Objective: The present study had two objectives: (1) to investigate differences in voice parameters between teachers with and without self-reported voice disorders and (2) to find differences in voice parameters between teachers and healthcare workers without self-reported voice disorders.

Method: Three respondents' groups were formed: teachers with self-reported voice disorders (mean age, 47 years; range, 34-60 years), teachers without self-reported voice disorders (46; 27-64), and healthcare workers without self-reported voice disorders (45; 31-63). All participants were women. Maximum Phonation Time (MPT), fundamental frequency (F0), jitter, shimmer, frequency and intensity range, Dysphonia Severity Index (DSI), Voice Handicap Index-30 (VHI), and perceived stress (PSS) were assessed in respondents.

Results: Twenty-nine percent of teachers noted two or more vocal symptoms daily or weekly. Teachers with self-reported voice disorders had a higher degree of perceived stress (18 vs. 13, p = .009), higher score on the VHI (25 vs. 13, p = .001), and lower score on the DSI (2.65 vs. 3.21, p = .037), than teachers without self-reported voice disorders. The VHI-30 score of 15 points could be a cut off value describing voice disorders in female teachers. Differences between teachers and health care workers without self-reported voice disorders were found in MPT (p = .001), F0 (p = .012), jitter (p = .009), DSI (p = .023), and the perceived stress score (p = .041).

Conclusions: The teaching profession can influence the voice, and the presence of psycho-emotional factors can lead to the development of voice disorders in teachers.

目的:本研究有两个目的:(1)调查有和没有自述语音障碍的教师的语音参数差异;(2)发现没有自述语音障碍的教师和医护人员的语音参数差异。方法:将被调查者分为三组:自述有语音障碍的教师(平均年龄47岁;范围,34-60岁),没有自我报告语音障碍的教师(46;27-64),以及没有自我报告声音障碍的卫生保健工作者(45;31 - 63)。所有的参与者都是女性。评估应答者的最大发声时间(MPT)、基频(F0)、抖动、闪烁、频率和强度范围、语音障碍严重程度指数(DSI)、语音障碍指数-30 (VHI)和感知压力(PSS)。结果:29%的教师每天或每周发现两种或两种以上的声音症状。自我报告有语音障碍的教师比没有自我报告语音障碍的教师有更高的感知压力程度(18比13,p = 0.009),更高的VHI得分(25比13,p = 0.001),更低的DSI得分(2.65比3.21,p = 0.037)。15分的VHI-30分可能是描述女教师声音障碍的临界值。在MPT (p = .001)、F0 (p = .012)、抖动(p = .009)、DSI (p = .023)和感知压力得分(p = .041)方面,教师与无自我报告语音障碍的医护人员存在差异。结论:教师职业对语音有影响,心理情绪因素的存在可导致教师语音障碍的发展。

Background: Twang quality is a bright, piercing quality often produced in contemporary pop/rock/country music, musical theatre singing, and character voices. Despite its potential application to voice therapy and singing pedagogy, limited information is available regarding the exact physiologic underpinnings of twang quality. The purpose of this study was to provide quantitative information regarding three-dimensional (3D) vocal tract configurations of twang quality using magnetic resonance imaging (MRI).

Methods: Two participants, with professional singing and pedagogy experience in a variety of singing styles, sustained twang and speech quality on vowel /i/ while lying supine in the MRI scanner. Vocal tract measures included larynx height and velar height in the midsagittal view as well as lateral pharyngeal width, anteroposterior pharyngeal (AP) width, and pharyngeal area in the axial view.

Results: When compared to speech /i/, participants produced twang with a smaller pharyngeal area with significant narrowing in the lateral dimension, a slightly elevated laryngeal position, and closed VP port. Of note, Participant 1 also demonstrated significant pharyngeal narrowing in the AP dimension at the oropharyngeal level.

Conclusion: The results are consistent with some aspects of previous descriptions of twang but provide further clarification regarding physiologic underpinnings of twang quality for therapeutic and pedagogic application.

