概括
这项研究使用光环摄影来分析语音治疗练习期间的声音攻击. 结果显示,各种半封闭声道练习 (SOVTE) 的声开放率 (OQ) 不同,这表明定制的SOVTE可以提高语音质量.
科学领域:
- 耳鼻喉科和语音科学 耳鼻喉科和语音科学
- 语音的生物力学和声学
背景情况:
- 对失声症的治疗缺乏关于最有效的语音治疗技术的明确证据.
- 语音攻击是发声的关键组成部分,被认为是发声障碍的原因.
- 摄影声学 (PGG) 提供了一种方法,可以客观地评估发音过程中的声动态.
研究的目的:
- 为了研究不同类型的声音攻击对声动态的影响.
- 在各种半封闭声道练习 (SOVTE) 中分析声开放率 (OQ).
- 为了比较PGG衍生的OQ参数跨自然,硬和软语音发声,以及不同的SOVTE.
主要方法:
- 18名健康成年人 (10名男性,8名女性) 参与了这项研究.
- 摄影声波 (PGG) 被用来记录前五个声波.
- 测量包括自然语音,硬攻击,软攻击和SOVTE (声,6mm和13mm管声,唇),重点关注25%的声开放系数 (OQ).
主要成果:
- 在25%的OQ中没有观察到与性别相关的显著差异.
- 在第一个波中,强烈的声音攻击显示了明显较低的25%的OQ,与软攻击,舌头和唇相比.
- 软攻击比音,6毫米管声和唇音高出25%的OQ. 不同的SOVTEs导致25%的OQ值变化,13mm管声学显示OQ值高于6mm. 语音开始的OQ在SOVTE技术和声波之间有所不同.
结论:
- 选择半遮蔽声道练习 (SOVTE) 可以显著影响声动态.
- 根据个体患者的需求量身定制SOVTE选择可能会提高语音治疗的结果.
- 建议进行进一步的研究,以验证这些研究结果在患有听力障碍的患者中.

Assessment of Airway, Skin Color, and Use of Accessory Muscles
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Modeling in Therapy
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
