Purpose: This study examines whether there are differences in the auditory perceptual evaluation of speech produced by children according to the listener’s clinical experience and seeks to find acoustic correlates. Methods: Fifteen speech-language pathologists (SLPs) and 15 students listened to Korean liquids produced by children aged 4 to 6 years and assessed them using a 5-point Likert scale. The relationship between auditory perceptual evaluation and acoustic variables was analyzed. Results: First, there is a difference in auditory perception scores between laterals and flaps at different ages within 4 to 6 years, and there is a difference in auditory perception scores depending on the vowel environment. Second, the SLP group’s auditory-perceptual evaluation was consistent with the child’s general laterals and flaps development pattern, while the student group’s auditory-perceptual evaluation differed from the laterals and flaps development. Third, in the regression analysis, a higher spectral slope was associated with higher auditory perceptual evaluation in the SLP’s data. Conclusion: It was confirmed that clinical experience plays a quite important role in auditory perceptual evaluation. However, various follow-up studies are needed to enhance the accuracy of these evaluations.

The purpose of this study was to analyze research trends in Korea related to dysarthria according to the speech production mechanism and to present the basis for evaluation and intervention according to the speech production mechanism of dysarthric patients with acute brain injury. Through a search engine, articles published in domestic journals were searched. A total of 43 papers were selected from the searched documents and analyzed according to the year, research subject, and research task. First, in the annual analysis, it was found that research on articulation was conducted most actively among the speech production mechanisms. Second, it can be seen that a number of studies have been conducted on spastic and flaccid types, and mild degree in terms of disorder type and severity, respectively. Third, in terms of speech production units, phonemes and syllable units were used for evaluating respiration and vocalization mechanisms. Sentence and paragraph units were used for the prosody mechanism. These results might be used for the fundamental data to establish the most suitable evaluation methods and intervention plans for patients with dysarthria in clinical and research fields.

Purpose: This study aimed to confirm the characteristics of auditory working memory in typically developing children and children with specific language impairment, considering to the listening environment. We also examined differences in the sub-domains of the auditory working memory task, including digit span, competing language processing tasks, blank filling in continuous words, and a single processing load condition task. Methods: The study included a total of 40 children: 20 children with specific language impaired and 20 typically developing children aged 4 to 5 years old living in Busan and Gyeongnam. To examine potential differences in auditory working memory based on listening environments and groups, the auditory working memory task was conducted in both noisy and quiet environments. Results: Children with specific language impairment showed statistically significantly lower auditory working memory than typically developing children, regardless of the presence of noise. In addition, typically developing children performed better noisy environments compared to quiet ones, whereas children with specific language impairment did not show differences in performance depending on the listening environment. Conclusion: The results of this study suggest that effective language intervention for children with specific language impairment can be provided if auditory working memory is checked and systematically provided for each sub-domain of auditory working memory. For typically developing children, studying in a noisy environment may improve academic ability and attention.

This study analyzes the utilization of online-based auditory training content by individuals aged 70 and above, who are the primary users of auditory training programs. Additionally, we explore effective methodologies for online-based auditory training programs by investigating the impact of differences in auditory training content on training outcomes. Two elderly individuals, one female and one male, wearing hearing aids, participated in this study. We assessed speech perception in noise at 5 dB SNR before and after auditory training. They completed a listening effort questionnaire and attended a total of 20 auditory training sessions over 7 weeks. During the training period, they maintained a “training diary” three times a week. We conducted interviews with the two audiologists who provided auditory training to objectively analyze the diary survey results. Both hearing aid users demonstrated improved speech perception in noise scores and reduced listening effort. The analysis of auditory training experiences categorized them into three types: ‘emotion-stimulating,’ ‘information-generating,’ and ‘participatory.’ These categories informed the development of strategies for online auditory training content, including: 1) personalized auditory training content using artificial intelligence, 2) integration of auditory training into senior education programs, and 3) creation of interactive online auditory rehabilitation content using bidirectional technology. The study emphasizes the need for continuous development of interactive content tailored to the demographic and lifestyle characteristics of the participants. In the context of online-based auditory training, individualized programs, such as group training and professional-led programs, are essential. Further studies are required to determine whether training outcomes can be enhanced through experience-based content.

