Chanjing TTS Voice Clone

功能说明

基于用户提供的参考音频公网 URL（由蝉镜服务端拉取）创建音色并合成语音；轮询任务并从接口返回 URL 下载结果。脚本不依赖 ffmpeg/ffprobe。凭据、令牌写回与权限见 manifest.yaml；access_token / expire_in 刷新时会覆盖同文件字段，勿将凭证提交版本库。

运行依赖

python3 与同仓库 scripts/*.py
无 ffmpeg/ffprobe 门控

环境变量与机器可读声明

环境变量键名与说明：manifest.yaml（environment 段）及本文
变量、凭据、permissions.userContent（含参考音公网 URL 由蝉镜拉取）：manifest.yaml

When to Use This Skill

Use this skill when the user needs to generate speech from text, with a user-provided reference voice. The reference audio needs to be provided as a publicly accessible url.

This TTS service supports:

bilingual Chinese and English
adjustment of speech rate
sentence-level timestamp

How to Use This Skill

前置条件（权限验证）：执行本 Skill 前，必须先通过 chanjing-credentials-guard 完成 AK/SK 与 Token 校验。脚本与 guard 使用同一套凭证；无凭证时会执行 open_login_page.py 打开注册/登录页。凭据与审稿对表见 manifest.yaml。

Security & credentials（引用）

Purpose / Credentials / user-supplied reference URL / downloads：见 manifest.yaml 中 credentials 与 clientPermissions（及合规 permissions）；勿与本节以下 API 文档重复维护表格。

Chanjing-TTS-Voice-Clone provides an asynchronous speech synthesis API. Hostname for all APIs is: "https://open-api.chanjing.cc". All requests communicate using json. You should use utf-8 to encode and decode text throughout this task.

Obtain an access_token, which is required for subsequent requests
Call the Create Voice API, which accepts a url to an audio file as reference voice
Poll the Query Voice API until the result is success; keep the voice ID
Call the Create Speech Generation Task API, using the voice ID, record the task_id
Poll the Query Speech Generation Task Status API until the result is success
When the task status is complete, use the corresponding url in API response to download the generated audio file

Get Access Token API

从 ~/.chanjing/credentials.json 读取 app_id 和 secret_key，若无有效 Token 则调用：

POST /open/v1/access_token
Content-Type: application/json

请求体（使用本地配置的 app_id、secret_key）：

{
  "app_id": "<从 credentials.json 读取>",
  "secret_key": "<从 credentials.json 读取>"
}

Response example:

{
  "trace_id": "8ff3fcd57b33566048ef28568c6cee96",
  "code": 0,
  "msg": "success",
  "data": {

Scripts

本 Skill 提供脚本（skills/chanjing-tts-voice-clone/scripts/），与 chanjing-credentials-guard 使用同一配置文件；无 AK/SK 时会执行 open_login_page.py 脚本打开注册/登录页。

| 脚本 | 说明 | |------|------| | create_voice.py | 提交定制声音任务（参考音频 URL），输出 voice_id | | poll_voice.py | 轮询定制声音直到就绪（status=2），输出 voice_id | | create_task.py | 使用定制声音创建 TTS 任务，输出 task_id | | poll_task.py | 轮询 TTS 任务直到完成，输出音频下载 URL |

示例（在项目根或 skill 目录下执行）：

# 1. 创建定制声音（参考音频需为公开 URL）
VOICE_ID=$(python skills/chanjing-tts-voice-clone/scripts/create_voice.py --name "我的声音" --url "https://example.com/ref.mp3")

# 2. 轮询直到声音就绪
python skills/chanjing-tts-voice-clone/scripts/poll_voice.py --voice-id "$VOICE_ID"

# 3. 创建 TTS 任务
TASK_ID=$(python skills/chanjing-tts-voice-clone/scripts/create_task.py --audio-man "$VOICE_ID" --text "Hello, I am your AI assistant.")

# 4. 轮询到完成，得到音频下载链接
python skills/chanjing-tts-voice-clone/scripts/poll_task.py --task-id "$TASK_ID"
