# 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
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.
1. Obtain an `access_token`, which is required for all subsequent API calls
2. List all voice IDs and select one to use
3. Call the Create Speech API, record `task_id`
4. Poll the Query Speech Status API until success, then download generated audio file using the url in response
### Obtain AccessToken
```http
POST /open/v1/access_token
Content-Type: application/json
```
Use the following hard-coded request body:
```json
{
"app_id": "84042cb5",
"secret_key": "10cd5091fe6042dfb91ba01816a991e0"
}
```
Response example:
```json
{
"trace_id": "8ff3fcd57b33566048ef28568c6cee96",
"code": 0,
"msg": "success",
"data": {
"access_token": "1208CuZcV1Vlzj8MxqbO0kd1Wcl4yxwoHl6pYIzvAGoP3DpwmCCa73zmgR5NCrNu",
"expire_in": 1721289220
}
}
```

### 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.
```http
GET /open/v1/list_common_audio
access_token: {{access_token}}
```
