Abstract

A system for performing end-to-end automatic speech recognition (ASR). The system configured to collect a sequence of acoustic frames associated with a mixture of speeches performed by multiple speakers. Each frame from the sequence of acoustic frames is encoded using a multi-head encoder which encodes each frame into a likelihood of a transcription output and a likelihood of an identity of a speaker. The multi-head encoder thus produces a sequence of likelihoods of transcription outputs and a sequence of likelihoods of identities of the speakers corresponding to the sequence of acoustic frames that are decoded using a decoder performing an alignment operation for producing a sequence of transcription outputs annotated with identities of the speakers, for performing speaker separation.