背景:Twang音质是一种明亮、刺耳的音质,经常出现在当代流行/摇滚/乡村音乐、音乐剧演唱和人物声音中。尽管它在声音治疗和歌唱教育学方面有潜在的应用,但关于鼻音质量的确切生理基础的信息有限。本研究的目的是利用磁共振成像(MRI)提供有关鼻音质量的三维(3D)声道结构的定量信息。方法:2名具有专业歌唱和教学经验的受试者,在仰卧的情况下,对各种唱法、元音/i/持续的鼻音和语音质量进行MRI扫描。声道测量包括中矢状位的喉高和腭高,以及轴位的咽外侧宽度,咽前后(AP)宽度和咽面积。结果:与语音/i/相比,参与者发出的鼻音具有较小的咽面积,显著的侧缩,喉部位置略微升高,VP端口关闭。值得注意的是,参与者1在口咽水平的AP维度也表现出明显的咽狭窄。结论:本研究结果与前人对鼻音的描述一致,并进一步阐明了鼻音质量的生理学基础,为临床和教学应用提供了依据。

Objective: The objective is to produce a short instrument for measuring the subjectively experienced articulation handicap, i.e. the extent to which physical, functional, and emotional handicaps caused by a physical deficit are subjectively experienced.

Methods: The items for the short instrument were selected from the 30 items of the Articulation Handicap Index (AHI) by removing items on the basis of item-total correlations using data from 113 cancer survivors. Reliability and validity of the sum score of the corresponding item selection were used for determining the optimal item selection. This optimal item selection was compared with the AHI in an RCT with patients undergoing phoniatric routine diagnostics.

Results: With only 12 items left, the measurement instrument was still as reliable and valid as the AHI. With less than 12 items, reliability and validity decreased. In the RCT between the AHI (n = 41) and the 12-item selection (n = 40), reliability and validity of both instruments were the same, but processing times differed (AHI; 3.84 min; 12-item selection: 2.02 min).

Conclusion: The 12-item selection, further referred to as the Articulation Handicap Scale with 12 items (AHS-12), provides nearly as much information as the original AHI.

目的:目的是制作一个简短的工具来测量主观体验的发音障碍,即主观体验由身体缺陷引起的身体,功能和情感障碍的程度。方法:使用113例癌症幸存者的资料,从发音障碍指数(AHI)的30个项目中,根据项目总量相关性剔除项目,选择短仪项目。采用相应项目选择的总得分的信度和效度来确定最优项目选择。该最佳项目选择与接受语音常规诊断的患者的随机对照试验中的AHI进行了比较。结果:仅剩12项,测量仪器仍与AHI量表一样可靠有效。少于12项时,信度和效度下降。在AHI (n = 41)和12项选择(n = 40)的RCT中,两种工具的信度和效度相同,但处理时间不同(AHI;3.84分钟;12项选择:2.02分钟)。结论:12项选择,进一步称为12项发音障碍量表(AHS-12),提供的信息几乎与原来的AHI一样多。

Purpose: At a worldwide level, suicide is a public health problem that, despite displaying downward trends in several areas of the world, in many countries these rates have increased. One of the elements that contributes to its prevention is an early and dynamic evaluation. Due to this, the objective is to determine the association between acoustic parameters of voice and speech (F0, F1, F2, F3, dB, and Jitter) and suicidal ideation arousal amongst some university students from the city of Temuco, Chile.

Methods: Attending to this issue, a cross-sectional design study was conducted through a non-probabilistic sampling of sixty 18- and 19-year-old adolescents from the city of Temuco, that went through an acoustic evaluation of their voice and speech after taking a test to determine suicidal ideation. Afterwards, data were analyzed through IBM SPSS version 23.0 software (IBM SPSS Statistics, Armonk, NY), by means of exploratory, descriptive, and inferential statistics taking the variable's levels of measurements and the types of distributions into account.

Results: The results point out that 30% of the adolescents, from both genders, displayed suicidal ideation. Taking into account the acoustic results of their voice, it is possible to recognize that the fundamental frequency (F0), the formants (F1, F2), and Jitter, are the ones that majorly link to the presence of suicidal ideation, both in women and men (p < .05). The characteristics that describe F3 were only linked to the presence of suicidal ideation in men (p < .05).

Conclusions: It is concluded that the acoustic parameters of voice and speech differ in adolescents with suicidal behavior, opening the possibility of representing a useful tool in the diagnosis of suicide.

