Model Adaptation Using Discriminative Noise Adaptive Training Approach for New Environments

A conventional environment adaptation for robust speech recognition is usually conducted using transform‐based techniques. Here, we present a discriminative adaptation strategy based on a multi‐condition‐trained model, and propose a new method to provide universal application to a new environment using the environment's specific conditions. Experimental results show that a speech recognition system adapted using the proposed method works successfully for other conditions as well as for those of the new environment.
