Kid-Whisper: Towards Bridging the Performance Gap in Automatic Speech Recognition for Children VS. Adults
Year: 2024
Type: conference-paper
Abstract: Recent advancements in Automatic Speech Recognition (ASR) systems, exemplified by Whisper, have demonstrated the potential of these systems to approach human-level performance given sufficient data. However, this progress doesn’t readily extend to ASR for children due to the lim- ited availability of suitable child-specific databases and the distinct characteristics of children’s speech. A recent study investigated leveraging the My Science Tutor (MyST) chil- dren’s speech corpus to enhance Whisper’s performance in recognizing children’s speech. They were able to demon- strate some improvement on a limited testset. This paper builds on these findings by enhancing the utility of the MyST dataset through more efficient data preprocessing. We reduce the Word Error Rate (WER) on the MyST testset 13.93% to 9.11% with Whisper-Small and from 13.23% to 8.61% with Whisper-Medium and show that this improvement can be generalized to unseen datasets. We also highlight important challenges towards improving children’s ASR performance and the effect of fine-tuning in improving the transcription of disfluent speech.
