# PESQ,STOI

Data description：

Voicebank-DEMAND is a synthetic dataset created by mixing up clean speech and noise.The clean speech is extracted from the Voice Bank corpus, and the noise is from the Diverse Environments Multichannel Acoustic Noise Database (DEMAND). The training set contains 28 speakers with 4 signal-to-noise ratios (SNRs) (15, 10, 5, and 0 dB) and the test set contains 2 speakers with 4 SNRs (17.5, 12.5, 7.5,and 2.5 dB). The training set contains 11,572 utterances (9.4h) and the test set contains 824 utterances (0.6h). The lengths of utterances range from 1.1s to 15.1s with an average of 2.9s.
