 - **FireRedASR2-LLM**: Designed to achieve state-of-the-art performance and to enable seamless end-to-end speech interaction. It adopts an Encoder-Adapter-LLM framework leveraging large language model (LLM) capabilities.
 - **FireRedASR2-AED**: Designed to balance high performance and computational efficiency and to serve as an effective speech representation module in LLM-based speech models. It utilizes an Attention-based Encoder-Decoder (AED) architecture.

 **Q: What are the input length limitations of ASR models?**
 
 - FireRedASR2-AED supports audio input up to 60s. Input longer than 60s may cause hallucination issues, and input exceeding 200s will trigger positional encoding errors.
-- FireRedASR2-LLM supports audio input up to 30s. The behavior for longer input is untested.
+- FireRedASR2-LLM supports audio input up to 40s. The behavior for longer input is untested. Batch Beam Search: When performing batch beam search with FireRedASR2-LLM, even though attention masks are applied, it is recommended to ensure that the input lengths of the utterances are similar. If there are significant differences in utterance lengths, shorter utterances may experience repetition issues. You can either sort your dataset by length or set `batch_size` to 1 to avoid the repetition issue.
