Two experiments were designed to evaluate a prototype device developed to provide a visual presentation of speech sounds as a potential assistive device for hearing-imparied persons. In the 1st experiment, the ability of adults with unimpaired hearing to recognize the visual patterns of 3 vowels spoken by 3 different speakers was assessed, and in the 2nd experiment, visual and auditory distinctiveness of the 3 vowels was compared. Results showed that subjects received different speech information from the Visual Speech Spectrum Analyzer (VISSA) and the normal auditory system; however, differences were judged minor. The device has potential as a speech therapy aid and may prove helpful to hearing imparied persons.
设计了两项实验来评估一种原型设备，该设备旨在将语音以视觉形式呈现，作为听力受损者的一种潜在辅助设备。在第一个实验中，评估了听力正常的成年人识别由3位不同说话者说出的3个元音的视觉模式的能力，在第二个实验中，比较了这3个元音的视觉和听觉特征。结果表明，受试者从视觉语音频谱分析仪（VISSA）和正常听觉系统获得了不同的语音信息；然而，差异被判定为较小。该设备有作为言语治疗辅助工具的潜力，可能对听力受损者有帮助。
