Chanjing TTS

When to Use This Skill

Use this skill when the user needs to generate audio from text.

Chanjing TTS supports:

both Chinese and English
multiple system voices
adjustment of speech speed
sentence-level timestamp in result

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。本 Skill 与 guard 使用同一套凭证（~/.chanjing/credentials.json）；脚本在无凭证时会执行 open_login_page 脚本，在默认浏览器打开 AK/SK 注册/登录页，并提示配置命令。

Multiple APIs need to be invoked. All share the domain: "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 all subsequent API calls
List all voice IDs and select one to use
Call the Create Speech API, record task_id
Poll the Query Speech Status API until success, then download generated audio file using the url in response

Obtain AccessToken

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": {
    "access_token": "1208CuZcV1Vlzj8MxqbO0kd1Wcl4yxwoHl6pYIzvAGoP3DpwmCCa73zmgR5NCrNu",

  }
}

Select a Voice ID

Obtain all available voice IDs via API, and select one that fits the task at hand. The dialect/accent can be deduced from the voice name.

Scripts

本 Skill 提供脚本（skills/chanjing-tts/scripts/），带权限验证：与 chanjing-credentials-guard 使用同一配置文件；无 AK/SK 时会执行 guard 的 open_login_page 脚本，在浏览器打开注册/登录页，并提示配置命令。

脚本	说明
`list_voices`	列出公共声音人，默认输出 id/name 表，可选 `--json` 输出完整数据
`create_task`	创建 TTS 任务，输出 task_id
`poll_task`	轮询任务直到完成，输出音频下载 URL（full.url）

示例（在项目根或 skill 目录下执行）：

# 1. 列出可用声音，选取一个 id
python skills/chanjing-tts/scripts/list_voices

# 2. 创建合成任务
TASK_ID=$(python skills/chanjing-tts/scripts/create_task \
  --audio-man "f9248f3b1b42447fb9282829321cfcf2" \
  --text "Hello, I am your AI assistant.")

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