Combining the Modified CTRANC and Posterior Union Model for Robust Distant Speech Recognition

摘要：

In this paper,we first present a modified crosstalk resistant adaptive noise canceller(CTRANC)algorithm.Then we propose a new approach for robust speech recognition.This new approach consists of two stages：Firstly,the modified CTRANC algorithm is used to suppress noises.which is supplied with noisy speech and produces enhanced speech of which only some portions remain corrupted by noise.Subsequently the second step is to use posterior union model(PUM)to deal with the remaining unknown partial noise corruption.The simulated experiments are given at the end of this paper,showing that the new method is effective.
