一、引言

之前我发表的一篇文章https://blog.csdn.net/pla88888888/article/details/162817260（K100_AI两卡全离线部署音视频说话人角色确认转录系统），采用SoulX-Transcriber多模态大模型实现，在实测中发现超长音视频文件分析时会出现重复输出。这次我尝试用Speaker-Reasoner-4194h多模态大模型来解决该问题，自编程序思路来源于官方代码，代码链接为：https://github.com/ASLP-lab/Speaker-Reasoner/tree/main，如果您觉得该大模型对本工作有用，请引用：

二、方案设计

1. 项目背景与目标

在会议记录、访谈整理等场景中，精确的说话人分离与时间轴对齐是核心需求。本系统旨在利用多模态大模型“Speaker-Reasoner-4194h”的音频理解与推理能力，通过多轮对话机制，实现端到端的智能转录：用户只需上传音频或视频文件，即可自动获得带有说话人ID、性别、精确时间戳的完整转写文本。

2. 系统架构

系统采用B/S架构，前端基于HTML模板提供简洁的上传界面；后端基于Flask框架，负责请求接收、任务调度与结果返回。核心组件包括：

文件预处理模块：使用ffmpeg将任意格式视频/音频统一转码为16kHz单声道WAV，保证模型输入一致性。

推理引擎：通过HTTP接口调用自部署的vLLM服务，承载Speaker-Reasoner-4194h模型。

多轮对话控制模块：实现自适应温度调节、重复输出检测、最大重试与边界校验，确保推理鲁棒性。

转录解析模块：支持秒数、HH:MM:SS、MM:SS.ss等多类时间戳格式，并过滤占位符等无效行，输出结构化片段。

3. 核心工作流程

（1）用户通过Web页面上传文件，后端进行安全校验并保存为临时文件。

（2）ffmpeg转换为16kHz单声道WAV格式，创建临时工作目录用于存放后续音频片段。

（3）发起首轮对话：模型接收完整音频与初始提示，被要求概括整体并给出第一个片段的起止时间边界。

（4）进入循环：每轮解析模型返回的<box>标签获取边界，用ffmpeg精确切出片段音频，构造“当前片段作为O_turn”的新消息，驱动模型逐步推导该片段的说话人、性别与文本。

（5）模型在最终回复中输出<answer>标签，包含所有片段的完整转录。若未正常结束，则从最后一轮提取后备结果。

（6）解析转录文本，转换为带有start、end、speaker、text的标准JSON分段数组，连同原始文本一并返回前端展示。

（7）全程自动清理所有临时文件，保证服务器空间安全。

4. 关键技术细节

鲁棒性设计：单轮最多重试5次，前两次使用极低温度（0.01）和受限采样以抑制随机性，后续逐步放宽；引入重复惩罚系数，并检测连续重复10次以上的模式，一旦发现即触发重试。

边界校验：严格检查<box>中结束时间必须大于起始时间，否则终止对话，防止无效片段。

资源管理：上传限制500MB，所有临时文件使用try-finally确保释放，避免残留。

多格式兼容：解析模块同时支持Speaker [0.0, 3.68]: text和[00:01:23 -> 00:01:45] Speaker1: text等，并通过统一的秒数→时间码转换函数保证输出一致。

5. 部署与展望

系统部署于Flask内置服务器，监听5000端口，可与vLLM服务同机或分布式部署。后续可扩展为异步任务队列，支持更大规模并发处理，并增加说话人声纹注册与自动命名等功能，进一步提升转录体验。

下图展示了整体数据流：

三、实施方法及代码

3.1硬件环境

本方案的硬件平台为一台H3C服务器，配置如下：

需占用两张K100_AI显卡

3.2软件栈

本方案的软件栈基于Docker容器化技术构建，使用经过海光DCU适配的vLLM推理镜像：

镜像（Speaker-Reasoner-4194h）：

harbor.sourcefind.cn:5443/dcu/admin/base/custom:vllm0.15.1-ubuntu22.04-dtk26.04-0130-py3.10-20260220

该镜像基于vLLM0.15.1推理框架、DTK26.04，Python3.10环境，双卡部署Speaker-Reasoner-4194h多模态大模型。

软件项目：
