本文档对语音合成SDK支持的能力进行说明。
|
||||
|
||||
* **SDK名称**：语音合成SDK
|
||||
* **SDK开发者**：北京火山引擎科技有限公司
|
||||
* **主要功能**：语音合成SDK支持将文字实时合成语音，适用于实时语音播报的场景，如有声阅读、导航、语音助手等等。

|
||||
# 合成能力
|
||||
**在线合成**：云端合成，发起网络请求，边合成边播放（支持TTS的websocket接口，能够使用声音复刻音色以及TTS大小模型音色）
|
||||
**离线合成**：本地离线引擎合成，需要相关资源文件，边合成边播放；
|
||||
<span id="合成策略"></span>
|
||||
# 合成策略
|
||||
离在线语音合成SDK，除了可以单独使用的在线合成及离线合成外，提供了在线合成发生网络超时后，切换离线合成的两种策略，用户可以通过配置建连超时和接收超时两个参数来控制切换的敏感程度。
|
||||
|
||||
* **在线优先**：优先发起在线合成，失败后（网络超时），启动离线合成引擎开始合成；
|
||||
* **并发合成**：同时发起在线合成与离线合成，在线请求失败的情况下，使用离线合成数据，该模式下，可以配置更短的超时时间以提升效果，但会消耗更多系统性能；
|
||||
|
||||
<span id="合成场景"></span>
|
||||
# 合成场景
|
||||
语音合成SDK提供了两种种合成场景，以满足不同的需求：
|
||||
|
||||
* **普通场景**：又称单句场景，引擎每次启动，只合成、播放一句音频的模式。
|
||||
* **小说场景**：适用于听书业务，每次启动引擎后可以根据需求合成多句音频。
|
||||
|
||||
<span id="合成效果"></span>
|
||||
# 合成效果
|
||||
通过对发音人、音调、音量和语速等参数的调整，可以获得不同的发声效果，更好满足您业务场景中的播报需求。

# 模型与API
|
||||
支持的模型：[文本生成能力](/docs/82379/1330310#b318deb2)
|
||||
支持的API ：
|
||||
|
||||
* [Responses API](https://www.volcengine.com/docs/82379/1569618)：新推出的 API，简洁上下文管理，增强工具调用能力，缓存能力降低成本，新业务及用户推荐。
|
||||
* [Chat API](https://www.volcengine.com/docs/82379/1494384)：使用广泛的 API，存量业务迁移成本低。
|
||||
|
||||
<span id="1d866118"></span>
|
||||
# 使用示例
|
||||
<span id="f6222fec"></span>
|
||||
## 多轮对话
|
||||
实现多轮对话，需将包含系统消息、模型消息和用户消息的对话历史组合成一个列表，以便模型理解上下文，并延续之前的话题进行问答。

|
||||
| |* **实时过程反馈**：多轮交互场景，实时了解任务当前的处理阶段。|\
|
||||
| |* **更高的容错性**：中途出错，也能获取到已生成内容，避免非流式输出失败无返回的情况。|\
|
||||
| |* **简化超时管理**：保持客户端与服务端的连接状态，避免复杂任务耗时过长而连接超时。 |
|
||||
|
||||
通过配置 **stream** 为 `true`，来启用流式输出。
|
||||
```JSON
|
||||
...
|
||||
"model": "doubao-seed-1-6-251015",
|
||||

|
||||
|
||||
<span id="3821b26a"></span>
|
||||
## 设置最大回答
|
||||
当控制成本或者回答问题时间，可通过限制模型回答长度实现。当回答篇幅较长，如翻译长文本，避免中途截断，可通过设置`max_tokens`更大值实现。
|
||||
```JSON
|
||||
...
|
||||
"model": "doubao-seed-1-6-251015",
|
||||
"messages": [
|
||||
{"role": "user","content": "What are some common cruciferous plants?"}
|
||||
],
|
||||
"max_tokens": 300
|
||||
...
