Bone Conducted Signal Guided Speech Enhancement For Voice Assistant on Earbuds

ICASSP 2025accepted

In this work we present a multi-modal, streaming enhancement network to improve speech recognition for voice assistants on earbuds. The proposed model is guided by a bone conducted signal (BCS) to separate the interfering sources from the target speaker signal. We train the model on a simulated spee…

Cleanformer: A Multichannel Array Configuration-Invariant Neural Enhancement Frontend for ASR in Smart Speakers

ICASSP 2023accepted

This work introduces Cleanformer —a streaming multichannel neural enhancement frontend for automatic speech recognition (ASR). This model has a Conformer-based architecture which takes as inputs a single channel each of raw and enhanced signals, and uses self-attention to derive a time-frequency mas…

A Neural Acoustic Echo Canceller Optimized Using An Automatic Speech Recognizer and Large Scale Synthetic Data

ICASSP 2021accepted

We consider the problem of recognizing speech utterances spoken to a device which is generating a known sound waveform; for example, recognizing queries issued to a digital assistant which is generating responses to previous user inputs. Previous work has proposed building acoustic echo cancellation…