目的:在世界范围内,自杀是一个公共卫生问题,尽管世界上一些地区的自杀率呈下降趋势,但在许多国家,自杀率却有所上升。有助于预防这种疾病的因素之一是早期和动态的评价。因此,我们的目标是确定声音和言语的声学参数(F0, F1, F2, F3, dB和Jitter)与智利特木科市一些大学生的自杀意念唤醒之间的关系。方法:针对这一问题,通过对来自特穆科市的60名18岁和19岁的青少年进行非概率抽样进行了横断面设计研究,这些青少年在接受自杀意念测试后对他们的声音和言语进行了声学评估。随后,通过IBM SPSS version 23.0软件(IBM SPSS Statistics, Armonk, NY)对数据进行分析,采用探索性统计、描述性统计和推断性统计的方法,同时考虑变量的测量水平和分布类型。结果:结果指出,30%的青少年(男女均有)表现出自杀意念。考虑到他们声音的声学结果,有可能认识到基本频率(F0),共振峰(F1, F2)和抖动,是与自杀意念存在主要联系的,无论在女性还是男性中(p p)。结论:结论是,有自杀行为的青少年的声音和言语声学参数不同,打开了代表自杀诊断有用工具的可能性。

Objective: Unilateral vocal folds paralysis is a disorder that affects a patient's quality-of-life by disturbing their phonation, breathing, and swallowing activities. This systematic review aimed to estimate the efficacy of voice treatment on the vocal fold motility in adult patients with unilateral vocal folds paralysis.

Methods: PubMed, CINAHL, CENTRAL, and Web of Science were searched for retrospective and prospective cohort, case-control, and cross-sectional with comparative studies with adults that were published between 1 January 2008 to 31 December 2018. After applying the inclusion and exclusion criteria a total of 10 studies containing morpho-functional evaluation results were included in the analysis. Pooled data analysis of the motility of the vocal folds before and after voice therapy allowed inferring about the efficacy of voice therapy intervention in patients with unilateral vocal folds paralysis. A random-effect model was used to estimate the effect size. Publication bias was considered.

Results: The pooled data analysis of the visual-perceptual measures revealed that vocal fold motility improved in 72% (95% CI: 64.0-80.0) of all patients after the therapeutic interventions. The inconsistency index (I2 = 18.35%) of the studies included in this meta-analysis revealed an extremely low heterogeneity. Funnel plot and Cochran's Q test showed no publication bias. The systematic review was limited to only English language articles.

Conclusion: This meta-analysis supports the evidence that voice therapy intervention can have a positive effect on the vocal fold motility, that is, they can improve the glottal gap closure, irrespective of the exercises and techniques used.

目的:单侧声带麻痹是一种通过干扰患者发声、呼吸和吞咽活动而影响患者生活质量的疾病。本系统综述旨在评估嗓音治疗对单侧声带麻痹成人患者声带运动的影响。方法:检索PubMed、CINAHL、CENTRAL和Web of Science,检索2008年1月1日至2018年12月31日发表的成人回顾性和前瞻性队列、病例对照和横断面比较研究。应用纳入和排除标准后,共有10项包含形态功能评价结果的研究被纳入分析。对声音治疗前后声带运动的汇总数据分析,可以推断单侧声带麻痹患者的声音治疗干预效果。采用随机效应模型估计效应大小。考虑发表偏倚。结果:视觉知觉测量的汇总数据分析显示,治疗干预后,所有患者的声带运动改善了72% (95% CI: 64.0-80.0)。本荟萃分析纳入的研究的不一致指数(I2 = 18.35%)显示异质性极低。漏斗图和Cochran’s Q检验显示无发表偏倚。系统评价仅限于英文文章。结论:本荟萃分析支持语音治疗干预对声带运动有积极影响的证据,即无论使用何种练习和技术,它们都可以改善声门间隙关闭。

Aim: The aim of this study was to investigate the voice problems with vocal loading in physicians.

Method: It was planned to have two groups and thirty participants in each group. The participants were surgeon and nonsurgeon, male and female doctors (first group: 15 female +15 male nonsurgeon; second group: 15 female +15 male surgeon). Volunteers were also separated according to the duration of career, patients seen daily and polyclinic days weekly. Visual analog scale (VAS) scores and voice fatigue index (VFI) version 2 were applied. Objective measurements (F0, jitter, shimmer, harmonics-to-noise ratio) of acoustic evaluation according to the same variables were recorded.

