| 摘 要： | 在实验室条件下测量了不同频带范围、不同信噪比条件时的语言清晰度和STI—PA，分析了清晰度，STI-PA与信噪比的关系，并根据单音节清晰度与语言可懂度的关系，估计了在满足一定可懂度条件下的最低信噪比及相应的STI-PA。

| Abstract: | A laboratory test is carried out to test the Mandarin monosyllable clarity and STI-PA with several noises including different bandwidth or different SNR. The relationship between clarity and SNR and between STI-PA and SNR are derived from the test result. The SNR threshold and STI-PA threshold are also estimated based on the relationship between speech clarity and speech intelligibility. |
