 children participated in this study with the study group being comprised of 31 children who had received a CI and the control group being comprised of 28 children with TD. The assessment techniques utilized in this study were the backward digit span (BDS), non-word repetition, speech intelligibility, and vocabulary skills.Results: The study results revealed significant differences in the non-word repetition, speech intelligibility, and vocabulary tasks. The results all favored the typically developing children while the findings for the BDS were equal for both groups.Discussion: In children with CIs the results for VWM observed in this study are believed to be related to the modality of assessment presentation, prior vocabulary knowledge, and familiarity with the presented material. The results from this study also revealed that the variables which predicted VWM in children with CIs were speech perception, duration of CI use, and vocabulary knowledge. 相似文献

Introduction: The National Institute of Health and Care Excellence (NICE) has derived candidacy guidelines for cochlear implants in the UK based on audiometric thresholds (90 dB HL or above at 2 and 4 kHz; hereafter referred to as the 90 dB HL criteria). Recent research has proposed that these criteria should be changed to 80 dB HL at 2 and 4 kHz (hereafter referred to as the 80 dB HL criteria) in the ear to be implanted.Methods: In this study, we analysed aided SII scores derived for different hearing loss profiles falling within the current 90 dB HL criteria and equivalent profiles falling within the new 80 dB HL criteria.Results: The aided SII scores demonstrated that the majority of potential hearing configurations falling within the new proposed 80 dB HL criteria have aided SII values of less than 0.65 (a recommended cut-off point below which there is not sufficient audibility to receive adequate benefit through hearing aids).Conclusions: This supports the proposed change to the 80 dB HL criterion level and also highlights the additional value of the SII score in supporting candidacy decisions for CI, especially for borderline candidates. 相似文献
