**引擎与传输解耦。** 不依赖 Pipecat、不依赖任何传输方式,只依赖四个接口。
|
||||
好处:可以用文件音频端到端测试;接 WebRTC 时只需写薄适配层。
|
||||
|
||||
## Pipecat 实时链路:已闭环
|
||||
|
||||
2026-09-15 复查并修复传输层实验:
|
||||
|
||||
- ✅ 信令、ICE、data channel、双向媒体轨
|
||||
- ✅ `PipelineWorker` 自动 `StartFrame`,自定义 `EngineProcessor` 正常收帧
|
||||
- ✅ 文件音频 → STT → DeepSeek → Qwen3-TTS → WebRTC 非静音回复
|
||||
- ✅ 保留 RTVI 和 `/client/` prebuilt 网页客户端,并提供其需要的 `/start` 入口
|
||||
|
||||
原来的“`process_frame` 调用次数为 0”并非管线接线或模型不兼容。真实根因是
|
||||
Pipecat 启动预热 NLTK `punkt_tab` 时发生运行时下载,20 秒 setup 超时,worker
|
||||
尚未发送 `StartFrame` 就退出。数据预装后帧路由正常,因此确定采用 A 方案:
|
||||
Pipecat 管传输、帧与 RTVI,自有 `ConversationEngine` 管会话语义。
|
||||
|
||||
自写客户端另有两处测试缺陷也已修复:文件结束后的静音帧没有推进 PTS,导致 VAD
|
||||
收不到 700ms 尾静音;接收端又把 WebRTC 自动静音误判为回复。现在成功条件是收到
|
||||
非静音语音,并按实际 WebRTC 采样率保存 WAV。
|
||||
|
||||
2026-09-16 又通过 SSH 隧道用 `/client/` 做了真人浏览器测试:补齐 Playground
|
||||
要求的 `/start` 后,麦克风 → STT → LLM → TTS → 浏览器播放正常,单轮服务端指标
|
||||
约 3.0 秒。这个页面是调试工具而非产品 UI;当前连接期间由 VAD 检出每段话后都会

||||
响应,**尚无唤醒门控**。正式唤醒仍按方案放在 P2 的 N5095 本地端,待机时不上传音频。
|
||||
|
||||
完整记录见代码仓库外的 `P0-Pipecat传输层实验报告.md`(在 Obsidian 笔记库里)。
|
||||
|
||||
### 当前打断边界(2026-09-16)
|
||||
|
||||
当前 `SimpleVAD` 是实验性的 RMS 能量判定:阈值 350、最短语音 300ms、尾静音
|
||||
700ms。它能切分话段和触发下一轮,但不是完整的 barge-in。助手推送音频时检测到
|
||||
用户声音目前只记日志;只有等话段结束,或收到外部 `InterruptionFrame`,才会取消
|
||||
当前异步轮次。浏览器播放器虽有清空能力,服务端尚未把“用户开始说话”可靠地转换为
|
||||
取消生成、清空服务端输出和清空客户端缓冲三个动作。现有测试只证明任务可取消,
|
||||
未证明声学打断端到端闭环。
|
||||
|
||||
### 下一阶段 Agent 方向:Pipecat Flows
|
||||
|
||||
已决定不整体迁移 OpenClaw、Agno、LangGraph 或 LiveKit Agents,而是在现有 Pipecat
|
||||
实时链路上渐进引入 `pipecat-ai-flows`。目标是把 `web_search`、`remember`、
|
||||
`search_memory`、`forget` 等能力变成受策略约束的工具,同时保留现有
|
||||
`MemoryStore`、身份隔离和低延迟语音链路。Flows 与当前自有 `ConversationEngine`
|
||||
的接口并不直接兼容,必须先做独立兼容性实验,再通过 feature flag 灰度迁移;不得
|
||||
直接重写已部署链路。实施交接见笔记库
|
||||
`P1-Pipecat Flows Agent化与记忆改造交接.md`。
|
||||
|
||||
### 实验挖出的 10 个坑
|
||||
|
||||
每个都表现为"什么都没发生",极难排查:
|
||||
|
||||
1. Pipecat 客户端 SDK 不覆盖"Linux x86 盒子接 USB 阵列"这种形态 → 客户端得自己写
|
||||
2. 客户端必须建 data channel 并定期发 `"ping"`,否则服务端一帧音频都不推
|
||||
3. offer 里没有媒体时 aiortc **完全不收集 ICE 候选**(连连通性测试都要加静音轨)
|
||||
4. ICE 收集完成前发 offer → SDP 里 0 个候选地址
|
||||
5. `PipelineWorker.run()` 要 `WorkerParams(task_manager=...)`,不是 `PipelineParams`
