Vowel identification was tested in quiet, noise, and reverberation with 20 normal-hearing subjects and 20 hearing-impaired subjects. Stimuli were 15 English vowels spoken in a /b-t/context by six male talkers. Each talker produced five tokens of each vowel. In quiet, all stimuli were identified by two judges as the intended targets. The stimuli were degraded by reverberation or speech-spectrum noise. Vowel identification scores depended upon talker, listening condition, and subject type. The relationship between identification errors and spectral details of the vowels is discussed.
对20名听力正常的受试者和20名听力受损的受试者在安静、噪声和混响环境下进行了元音识别测试。刺激音是由6名男性说话者在/b-t/语境中说出的15个英语元音。每个说话者为每个元音生成5个样本。在安静环境中,两名评判员将所有刺激音都识别为预期的目标。刺激音因混响或语音频谱噪声而退化。元音识别分数取决于说话者、聆听条件和受试者类型。文中讨论了识别错误与元音频谱细节之间的关系。