|
||||
```
|
||||
|
||||
> 完整示例代码，请参见 [控制回答长度](/docs/82379/2123288#c7fbdbe3)。
|
||||
|
||||
<span id="8783d86f"></span>
|
||||
## 异步输出
|
||||
当任务较为复杂或者多个任务并发等场景下，可使用 Asyncio 接口实现并发调用，提高程序的效率，优化体验。

## 深度思考
|
||||
模型在输出回答前，先对输入问题进行系统性分析与逻辑拆解，再基于拆解结果生成回答。
|
||||
可以显著提升回复质量，但会增加 token 消耗，详细信息请参见[深度思考](/docs/82379/1449737)。

|
||||
## 工具调用
|
||||
通过集成内置工具或连接远程 MCP 服务器，您可以扩展模型的功能，以便更好回答问题或执行任务。当前支持：
|
||||
|
||||
* 内置工具：搜索网络、检索数据、图片处理等。
|
||||
* 调用自定义函数。
|
||||
* 访问三方MCP服务。
|
||||
|
||||
详细信息请参见[工具概述](/docs/82379/1827538)。

# 使用说明
|
||||
|
||||
* 模型关键限制：
|
||||
* 最大上下文长度（Context Window）：即单次请求模型能处理的内容长度，包括用户输入和模型输出，单位 token 。超出最大上下文长度的内容时，会截断并停止输出。如碰到上下文限制导致的内容截断，可选择支持更大上下文长度规格的模型。
|
||||
* 最大输出长度（Max Tokens）：即单次模型输出的内容的最大长度。如碰到这种情况，可参考[续写模式 Prefill Response](/docs/82379/1359497)，通过多次续写回复，拼接出完整内容。
|
||||
* 每分钟处理内容量（TPM）：即账号下同模型（不区分版本）每分钟能处理的内容量限制，单位 token。如默认 TPM 限制无法满足您的业务，可通过[工单](https://console.volcengine.com/workorder/create?step=2&SubProductID=P00001166)联系售后提升配额。举例：某模型的 TPM 为 500w，一个主账号下创建的该模型的所有版本接入点共享此配额。
|
||||
* 每分钟处理请求数（RPM）：即账号下同模型（不区分版本）每分钟能处理的请求数上限，与上面 TPM 类似。如默认 RPM 限制无法满足您的业务，可通过[工单](https://console.volcengine.com/workorder/create?step=2&SubProductID=P00001166)联系售后提升配额。
|
||||
* 各模型详细的规格信息，请参见 [模型列表](/docs/82379/1330310)。
|
||||
* 用量查询：
|
||||
* 对于某次请求 token 用量：可在返回的 **usage** 结构体中查看。
|
||||
* 输入/输出内容的 token 用量：可使用 [Tokenization API](https://www.volcengine.com/docs/82379/1528728) 或 [Token 计算器](https://console.volcengine.com/ark/region:ark+cn-beijing/tokenCalculator)来估算。
|
||||
* 账号/项目/接入点维度 token 用量：可在 [用量统计](https://console.volcengine.com/ark/region:ark+cn-beijing/usageTracking) 页面查看。

# 接口说明
|
||||
精品长文本语音合成为异步合成服务，提供“创建合成任务”和“查询合成结果”两个接口，也可通过http回调获取合成结果。
|
||||
请确认是否可满足业务需求再进行接入，本产品适用于需要批量合成较长文本，且对返回时效性无强需求的场景，单次可支持10万字符以内文本，异步返回音频。对于输入的文本请求，会进入集群排队处理，返回时长会受集群负载影响波动，通常返回时间会在数十分钟，最长返回时延3小时以内。如出现长时间未返回情况，如无报错，请耐心等待。
|
||||
长文本合成分为“普通版”和“情感预测版”，两者需要开通不同的服务，接口地址不同，支持的音色列表也不相同，请仔细阅读文档。
|
||||
:::warning
|
||||
创建合成任务的频率限制为10 QPS，请勿一次性提交过多任务。
|
||||
本产品不适合对于时效性有强需求的场景，如有需求建议接入语音合成（短文本）接口。
|
||||

|
||||
<span id="鉴权"></span>
|
||||
# 鉴权
|
||||
请求接口时，需要携带`Resource-Id`和`Authorization`两个header，缺一不可。

# Flutter Web 本地调试启动指南
|
||||
|
||||
> 本文档供 AI 编码助手阅读，用于在本项目中正确启动 Flutter Web 调试环境。
|
||||
|
||||
## 项目结构
|
||||
|
||||
- Flutter 应用目录：`airhub_app/`
|
||||
- 后端服务入口：`server.py`（根目录，FastAPI + Uvicorn，端口 3000）
|
||||
- 前端端口：`8080`
|
||||
|
||||
## 环境要求
|
||||
|
||||
- Flutter SDK（3.x）
|
||||
- Python 3.x（后端服务）
|
||||
- PowerShell（Windows 环境）
|
||||
|
||||
## 操作系统
|
||||
|
||||
Windows（所有命令均为 PowerShell 语法）
|
||||
|
||||
---
|
||||
|
||||
## 启动流程（严格按顺序执行）
|
||||
|
||||
### 1. 杀掉旧进程并确认端口空闲
|
||||
|
||||
```powershell
|
||||
# 杀掉占用 8080 和 3000 的旧进程
|
||||
Get-NetTCPConnection -LocalPort 8080 -ErrorAction SilentlyContinue | ForEach-Object { taskkill /F /PID $_.OwningProcess 2>$null }
|
||||
Get-NetTCPConnection -LocalPort 3000 -ErrorAction SilentlyContinue | ForEach-Object { taskkill /F /PID $_.OwningProcess 2>$null }
|
||||
|
||||
# 等待端口释放
|
||||
Start-Sleep -Seconds 3
|
||||
|
||||
# 确认端口已空闲（无输出 = 空闲）
|
||||
Get-NetTCPConnection -LocalPort 8080 -ErrorAction SilentlyContinue
|
||||
Get-NetTCPConnection -LocalPort 3000 -ErrorAction SilentlyContinue
|
||||
```
|
||||
|
||||
### 2. 启动后端服务器（音乐生成功能依赖此服务）
|
||||
|
||||
```powershell
|
||||
# 工作目录：项目根目录
|
||||
cd d:\Airhub
|
||||
python server.py
|
||||
```
|
||||
|
||||
成功标志：
|
||||
```
|
||||
INFO: Uvicorn running on http://0.0.0.0:3000 (Press CTRL+C to quit)
|
||||
[Server] Music Server running on http://localhost:3000
|
||||
```
|
||||
|
||||
### 3. 设置国内镜像源 + 启动 Flutter Web Server
|
||||
|
||||
```powershell
|
||||
# 工作目录：airhub_app 子目录
|
||||
cd d:\Airhub\airhub_app
|
||||
|
||||
# 设置镜像源（必须，否则网络超时）
|
||||
$env:PUB_HOSTED_URL = "https://pub.flutter-io.cn"
|
||||
$env:FLUTTER_STORAGE_BASE_URL = "https://storage.flutter-io.cn"
|
||||
|
||||
# 启动 web-server 模式
|
||||
flutter run -d web-server --web-port=8080 --no-pub
|
||||
```
|
||||
|
||||
成功标志：
|
||||
```
|
||||
lib\main.dart is being served at http://localhost:8080
|
||||
```
|
||||
|
||||
### 4. 访问应用
|
||||
|
||||
浏览器打开：`http://localhost:8080`
|
||||
|
||||
---
|
||||
|
||||
## 关键规则
|
||||
|
||||
### 必须使用 `web-server` 模式
|
||||
- **禁止**使用 `flutter run -d chrome`（会弹出系统 Chrome 窗口，不可控）
|
||||
- **必须**使用 `flutter run -d web-server`（只启动 HTTP 服务，手动用浏览器访问）
|
||||
|
||||
### `--no-pub` 的使用条件
|
||||
- 仅修改 Dart 代码（无新依赖、无新 asset）→ 加 `--no-pub`，编译更快
|
||||
- 新增了 `pubspec.yaml` 依赖或 `assets/` 资源文件 → **不能**加 `--no-pub`
|
||||
|
||||
### 端口管理
|
||||
- 固定使用 8080（Flutter）和 3000（后端），不要换端口绕过占用
|
||||
- 每次启动前必须先确认端口空闲
|
||||
- 停止服务后等 3 秒再重新启动
|
||||
|
||||
### 热重载
|
||||
- 在 Flutter 终端按 `r` = 热重载（保留页面状态）
|
||||
- 按 `R` = 热重启（重置页面状态）
|
||||
- 浏览器 `Ctrl+Shift+R` = 强制刷新
|
||||
|
||||
---
|
||||
|
||||
## 停止服务
|
||||
|
||||
```powershell
|
||||
# 方法1：在 Flutter 终端按 q 退出
|
||||
|
||||
# 方法2：强制杀进程
|
||||
Get-NetTCPConnection -LocalPort 8080 | ForEach-Object { taskkill /F /PID $_.OwningProcess }
|
||||
Get-NetTCPConnection -LocalPort 3000 | ForEach-Object { taskkill /F /PID $_.OwningProcess }
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 常见问题排查
|
||||
|
||||
| 问题 | 原因 | 解决方案 |
|
||||
|------|------|---------|
|
||||
| 端口被占用 | 旧进程未退出 | 执行第1步杀进程，等3秒 |
|
||||
| 编译报错找不到包 | 使用了 `--no-pub` 但有新依赖 | 去掉 `--no-pub` 重新编译 |
|
||||
| 网络超时 | 未设置镜像源 | 设置 `PUB_HOSTED_URL` 和 `FLUTTER_STORAGE_BASE_URL` |
|
||||
| 页面白屏 | 缓存问题 | 浏览器 `Ctrl+Shift+R` 强刷 |
|
||||
| 音乐功能不工作 | 后端未启动 | 先启动 `python server.py` |
|
||||
|
||||
---
|
||||
|
||||
## 编译耗时参考
|
||||
|
||||
- 首次完整编译（含 pub get）：90-120 秒
|
||||
- 增量编译（`--no-pub`）：60-90 秒
|
||||
- 热重载（按 r）：3-5 秒
|
||||
- 热重启（按 R）：10-20 秒

### 重要规则：
|

- 如果用户输入太模糊（如"嗯"、"不知道"），请发挥想象力，赋予咔咔此刻最可能在做的事。
|
||||
- 歌词长度控制在 4-8 行即可，不要太长。
|
||||
- 歌词必须包含完整结构：至少 [verse 1] + [chorus] + [verse 2] + [chorus] + [outro]，总共 16-24 行。这样才能生成完整的歌曲（60秒以上）。歌词太短会导致音乐只有20-30秒，绝对不可以！
|
||||
- 不要输出任何解释性文字，只输出 JSON。

|

#### 选中态交互修复
|
||||
- 生成完成后自动清除 `_selectedMoodIndex`，不再残留选中状态
|
||||
|
||||
### 第八次对话完成的工作（2026-02-09）
|
||||
|
||||
#### 音乐生成 API 全链路接入（第七次对话中完成，此处补记）
|
||||
- **SSE 实时进度**：点击心情卡片 → 发 POST 到后端 → SSE 流式推送 lyrics/music/saving/done/error 各阶段
|
||||
- **MusicGenerationService 单例**：生成任务在后台运行，页面切走不中断
|
||||
- **切回页面恢复**：切回音乐页弹窗通知生成结果，不在其他页面自动播放
|
||||
- **进度环动画**：环形光晕进度条（匹配 HTML 版视觉）+ 翻面歌词时仍可见
|
||||
- **进度条防闪烁**：用 `_crawlId` 取消令牌确保同一时间只有一条爬升动画
|
||||
- **超时友好提示**：气泡显示"网络开小差了，再试一次~"
|
||||
- **歌词清洗**：前后端双重清理（去 `\n`、去 `[verse]` 等结构标签、去 JSON 引号）
|
||||
- **歌名修复**：后端优先取 LLM 返回的 `song_title`，歌词增长至 16-24 行
|
||||
- **对话气泡样式**：文字垂直居中 + 三角尾巴
|
||||
- **通知页展开 bug 修复**：`AnimatedCrossFade` → `ClipRect + AnimatedSize` 避免文字竖排
|
||||
|
||||
#### 启动时加载历史歌曲
|
||||
- **后端**：`/api/playlist` 接口扫描 `Capybara music/` 目录，返回所有 mp3 + 歌词
|
||||
- **Service 层**：`MusicGenerationService.fetchPlaylist()` 拉取列表
|
||||
- **前端**：`initState` 异步调用，将服务器歌曲插入唱片架最前面（去重，不重复加载硬编码的 4 首）
|
||||
- **当前服务器上有 19 首 AI 生成歌曲 + 4 首原始歌曲，重编译后唱片架不再丢失**
|
||||
|
||||
#### 故事生成接入豆包 API
|
||||
- **后端**：`server.py` 新增 `/api/create_story` 接口，SSE 流式调用豆包 Chat API
|
||||
- **模型**：Doubao-Seed-1.6-lite（`doubao-seed-1-6-lite-250515`），关闭深度思考加快响应
|
||||
- **Prompt**：`prompts/story_director.md`，儿童故事创作大师，400-600 字，JSON 输出
|
||||
- **前端串联**：
|
||||
- `StoryGeneratorModal` 返回选中素材 Map（角色/场景/道具分类）
|
||||
- `DeviceControlPage` 把素材传给 `StoryLoadingPage`
|
||||
- `StoryLoadingPage` 调真实 API，SSE 实时进度（连接→生成→解析→完成）
|
||||
- `StoryDetailPage` 无需改动，已支持接收动态故事数据
|
||||
- **故事保存**：生成的故事文本保存到 `Capybara stories/` 目录
|
||||
- **错误处理**：超时提示、API 异常、空内容兜底，错误时显示"返回重试"按钮
|
||||
|
||||
#### 唱片架高度优化
|
||||
- 限制唱片架弹窗高度为 3.5 行，超出部分滚动查看
|
||||
- 半行露出作为"还有更多"的视觉提示
|
||||
|
||||
#### Windows 编码问题全面修复
|
||||
- `sys.stdout` / `sys.stderr` 强制 UTF-8（Windows 默认 GBK 导致中文乱码）
|
||||
- Doubao API 请求体手动 `json.dumps + encode("utf-8")`，避免 `requests` 用 GBK 编码
|
||||
- SSE 流使用 `ensure_ascii=True`，确保前端 `jsonDecode` 100% 正常
|
||||
- `resp.encoding = "utf-8"` 强制豆包返回流按 UTF-8 解码
|
||||
- 已清理 4 个编码出错时保存的乱码故事文件
|
||||
|
||||
#### 书架加载历史故事
|
||||
- **后端**：`/api/stories` 接口扫描 `Capybara stories/` 返回所有故事标题+内容
|
||||
- **前端**：`initState` 异步拉取，历史故事排在预设故事之后
|
||||
- **保存联动**：新生成的故事保存后，真实标题+内容即时加入书架（不再用 mock 数据）
|
||||
- **封面区分**：预设故事显示封面图，AI 生成的故事显示淡紫渐变"暂无封面"占位
|
||||
- **乱码过滤**：API 层自动跳过无中文标题的异常文件
|
||||
|
||||
### 正在做的
|
||||
- 下一步待定
|
||||
- TTS 语音合成待后续接入（用户去开通火山语音服务后再做）
|
||||
- 故事封面方案待定（付费生成 or 免费生成）
