Claim:
1. A computer implemented method for speech recognition, the method implemented by one or more processors and comprising: receiving, by a deep neural network at a hidden layer, input speech data at a first set of nodes of the hidden layer of the deep neural network and corresponding speaker data at a second set of nodes of the hidden layer of the deep neural network, the second set of nodes serving as an extra input to the deep neural network; and generating, by the deep neural network, a prediction of a phoneme corresponding to the input speech data based on the corresponding speaker data, wherein the generating comprises multiplying the input speech data received at the first set of nodes with a first matrix of weighting coefficients and multiplying the speaker data received at the second set of nodes with a second matrix of weighting coefficients, multiplying the speaker data with the second matrix of weighting coefficients removing speaker variability from the input speech data.
