Abstract
This report discusses the principles and preliminary experimental results obtained with an algorithm based on Expectation-Maximization (EM) to approach the problem of noise reduction over the telephone line. Recognition experiments have been carried out using speaker-independent (SI) recognition systems based on Hidden Markov Models (HMMs). Preliminary conclusions are outlinedFile in questo prodotto:
