# 实时对话功能实现(第一阶段 MVP)
|
||||
|
||||
## 项目概述
|
||||
|
||||
实现第一阶段(MVP):**本地语音录制 + 浏览器语音识别转写**。点击"实时对话"按钮 → 输入行内展开波形录制条 → 停止后自动转写为文字 → 文字填入输入框或直接发送。
|
||||
|
||||
第一阶段**不接入语音大模型、不依赖后端与 API Key**,转写由浏览器内置 Web Speech API 完成,零配置可用。
|
||||
|
||||
---
|
||||
|
||||
## 交互流程
|
||||
|
||||
1. 点击"实时对话"按钮(`VoiceRecordingButton`)
|
||||
2. 输入行内展开 `VoiceRecordingInline` 录制条(不弹窗),自动开始录音
|
||||
3. 显示波形动画(AnalyserNode 实时音量)+ 时长
|
||||
4. 点击停止 → 停止录音并触发浏览器语音识别
|
||||
5. 识别成功 → 短暂显示"转写完成" → 回调文本,由调用方填入输入框或直接发送
|
||||
6. 识别失败(无语音 / 权限拒绝 / 网络异常)→ 录制条内提示并支持重试
|
||||
|
||||
---
|
||||
|
||||
## 技术架构
|
||||
|
||||
```
|
||||
用户点击"实时对话"按钮
|
||||
│
|
||||
▼
|
||||
VoiceRecordingButton(输入行内展开录制条,不弹窗)
|
||||
│
|
||||
▼
|
||||
VoiceRecordingInline 内联波形录制条
|
||||
├── useVoiceRecording:MediaRecorder 录制 + AnalyserNode 实时波形
|
||||
├── AudioWaveform:SVG 波形动画 + 时长显示
|
||||
└── useSpeechRecognition:Web Speech API 实时转写
|
||||
│
|
||||
▼
|
||||
点击停止 → speech.stop() 返回文本 → onTranscribed(文本) → 填入输入框
|
||||
```
|
||||
|
||||
## 前端实现
|
||||
|
||||
### 组件
|
||||
|
||||
| 文件 | 说明 |
|
||||
|------|------|
|
||||
| `components/conversation/voice-recording-button.tsx` | 语音输入按钮:点击后输入行内展开录制条(局部状态,不弹窗) |
|
||||
| `components/conversation/voice-recording-inline.tsx` | 内联波形录制条:波形 + 时长 + 停止/取消,停止后自动转写 |
|
||||
| `components/conversation/audio-waveform.tsx` | SVG 波形可视化组件 |
|
||||
| `components/conversation/index.ts` | 组件统一导出 |
|
||||
|
||||
### Hook
|
||||
|
||||
| 文件 | 说明 |
|
||||
|------|------|
|
||||
| `hooks/use-voice-recording.ts` | 语音录制逻辑(MediaRecorder + AnalyserNode,波形/时长/停止/取消) |
|
||||
| `hooks/use-speech-recognition.ts` | 浏览器语音识别(Web Speech API,start/stop/cancel,返回文本与错误) |
|
||||
|
||||
## 接入位置
|
||||
|
||||
- 创建页主输入行:`web/src/pages/create/index.tsx`(`CreationComposer` 的 `creation-chat-controls`)
|
||||
- 画布助手面板:`canvas-assistant-panel.tsx`、`canvas-local-agent-panel.tsx`(输入行 left 插槽)
|
||||
- 测试页:`web/src/pages/test-voice-recording.tsx`(路由 `/test-voice-recording`)
|
||||
|
||||
## 使用示例
|
||||
|
||||
```tsx
|
||||
import { VoiceRecordingButton } from "@/components/conversation/voice-recording-button";
|
||||
|
||||
<VoiceRecordingButton
|
||||
disabled={isBusy}
|
||||
onTranscribed={(text) => setPrompt((prev) => (prev.trim() ? `${prev} ${text}` : text))}
|
||||
/>
|
||||
```
|
||||
|
||||
## 浏览器支持
|
||||
|
||||
- 语音识别使用 Web Speech API(`SpeechRecognition` / `webkitSpeechRecognition`),Chrome / Edge 支持
|
||||
- 不支持时录制条内提示"当前浏览器不支持语音识别,请使用 Chrome 或 Edge 浏览器",并可取消
|
||||
- 识别语言默认 `zh-CN`,可通过 `useSpeechRecognition({ lang })` 调整
|
||||
|
||||
## 已删除内容
|
||||
|
||||
以下第二阶段实验代码已全部删除:
|
||||
|
||||
### 前端
|
||||
|
||||
- `components/conversation/realtime-conversation.tsx`、`realtime-conversation-button.tsx`、`voice-recording-overlay.tsx`
|
||||
- `hooks/use-websocket.ts`、`stores/conversation-mode-store.ts`
|
||||
- `services/api/stt.ts`(后端 Whisper 转写客户端)
|
||||
|
||||
### 后端
|
||||
|
||||
- `service/stt.go`(OpenAI Whisper 转写)、`model/stt.go`(`stt_results` 表)
|
||||
- `handler/routes.go` 中 `RegisterSTTRoutes`、`main.go` 中路由注册
|
||||
- `database/schema.go` 中 `STTResult` 模型注册、`repository/repository.go` 中 `CreateSTTResult`
|
||||
|
||||
## 验证情况
|
||||
|
||||
- 后端 `go build ./...`:通过
|
||||
- 前端 `npx tsc --noEmit`:无本次新增类型错误(上游遗留 style profile / image.ts 错误除外)
|
||||
- 浏览器手动测试(真实麦克风 + 语音识别)未运行,需在 Chrome/Edge 下验证
|
||||
|
||||
## 下一步
|
||||
|
||||
- [x] 内联波形录制 + 浏览器语音识别自动转写(第一阶段 MVP)
|
||||
- [x] 移除第二阶段实验代码(WebSocket / WebRTC / Realtime API)
|
||||
- [ ] 语音播放功能(TTS)
|
||||
- [ ] 语音消息发送和显示
|
||||
- [ ] 真正实时对话(WebSocket + WebRTC + Realtime API,后续阶段)

# 实时对话功能组件(第一阶段 MVP)
|
||||
本目录实现第一阶段(MVP):**本地语音录制 + 浏览器语音识别转写**。点击"实时对话"按钮 → 输入行内展开波形录制条 → 停止后自动转写为文字 → 文字填入输入框或直接发送。
|
||||
|
||||
## 零配置说明
|
||||
|
||||
第一阶段**不接入语音大模型、不依赖后端与 API Key**:录音完成后直接使用浏览器内置 Web Speech API(`SpeechRecognition`)识别,转写全程在前端完成。
|
||||
|
||||
- 支持的浏览器:Chrome / Edge(Chromium 内核)
|
||||
- 不支持时录制条内会明确提示,并可取消
|
||||
- 识别语言默认 `zh-CN`,见 `useSpeechRecognition` 的 `lang` 参数
|
||||
|
||||
---
|
||||
|
||||
## 组件列表
|
||||
|
||||
### 1. `VoiceRecordingButton` - 语音输入按钮
|
||||
|
||||
点击后输入行内展开波形录制条(不弹窗),自动开始录音;停止后自动转写并回调文本。使用局部状态,多个输入行可独立使用。
|
||||
|
||||
**使用示例:**
|
||||
```tsx
|
||||
import { VoiceRecordingButton } from "@/components/conversation/voice-recording-button";
|
||||
|
||||
<VoiceRecordingButton
|
||||
disabled={isBusy}
|
||||
onTranscribed={(text) => setPrompt((prev) => (prev.trim() ? `${prev} ${text}` : text))}
|
||||
/>
|
||||
```
|
||||
|
||||
### 2. `VoiceRecordingInline` - 内联波形录制条
|
||||
|
||||
输入行内展示的录制控件:波形动画 + 时长 + 停止/取消按钮;停止后自动转写,失败可重试。`VoiceRecordingButton` 默认使用本组件。
|
||||
|
||||
**使用示例:**
|
||||
```tsx
|
||||
import { VoiceRecordingInline } from "@/components/conversation/voice-recording-inline";
|
||||
|
||||
<VoiceRecordingInline
|
||||
onTranscribed={(text) => setPrompt((prev) => (prev.trim() ? `${prev} ${text}` : text))}
|
||||
onCancel={() => setOpen(false)}
|
||||
/>
|
||||
```
|
||||
|
||||
### 3. `AudioWaveform` - 音频波形可视化
|
||||
|
||||
SVG 波形可视化组件,支持实时数据更新。
|
||||
|
||||
---
|
||||
|
||||
## Hook
|
||||
|
||||
### `useVoiceRecording` - 语音录制 Hook
|
||||
|
||||
封装 MediaRecorder API 和 AnalyserNode,提供录制状态、波形数据、控制方法(供波形动画与时长展示)。
|
||||
|
||||
### `useSpeechRecognition` - 浏览器语音识别 Hook
|
||||
|
||||
封装 Web Speech API(`SpeechRecognition`/`webkitSpeechRecognition`),提供 `start()` / `stop(): Promise<string>` / `cancel()`,返回是否支持、识别错误。转写不依赖后端。
|
||||
|
||||
---
|
||||
|
||||
## 完整集成示例
|
||||
|
||||
```tsx
|
||||
import { useState } from "react";
|
||||
import { VoiceRecordingButton } from "@/components/conversation/voice-recording-button";
|
||||
|
||||
function ChatInput() {
|
||||
const [prompt, setPrompt] = useState("");
|
||||
|
||||
const handleTranscribed = (text: string) => {
|
||||
// 转写结果填入输入框,用户确认后发送
|
||||
setPrompt((current) => (current.trim() ? `${current} ${text}` : text));
|
||||
};
|
||||
|
||||
return (
|
||||
<div className="flex items-center gap-2">
|
||||
<textarea value={prompt} onChange={(e) => setPrompt(e.target.value)} placeholder="输入消息..." />
|
||||
{/* 点击后输入行内展开波形录制条,停止后自动转写 */}
|
||||
<VoiceRecordingButton onTranscribed={handleTranscribed} />
|
||||
<button>发送</button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## 接入位置
|
||||
|
||||
- 创建页主输入行:`web/src/pages/create/index.tsx`(`CreationComposer` 的 `creation-chat-controls`)
|
||||
- 画布助手面板:`canvas-assistant-panel.tsx`、`canvas-local-agent-panel.tsx`(输入行 left 插槽)
|
||||
- 测试页:`web/src/pages/test-voice-recording.tsx`
|
||||
|
||||
## 下一步
|
||||
- [x] 内联波形录制(不弹窗),停止后自动转写
|
||||
- [x] 移除第二阶段实验代码(WebSocket / Realtime API / 旧浮层组件)
|
||||
- [x] 移除后端 STT 接口与数据库表(第一阶段不接入语音大模型)
|
||||
- [ ] 语音播放功能(TTS)
|
||||
- [ ] 语音消息发送和显示
|
||||
- [ ] 多模态对话(图片、视频)
|
||||
- [ ] 真正实时对话(WebSocket + WebRTC + Realtime API,后续阶段)
