摘要

虽然电话频段(0.3-3 kHz)为语音识别提供了足够的信息,但非电话频段(3 kHz)的贡献尚不清楚。为了研究非电话频段的贡献,我们使用辅音、元音和句子对语音清晰度和通话者识别进行了评估。非耳机频段对辅音(76.0%)和句子(77.4%)的可懂度相对较好,但对元音(11.5%)的可懂度较差。非耳机频段只在句子(74.5%)、元音(45.8%)和辅音(10.8%)方面支持良好的说话者识别。此外,非耳机频段无法在噪音中产生令人满意的句子级语音清晰度,这表明全频段接入在实际听力中的重要性。

Speech intelligibility and talker identification with non-telephone frequencies.

Although the telephone band (0.3-3 kHz) provides sufficient information for speech recognition, the contribution of the non-telephone band (<0.3 and >3 kHz) is unclear. To investigate its contribution, speech intelligibility and talker identification were evaluated using consonants, vowels, and sentences. The non-telephone band produced relatively good intelligibility for consonants (76.0%) and sentences (77.4%), but not vowels (11.5%). The non-telephone band supported good talker identification only with sentences (74.5%), but not vowels (45.8%) or consonants (10.8%). Furthermore, the non-telephone band cannot produce satisfactory speech intelligibility in noise at the sentence level, suggesting the importance of full-band access in realistic listening.