Results: There was a statistically significant difference in the number of patients seen daily between the groups (<50 patients/day and >50 patients/day) in terms of VFI parts 1 and 2 averages. There was a statistically significant difference between branches (surgical vs. nonsurgical) in terms of VFI part 1 (p = .034). The tiredness of voice was prominent in the physicians who saw more patients and who had more workdays weekly and who were nonsurgeon (VFI part 1). Physical discomfort was more prominent in physicians whose duration of career was long and whose daily patients were more (VFI part 2) (p < .05).The number of patients seen daily and number of days to work did not affect objective acoustic parameters. Being experienced as year in women and being surgeon decreased the mean shimmer values in objective measurements (p < .05).

Conclusion: Physicians experienced vocal fatigue (VF) in varying degrees according to the differences in working conditions.

目的:本研究的目的是探讨医生的声音负荷问题。方法:拟分为两组,每组30人。参与者包括外科医生和非外科医生,男性和女性医生(第一组:15名女性+15名男性非外科医生;第二组:女15名+男15名)。志愿者也根据工作时间、每日就诊天数和每周就诊天数进行分类。采用视觉模拟量表(VAS)评分和语音疲劳指数(VFI)版本2。根据相同的变量记录声学评价的客观测量值(F0、抖动、闪烁、谐波噪声比)。结果:在VFI第1部分和第2部分的平均值方面,两组之间每天看到的患者数量(50例/天)有统计学意义。就VFI第1部分而言,不同分支(手术与非手术)的差异有统计学意义(p = 0.034)。嗓音疲劳在就诊病人多、每周工作天数多、非外科医师中较为突出(VFI part 1)。身体不适在职业时间长、日常病人多的医师中更为突出(VFI part 2) (p p结论:根据工作条件的不同,医师有不同程度的声音疲劳。

Objective: To report the volumetric measures of the paralyzed vocal fold in patients undergoing injection laryngoplasty.

Material and method: All the medical records of patients with unilateral vocal fold paralysis who had high resolution computerized tomography scan of the neck and chest prior to injection laryngoplasty between October 2015 and May 2018 were included. Volumetric evaluation of the vocal folds was performed by measuring the vocal fold height using coronal images and the vocal fold length and width using axial images.

Results: A total of 21 patients divided into 13 males and 8 females were identified. The mean age was 56.66 ± 20.94 years. The mean volume of the paralyzed vocal fold was significantly smaller than that of the non-paralyzed vocal fold (p < .05). Similarly, the mean length and height of the paralyzed vocal folds were smaller than those of the non-paralyzed vocal folds (p < .05).

Conclusion: Volumetric measurements of the paralyzed vocal fold in comparison to the normal vocal fold in a group of 21 patients with unilateral vocal fold paralysis shows the presence of significant difference between the normal and affected site, and the presence of large inter-subject variation. Information on the volume difference between the two vocal folds may be used to better estimate the amount that needs to be injected in medialization procedures.

目的:报道注射喉成形术患者声带麻痹的体积测量。材料和方法:纳入2015年10月至2018年5月所有单侧声带麻痹患者在注射喉部成形术前进行颈胸部高分辨率计算机断层扫描的病历。通过冠状面图像测量声带高度,轴向图像测量声带长度和宽度,对声带进行体积评估。结果:共鉴定出21例患者,男13例,女8例。平均年龄56.66±20.94岁。结论:21例单侧声带麻痹患者的声带麻痹体积与正常声带体积的比较显示正常部位与受累部位存在显著差异,且存在较大的主体间差异。关于两个声带之间音量差异的信息可以用来更好地估计在麻醉过程中需要注射的量。

Effects of intervention on self-efficacy and text quality in elementary school students' narrative writing. 干预对小学生叙事写作自我效能感和文本质量的影响。
IF 1.1 4区 医学 Q4 AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY Pub Date : 2021-04-01 Epub Date: 2020-01-08 DOI: 10.1080/14015439.2019.1709539

Aim: Self-efficacy for writing is an important motivational factor and considered to predict writing performance. Self-efficacy for narrative writing has been sparsely studied, and few studies focus on the effects of writing intervention on self-efficacy. Additionally, there is a lack of validated measures of self-efficacy for elementary school students. In a previous study, we found that a trained panel rated personal narrative text quality higher for girls than for boys, which led to our aim: to investigate boys' and girls' self-efficacy for narrative writing before and after an intervention, and to explore associations between self-efficacy and text quality.