|
||||
6. `TaskManager()` 必须在事件循环内创建
|
||||
7. **后台任务里的异常被静默吞掉**,日志里查不到
|
||||
8. 信令回调里必须 `create_task`,不能 `await task.run()`
|
||||
9. Pipecat 会预热 NLTK `punkt_tab`;生产部署必须预装,不能在首个会话临时下载
|
||||
10. `PipelineWorker` 自动发送 `StartFrame`,手工再发会造成重复启动帧
|
||||
|
||||
## Pipecat Flows 兼容性 spike(2026-09-16)
|
||||
|
||||
Phase 1 spike 已完成,7 项验证全通过。代码:`p1/flows_spike.py`(探索)+
|
||||
`app/tests/test_flows_spike.py`(断言版)。完整结论见笔记库的
|
||||
`P1-Flows兼容性Spike结论.md`。
|
||||
|
||||
**最重要的三条**:
|
||||
|
||||
1. **不要装 `pipecat-ai-flows`**。Pipecat 1.10 内置 Flows(`pipecat.flows`),
|
||||
装独立包会报错提示卸载;且独立包 1.4.0 会把 pipecat 降到 1.4.0。
|
||||
2. **用 `PipelineRunner().run(worker)`,不要直接 `worker.run()`**。
|
||||
直接跑时 runner 没挂上,工具执行会失败,异常被转成一句通用的
|
||||
"The function X failed and returned no result.",handler 从不执行。
|
||||
3. **`await flow.initialize(node)`**。它是协程,但签名显示 `-> None` 看不出,
|
||||
漏 await 不报错,只是 role_message/task_messages/工具全部静默失效。
|
||||
|
||||
另有两条:`respond_immediately` 默认 True(initialize 会立刻触发一轮回复,
|
||||
做归因测试时要注意);`role_message` 与 `task_messages` 会**各产生一条
|
||||
system 消息**,两者不要同时用(切回本地 vLLM 时会 400)。

## Pipecat 实时链路状态
|
||||
|
||||
2026-09-15 已闭环:`PipelineWorker` 自动启动,音频帧进入自定义处理器,完整
|
||||
STT → DeepSeek → Qwen3-TTS → WebRTC 返回非静音语音。保留 RTVI 与 `/client/`
|
||||
网页测试入口,并补齐 Playground 启动所需的 `/start`;架构确定采用
|
||||
“Pipecat 管传输,自有引擎管语义”的 A 方案。
|
||||
|
||||
原帧路由问题的根因是 NLTK `punkt_tab` 首次运行下载拖住 Pipecat 预热,导致
|
||||
20 秒 setup timeout;不是框架不支持自定义处理器。服务器已把数据预装到权限 700 的
|
||||
`~/.local/share/ai-companion/nltk_data`,服务启动时会 fail-fast 检查。
|
||||
|
||||
单次文件音频实测:源音频结束到客户端首个非静音约 5.8 秒;其中包含约 0.7 秒
|
||||
VAD 等待,当前仍高于 P1 的 2 秒目标,需要后续单独优化。完整记录见 Obsidian
|
||||
笔记库里的 `P0-Pipecat传输层实验报告.md`。
|
||||
|
||||
2026-09-16 通过 SSH 隧道打开 `http://localhost:7860/client/` 真人实测成功;补齐
|
||||
Playground 使用的 `/start` 后,浏览器麦克风、RTVI、语音回复均正常,单轮服务端
|
||||
指标约 3.0 秒。当前是 P1 调试模式:连接后持续上传并响应每段有效语音,尚未实现
|
||||
P2 的本地唤醒和 20 秒连续对话窗口。
|
||||
|
||||
网页文字输入由 RTVI `send-text` 转为 `LLMMessagesAppendFrame`,适配层会调用
|
||||
`ConversationEngine.respond_to_text()`;回复用标准 LLM 帧返回,因此 Conversation
|
||||
区域可显示用户文字和助手回复,默认也会合成语音。当前 Playground 1.7 还需要
|
||||
完整的 `bot-transcription` / `bot-output` 事件,不能只发送 token 级
|
||||
`bot-llm-text`。
