Speech enhancement using auditory-based spectral amplitude estimators
Published 2013“…The original speech signal is subjected to three types of noises, namely, white noise, pink noise and cockpit noise. The proposed estimator is applied to the noisy speech signal to obtain the enhanced speech signal and the objective measures of speech quality such as the segmental SNR (SNRseg) and the log-likelihood-ratio (LLR) are obtained. …”
