Abstract
Multi-stage fine-tuning for customizing automatic speech recognition with contextual adapters is performed. Entities to customize automatic speech recognition are received and used in an automatic speech recognition pipeline with a fine-tuned version of a speech recognition machine learning model and a fine-tuned version of a contextual adapter. The speech recognition machine learning model and the contextual adapter are fine-tuned in stages that include an initial stage that fine-tunes the speech recognition machine learning model using training data that includes multiple domains and subsequent tuning stages that freeze the speech recognition machine learning model while tuning the contextual adapter and tune the speech recognition machine learning model again.
