Abstract
The present disclosure describes techniques for improving speech recognition using a machine learning model. The machine learning model comprises a speech encoder configured to generate acoustic representations based on input speech, an adapter configured to generate adapted representations based on the acoustic representations, and a decoder configured to generate text corresponding to the input speech. A matching loss is applied during training the machine learning model. The matching loss is configured to explicitly force acoustic representations generated by the adapter to align with text embeddings. The machine learning model is fine-tuned by employing parameter-efficient low-rank adaptation. The machine learning model is trained to perform automatic speech recognition with performance improvement and parameter efficiency.
