ReopenAI/Qwen2.5-14B-SeamlessV2

Model Details

本模型是语音-文本->文本的多模态模型。基于seamless-m4t-v2-large的音频编码器和Qwen2.5-14B-Instruct文本模型。

训练：
一阶段使用清洗后的WeNet中文数据（约6000小时）进行ASR任务训练，此阶段除文本模型外全部可训练。
二阶段基于chatgpt-corpus、moss-003-sft-data等数据集的问题，使用Qwen2.5-72B-Instruct-GPTQ-Int4首先继续生成更多轮次的问题，然后使用Qwen2.5-72B-Instruct-GPTQ-Int4生成多轮问题的答案， 问题使用cosyvoice生成对应音频。生成约620k的多轮语音输入->文本回答数据集。进行语音输入->文本回答的问答任务训练。此阶段除文本模型外全部可训练。

优势：训练期间文本模型完全冻结，保留原始能力；seamless-m4t-v2-large编码器平均每秒的音频编码成6-7个token，显著小于whisper的50个token。

Out-of-Scope Use

模型主要使用中文音频训练，英文能力较弱。
