This paper compares three techniques for recognizing continu­ ous speech in the presence of additive car noise: 1) transforming the noisy acoustic features using a mapping algorithm, 2) adapta­ tion of the Hidden Markov Models (HMMs), and 3) combination of mapping and adaptation. We show that at low signal-to-noise ratio (SNR) levels, compensating in the feature and model domains yields similar performance. We also show that adapting the HMMs with the mapped features produces the best perfor… CONTINUE READING