The purpose of this study is to understand self-reported hearing difficulties and hearing aid uptake with people perceiving hearing difficulties in Korea. The study investigated a total of 788 adults (mean age 67 years) with self-reported hearing difficulties during the eighth survey of Korean National Health and Nutrition Examination. The data included otolaryngology survey, pure tone hearing thresholds, and surveys on quality of life and mental health. People perceiving hearing difficulties showed reduced hearing thresholds. The prevalence of hearing aid uptake was 12.8% of people with self-reported hearing difficulties. People with mild and severe hearing difficulties showed 4.8% and 35.5% of prevalence in hearing aid uptake, respectively. The uptake of hearing aids in Korea was found to be very low. Subjective self-evaluation of hearing difficulties can be used as an indexing tool of hearing loss.

Purpose: This study investigated the tinnitus relief effect of the stimulation listening method in sound therapy. Methods: The participants were randomly divided into two groups: 16 in the continuous listening group and 15 in the intermittent listening group. The participants listened to broad-band noise at the mixing point level for 3 months, either continuously for 2 hours or intermittently 4 hours for 30 minutes, depending on the group allocation. The results of this study were confirmed by measuring scores through the Korean version of the Tinnitus Primary Function Questionnaire (K-TPFQ) and visual analog scale (VAS) for tinnitus loudness and annoyance at pretreatment and at 1, 2, and 3 months follow-ups. Results: Average scores of the K-TPFQ and VAS for tinnitus loudness and annoyance significantly improved with the duration of sound therapy in both the continuous listening and intermittent listening groups (p < 0.05). However, there was no difference between the two groups regarding the stimulation listening method in sound therapy, and no significant interaction effects were confirmed. Conclusion: The method of listening to the sound therapy continuously for 2 hours and the method of listening intermittently for 30 minutes had similar tinnitus relief effects.

The goal of auditory training is to improve comprehensive listening skills for the hearing impaired. Listening ability does not simply mean the level of recognizing speech sounds by distinguishing them, but also includes predicting the speaker’s intention according to the situation and context, and responding appropriately. Speakers create their utterances in a way that tries to convey their intended meaning with minimal effort under the economic principle, resulting in concise expressions that are contingent on the context and situation. Therefore, correct listening education and training should be structured to have the ability to fully understand the omitted implications and implications contained in the speaker’s speech. For auditory training for those with hearing impaired to be effective, speech perception training must extend beyond simple phonological perception by integrating one's background knowledge and communication schema within various situations and contexts. Therefore, auditory training using idiomatic expressions plays a crucial role in improving the ability to construct discourse meanings as well as comprehend the speech patterns encountered by hearing-impaired individuals in their daily communication. It is necessary to select idiomatic expressions frequently encountered in real-world communication situations and conduct auditory training by presenting transparent expressions to opaque expressions, facilitating the hearing-impaired's grasp of meaning with ease.

Purpose: The Spatial Hearing Questionnaire (SHQ) is a self-report subjective questionnaire that includes eight subscales, including “understanding of male, female, and child’s voice”, “music”, “localization”, “speech understanding in quiet, noise-front, and noise-separate situations”. The aim of this study was to examine the validity and reliability of the Korean version of the SHQ (K-SHQ) in cochlear implant (CI) users. Methods: Fifty-two adult CI users participated in this study. Internal consistency and test-retest reliability of the K-SHQ were evaluated. Concurrent validity was identified by comparing the K-SHQ responses with the “spatial hearing” subscale scores from the Korean version of the Speech, Spatial, and Qualities of Hearing Scale (K-SSQ). We also examined the construct validity of the K-SHQ through an exploratory factor analysis. Results: Overall, the greatest difficulties were obtained from the subscale of “localization”, with the least difficulties in the subscale of “speech in quiet”. Both internal consistency and test-retest reliability were adequate for CI users based on all 24 items and the 8-subscale responses of the K-SHQ. The “localization” subscale responses of the K-SHQ were significantly correlated with the “spatial hearing”subscale responses of the K-SSQ, demonstrating a good concurrent validity in relation to localization performance. The results of the exploratory factor analysis showed that two factors, “speech understanding” and “localization”, explained 73.2% of the variance. Conclusion: The K-SHQ showed satisfactory reliability and validity in evaluating speech understanding as well as spatial hearing abilities in cochlear implant users, especially in complex listening situations.

Purpose: This study aimed to determine whether auditory spatial training with real-life environmental noise would improve the speech-in-noise intelligibility of hearing-impaired children. Methods: Thirteen children with hearing loss participated in this study. We conducted an 8-week in-laboratory auditory spatial training. During the training, the target sentence and pre-recorded real-life environmental noise were spatially separated by 90°, and uncertainty about the location of the target and noise was given. To evaluate the efficacy of the training, sentence recognition with fluctuating and non-fluctuating noises was measured in a free sound-field condition, where the speech and noise sources were spatially separated and also co-located. The pre-training tests of sentence-in-noise recognition were performed twice with an interval of 6 weeks. The sentence-in-noise recognition test was also measured right after the 8-week training (post-training test) as well as 1 month after the completion of the training (retention test). In addition to the objective tests, the parents completed a subjective questionnaire on auditory behavior in everyday life before and after training. Results: There were no significant differences between the results of the two pre-training tests. The auditory spatial training significantly enhanced sentence-in-noise recognition in both spatially separated and co-located conditions at all signal-to-noise ratios, and the training efficacy was maintained until 1 month after the completion of the training. The parental subjective responses also showed positive changes after the training. Conclusion: An 8-week auditory spatial training could effectively enhance the speech-in-noise intelligibility of hearing-impaired children in spatialized as well as non-spatialized conditions.

This study was conducted to use it as basic information to suggest the necessity and program for self-regulation that can properly maintain voice according to the degree of hearing loss. For this purpose, twenty-six men in their fifties were classified according to the degree of hearing loss, and multidimensional voice program (MDVP) (F0, jitter, shimmer, noise to harmonics ratio [NHR]), cepstrum (cepstral peak prominence [CPP], low/high spectral ratio [L/H ratio], mean CPP F0, cepstral/spectral index of dysphonia [CSID]) and vocal fatigue index (fatigue, physical, rest, total) were performed and analyzed. The more severe the degree of hearing loss, the higher the F0 and CSID, and the lower the L/H ratio, the overall quality of the voice deteriorated. Normal-mild hearing loss group indicated a positive correlation between mean CPP F0 and fatigue, rest and total, and negative correlation between CPP and rest. In severe-profound group, F0 and rest showed a negative correlation, and shimmer and rest showed a positive correlation. Through the analysis of vowel and connected speech, it was found that the more severe the degree of hearing loss, the higher the F0 in vowel phonation, the lower the L/H ratio and the higher the CSID, and the lower the overall sound quality. In addition, it was observed that that the more severe the hearing loss, the higher the fatigue level of the hearing-loss person who speaks due to severe voice misuse and abuse. Therefore, auditory rehabilitation patients with hearing loss optimal voice production, and voice rehabilitation programs that use proper voices should be supported.

Through the analysis of vowel and connected speech, it was found that the more severe the degree of hearing loss, the higher the F0 in vowel phonation, the lower the L/H ratio and the higher the CSID, and the lower the overall sound quality. In addition, it was observed that that the more severe the hearing loss, the higher the fatigue level of the hearing-loss person who speaks due to severe voice misuse and abuse. Therefore, auditory rehabilitation patients with hearing loss optimal voice production, and voice rehabilitation programs that use proper voices should be supported.","PeriodicalId":36841,"journal":{"name":"Audiology and Speech Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85902205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
