A new research paper published on arXiv explores methods for improving automatic speech recognition (ASR) systems' ability to recognize new and rare words. The study compares context biasing techniques, which supply a word list during inference, against speech large language models (LLMs) that use direct context prompting. Results indicate that context biasing methods significantly reduce word error rates for biased words while minimally impacting others, whereas speech LLMs perform well on read speech but show less generalization to non-read speech and are sensitive to prompt variations.
