Time-frequency distributions for automatic speech recognition.

Time-frequency distributions for automatic speech recognition.

The use of general time-frequency distributions as features for automatic speech recognition (ASR) is discussed in the context of hidden Markov classifiers. Short-time averages of quadratic operators, e.g., energy spectrum, generalized first spectral moments, and short-time averages of the instantan...