Methods: An 18-item self-efficacy scale was developed. Fifty-five fifth-grade students (M 11:2 years, SD 3.7 months) filled out the scale before and after a five-lesson observational learning intervention. Self-efficacy was then related to writing performance as measured by holistic text quality ratings.

Results: The students demonstrated strong self-efficacy, which increased significantly post-intervention. Girls and boys demonstrated similar self-efficacy, despite girls' higher text quality. There were moderate correlations between self-efficacy and writing performance pre- and post-intervention.

Conclusions: The results support previous findings of strong self-efficacy at this age. The interaction between writing self-efficacy and performance is complex. Young students may not be able to differentiate between self-efficacy, general writing skills, task performance, and self-regulation. Self-efficacy scales should thus be carefully constructed with respect to age, genre, instruction, and to students' general educational context.

目的:写作自我效能感是影响写作表现的重要动机因素。叙事性写作的自我效能感研究较少,很少有研究关注写作干预对自我效能感的影响。此外,缺乏有效的测量小学生自我效能感的方法。在之前的一项研究中,我们发现经过训练的小组对女孩的个人叙事文本质量的评价高于男孩,这导致了我们的目标:调查男孩和女孩在干预前后的叙事写作自我效能感,并探索自我效能感与文本质量之间的关系。方法:编制18项自我效能感量表。55名五年级学生(男生11.2岁,女生3.7个月)在五课观察学习干预前后填写了量表。然后,自我效能感与写作表现有关,通过整体文本质量评级来衡量。结果:学生自我效能感较强,干预后显著提高。女孩和男孩表现出相似的自我效能感,尽管女孩的文本质量更高。干预前后,自我效能感与写作表现有中度相关。结论:研究结果支持了先前的研究结果,即该年龄段的自我效能感较强。写作自我效能与写作表现之间的相互作用是复杂的。年轻学生可能无法区分自我效能感、一般写作技巧、任务表现和自我调节。因此,自我效能感量表应根据年龄、体裁、教学和学生的一般教育背景精心构建。

Introduction: The duration of the nuclei is a crucial factor for the shift of prelexical to mature speech, since control of duration is closely related with improved speech intelligibility.

Objectives: This work records the suprasegmental feature of duration in infants with normal hearing (NH) compared to those with cochlear implants (CI) based on vocant productions (quasivowels and full vowels).

Materinals and methods: In this longitudinal study, 102 vocant productions were analyzed from cases of congenitally hearing-impaired infants (implantation ages 1:4 and 1:11 years; post-implant ages 0:6 months and 1:3 years) who were matched with three NH infants of similar hearing experience (ages 0:8-0:11 months). Current methodology analyzes vocants using a combination of acoustical and auditory analyses. Vegetative data or reflexive sounds were excluded. Participants had had unknown deafness etiology and no other disabilities. Duration was measured using wideband spectrographic analysis, from voice onset to the loss of audible signal and the decrease of higher formant's energy.

Results: The results showed that the mean vocant duration of young CI users was longer, compared to hearing matched peers during the first six months after cochlear implantation.

Conclusions: This recorded weakness for CI users' speech production is a challenge for future work in speech processing strategies. This is the first study measuring production of vocants during the pre-linguistic stage in CI recipients.

核的持续时间是词汇前语言向成熟语言转变的关键因素,因为对持续时间的控制与语言可理解性的提高密切相关。目的:本研究记录了正常听力婴儿(NH)与人工耳蜗婴儿(CI)基于元音产生(准元音和完整元音)的持续时间的超节段特征。材料与方法:在本纵向研究中,分析了102例先天性听障婴儿(植入年龄1:4和1:11岁;植入后年龄分别为0∶6个月和1∶3岁),与3名听力相近的新生儿(0∶8-0∶11个月)配对。目前的方法是结合声学和听觉分析来分析发声者。排除植物性数据或反射性声音。参与者耳聋病因不明,无其他残疾。使用宽带频谱分析测量从声音开始到可听信号丧失和高峰能量下降的持续时间。结果:结果显示,在人工耳蜗植入后的前6个月,年轻人工耳蜗使用者的平均发声持续时间比听力匹配的同龄人更长。结论:CI用户语音产生的这一记录弱点是语音处理策略未来工作的挑战。这是第一个在CI接受者的前语言阶段测量发声的研究。
