Systems and methods for improved automatic speech recognition systems

Abstract

Selection of training utterances may be carried out in a sample-efficient manner, and the selected training utterances may be annotated to provide improved training information to an ASR system. A computing device may receive, from an ASR system, one or more transcript-score pairs, wherein a transcript-score pair comprises a transcription associated with a voice query and at least one score associated with the transcription. The computing device may determine a likelihood of a word error associated with each transcription of the one or more transcript-score pairs. The computing device may determine, based on the likelihood of the word error, an effect on a word-error rate of the ASR system. The computing device may send at least one of the one or more transcript-score pairs with a threshold effect on the word-error rate of the ASR system to be annotated.
