[Speaker Adaptation][1996] Speaker Adaptation by modeling the speaker variations in a continuous speech recognition system

Explicit speaker variation modelling is important for the acoustic modelling.

This paper tries to model the speaker variations in the hybrid NN/HMM system.

In the acoustic NN model, two speaker space units are used to indicate the speaker variations.

The activations of those two speaker space units are got from a number of speaker units ( actually is the number of speakers in the training set ).

The topology of the speaker sensitive NN is shown below:
