An EM-type of recursiveestimationalgorithm is formulatedin the DFT domainfor joint estimationof time-varyingparameters of distortion channeland additive noise from online degraded speech. Speechfeaturesare estimatedfrom the posteriorestimatesof short-timespeechpowerspectrain anon-the-flyfashion. Experimentswereperformedon speaker-independent continuous speechrecognitionusingfeaturesof perceptuallybasedlinearprediction cepstralcoefficients, log energy, and temporalregression coefficients… CONTINUE READING
