摘要

近年来,关于远程练习的实用性和有效性已有报道。对腭裂患者的补偿发音治疗是以感知识别为基础的。使用视频会议平台进行远程练习会导致语音信号失真,影响听觉感知。本研究旨在从声学角度检查语音信号失真,并确定最佳视频会议平台,以及能辨别出与面对面交流质量相同的音素。ATR503 包含 50 个音素平衡的日语语音句子,被用作参考语料库。将四种视频会议平台(Zoom、Cisco Webex、Skype 和 Google Meet)和五种设备(iPhone、Android、iPad Air、Windows 和 MacBook Pro)作为传输条件,用对数频谱失真(LSD)这一客观指标来检测语音信号失真。采用 Tukey's 检验来评估辅音失真程度与发声(无声和有声)、发音部位(双唇、齿龈、齿龈-腭、腭、天鹅绒、唇-声门和喉音)和发音方式(塞音、摩擦音、副元音、拍音或瓣音、鼻音和近似音)的关系。在统计上有显著差异的是,声母、双唇辅音、唇瓣辅音、鼻音辅音和犁音辅音的失真较小。相比之下,无嗓辅音、齿龈腭辅音、擦音辅音和塞音辅音的失真较大。在视频会议平台中,Google Meet 的失真最小,而在设备中,MacBook 的失真最小。这项研究为使用合适的视频会议平台和设备进行远程练习的策略提供了重要启示,并为具有声学补偿发音的腭裂患者提供了有用的设置。

Acoustic evaluation of voice signal distortion by videoconferencing platforms and devices used in telepractice for cleft palate

Acoustic evaluation of voice signal distortion by videoconferencing platforms and devices used in telepractice for cleft palate

The usefulness and effectiveness of telepractice have been reported in recent years. Treatment of cleft palate patients with compensatory articulation is based on perceptual identification. Telepractice using videoconferencing platforms causes voice signal distortion and impacts auditory-perceptual perception. This study aimed acoustically examine voice signal distortion and determine the optimal videoconferencing platforms, in addition to the phonemes that can be discriminated with the same quality as in face-to-face interactions. ATR503 with 50 phoneme-balanced Japanese speech sentences was used as a reference corpus. Four videoconferencing platforms, —Zoom, Cisco Webex, Skype, and Google Meet, —and five devices, —iPhone, Android, iPad Air, Windows, and MacBook Pro were used as transmission conditions to examine voice signal distortions with the objective measure log-spectral distortion (LSD). Tukey's test was conducted to evaluate the degree of consonant distortion related to voicings (voiceless and voiced), places of articulation (bilabial, alveolar, alveolo-palatal, palatal, velar, labial-velar, and glottal), and manners of articulation (plosive, fricative, affricate, tap or flap, nasal, and approximant). With statistically significant differences, voiced, bilabial, labial-velar, nasal, and plosive consonants exhibited smaller distortions. In contrast, voiceless, alveolo-palatal, fricative, and affricate consonants exhibited larger distortions. Google Meet exhibited the lowest distortion among videoconferencing platforms and MacBook exhibited the lowest distortion among devices. This study provides significant insights into the telepractice strategies with the appropriate videoconferencing platform and device, and useful settings for cleft palate patients with compensatory articulations with respect to acoustics.
