Turn-taking and Backchannel Prediction with Acoustic and Large Language Model Fusion

Jinhan Wang, Long Chen, Aparna Khare +6

We propose an approach for continuous prediction of turn-taking and backchanneling locations in spoken dialogue by fusing a neural acoustic model with a large language model (LLM).…

Guided contrastive self-supervised pre-training for automatic speech recognition

Aparna Khare, Minhua Wu, Saurabhchand Bhati +2

Contrastive Predictive Coding (CPC) is a representation learning method that maximizes the mutual information between intermediate latent representations and the output of a given…

Do You Listen with One or Two Microphones? A Unified ASR Model for Single and Multi-Channel Audio

Gokce Keskin, Minhua Wu, Brian King +5

Automatic speech recognition (ASR) models are typically designed to operate on a single input data type, e.g. a single or multi-channel audio streamed from a device. This design de…

Listen with Intent: Improving Speech Recognition with Audio-to-Intent Front-End

Swayambhu Nath Ray, Minhua Wu, Anirudh Raju +7

Comprehending the overall intent of an utterance helps a listener recognize the individual words spoken. Inspired by this fact, we perform a novel study of the impact of explicitly…

Attention-based Neural Beamforming Layers for Multi-channel Speech Recognition

Bhargav Pulugundla, Yang Gao, Brian King +5

Attention-based beamformers have recently been shown to be effective for multi-channel speech recognition. However, they are less capable at capturing local information. In this wo…
