Test on Mandarin Monosyllable Clarity and Speech Intelligibility Estimation With Low SNR

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.
