Investigation of Sampling Techniques for Maximum Entropy Language Modeling Training

ICASSP 2019accepted

Maximum entropy language models (MaxEnt LMs) are log-linear models which are able to incorporate various hand-crafted features and non-linguistic information. Standard MaxEnt LMs are computationally heavy for tasks with a large vocabulary size due to the expensive normalization computation in the de…

Multi-Microphone Neural Speech Separation for Far-Field Multi-Talker Speech Recognition

ICASSP 2018accepted

This paper describes a neural network approach to far-field speech separation using multiple microphones. Our proposed approach is speaker-independent and can learn to implicitly figure out the number of speakers constituting an input speech mixture. This is realized by utilizing the permutation inv…

The Microsoft 2017 Conversational Speech Recognition System

ICASSP 2018accepted

We describe the latest version of Microsoft's conversational speech recognition system for the Switchboard and CallHome domains. The system adds a CNN-BLSTM acoustic model to the set of model architectures we combined previously, and includes character-based and dialog session aware LSTM language mo…