|
||||
|
||||
**姓名记忆已修复并迁移。** 用户明确自报姓名时,同步更新 `users.display_name`
|
||||
和 confirmed 姓名记忆;新连接从用户表恢复称呼,内部 `user_id` 不进入用户可见
|
||||
称呼。姓名疑问句(例如“知道我是谁吗”)不会再被误写为姓名。需要注意:通用的
|
||||
“记住/我喜欢/我习惯”目前仍全部写成 candidate,默认检索不会读取,而且还没有确认
|
||||
和晋升流程;所以通用长期记忆尚未闭环。
|
||||
|
||||
**联网搜索已实现并部署。** DeepSeek 通过 Function Calling 请求 `web_search`,引擎
|
||||
聚合完整的流式工具参数,调用回环地址上的 SearXNG,并把标题、摘要、URL 作为
|
||||
`tool` 消息回灌后生成最终回答。最多连续搜索两轮,搜索失败不会拖垮对话;网页保留
|
||||
一到三个来源 URL,TTS 从“来源:”开始停止朗读。2026-09-16 真实验收中,模型主动
|
||||
搜索、取得 5 条结果并生成带两个来源的回答。
|
||||
|
||||
服务器到 DuckDuckGo、Brave、Wikipedia 会超时,因此 SearXNG 当前只保留并显式
|
||||
启用 Bing、360 搜索、搜狗;其中 360 与搜狗实测有结果,Bing 当前返回空结果。
|
||||
容器只监听 `127.0.0.1:18080`,不向局域网或公网暴露。
|
||||
|
||||
## Agent 与打断的下一阶段
|
||||
|
||||
架构已选择 **Pipecat Flows 渐进改造**,不整体迁移 OpenClaw、Agno、LangGraph 或
|
||||
LiveKit Agents。现有 `ConversationEngine` 已手写最多两轮的搜索工具循环,而
|
||||
Pipecat Flows 依赖 Pipecat `LLMService`、context aggregator 和 PipelineTask;
|
||||
两者不能直接替换。实施必须先完成无传输的兼容性 spike,验证 DeepSeek 流式内容、
|
||||
工具参数聚合、取消传播和 RTVI 文本事件,再用 `AI_AGENT_RUNTIME=legacy|flows`
|
||||
保留回退路径。详细任务与验收见笔记库
|
||||
`P1-Pipecat Flows Agent化与记忆改造交接.md`。
|
||||
|
||||
当前打断不是完整闭环:`SimpleVAD` 在助手推送音频时检测到高能量只记录日志;
|
||||
语音话段要等 700ms 尾静音后才会取消旧轮次。收到 `InterruptionFrame` 时任务确实
|
||||
可以取消,但服务端尚未在用户开口时主动生成该信号,也没有同时清空浏览器已缓冲音频。
|
||||
下一阶段先用合成帧验证“开始说话 → 取消生成 → 清空输出”的控制链;真实 AEC、回声
|
||||
条件下的误触发率仍必须等 N5095 音频硬件到位后验收。
|
||||
|
||||
## 未做的事
|
||||
|
||||
- **没有常驻服务**:TTS 服务和助手都没有 systemd 开机自启(方案 §10 要求 P2 后做)
|
||||
- **没接 Pipecat 管线**:引擎与传输解耦,接 WebRTC 时写薄适配层即可
|
||||
- **网页 HTTPS 尚未启用**:`/client/` 已挂载且 HTTP 返回正常,但浏览器远程取麦克风
|
||||
需要 HTTPS;Tailscale Serve 仍需在 tailnet 管理页启用
|
||||
- **唤醒尚未实现**:当前网页连接后会持续上传麦克风并响应每段有效语音;正式方案
|
||||
是在 N5095 本地做关键词检测,待机时音频不出网
|
||||
- **实时打断尚未闭环**:有能量 VAD、异步任务取消和客户端停播能力,但三者还没有
|
||||
由可靠的 user-started-speaking 事件串起来
|
||||
- **通用长期记忆尚未闭环**:除姓名外的自动抽取均为 candidate,缺少确认、晋升、
|
||||
修改、忘记的用户可见流程
|
||||
- **设备侧代码不存在**:N5095 的外设桥(USB、WebRTC 客户端、串口)尚未开始
|
||||
- **STT 没换**:仍是 2023 年的 Zipformer int8,中文识别率从未测过
|
||||
- **记忆库在服务器上**,而人脸特征按方案必须留在设备端——将来做
|
||||
"删除我的数据"要跨两台机器协调,这个数据边界问题需要单独想
|
||||
- **代码仍在 note_sync 笔记仓库里**,未拆成独立仓库
|
||||
- **代码与设计文档分属两个仓库**:实现位于 `ai-companion`,设计记录位于
|
||||
`note_sync`,状态变更需同步更新两边
