description: "Synthesize speech from text with Qwen TTS models. TRIGGER when: user wants to convert text to speech, create voiceovers, generate audio narration, read text aloud, build TTS applications, mentions speech synthesis/voice generation/audio output from text, or explicitly invokes this skill by name (e.g. use qwencloud-audio-tts). DO NOT TRIGGER when: user wants speech recognition/ASR, text generation without audio, non-Qwen audio tasks."

# Qwen Audio TTS (Text-to-Speech)

Synthesize natural speech from text using Qwen TTS models.
This skill is part of **qwencloud/qwencloud-ai**.

## Skill directory

Use this skill's internal files to execute and learn. Load reference files on demand when the default path fails or you need details.

| Location | Purpose |
|----------|---------|
| `scripts/tts.py` | Qwen TTS / Qwen Audio TTS (HTTP and WebSocket); current compatibility and defaults are in the model catalog below |
| `scripts/tts_cosyvoice.py` | CosyVoice (WebSocket API) — requires `dashscope` SDK; current compatibility and defaults are in the model catalog below |
| `references/cosyvoice-guide.md` | CosyVoice setup, voices, examples, errors |
| `references/execution-guide.md` | Fallback: curl (standard, instruct, streaming), code generation |
| `references/prompt-guide.md` | Text formatting for speech, instructions templates, voice selection |
| `references/api-guide.md` | API supplement |
| `references/sources.md` | Official documentation URLs |

## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$QWENCLOUD_API_KEY` in shell, `os.environ["QWENCLOUD_API_KEY"]` in Python). The scripts accept `QWENCLOUD_API_KEY`, then `QWEN_API_KEY`, then `DASHSCOPE_API_KEY`. Any check or detection of credentials must be **non-plaintext**: report only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of `.env` or config files that may contain secrets.

**When the API key is not configured, NEVER ask the user to provide it directly.** Instead, help create a `.env` file with a placeholder (`QWENCLOUD_API_KEY=sk-your-key-here`) and instruct the user to replace it with their actual key from the [QwenCloud Console](https://home.qwencloud.com/api-keys). Only write the actual key value if the user explicitly requests it.

## Key Compatibility

Scripts support both **standard QwenCloud API keys** (`sk-...`) and **Token Plan keys** (`sk-sp-...`). Token Plan keys are automatically routed to the Token Plan endpoint for supported TTS models — see [Token Plan Support](#token-plan-support) below.

**Token Plan: do not use curl; always use the bundled Python scripts.**

Coding Plan keys (also `sk-sp-` prefix but purchased via Coding Plan subscription) cannot be used — TTS models are not available on Coding Plan. The script detects key type at startup and routes accordingly. If qwencloud-ops-auth is installed, see its `references/codingplan.md` for full details.

Detect the API key type without exposing the key:

```bash
python3 -c "
import sys; sys.path.insert(0, 'scripts')
from qwencloud_lib import detect_api_key_type
print(detect_api_key_type('scripts/qwencloud_lib.py'))
"
```

| Output | Meaning |
|--------|---------|
| `token-plan` | Token Plan key detected (`sk-sp-` prefix) |
| `payg` | Standard PAYG key detected |
| `not-set` | No API key found in environment |

For Token Plan, fetch and read the current [Token Plan model catalog](https://alioth-intl.alicdn.com/skills-info/models/references/qwencloud-token-plan-models.md), then use an exact listed model with `scripts/tts.py`. If CDN access fails, use the [local fallback](cdn/references/qwencloud-token-plan-models.md).

## Model Selection

> **🚫 CRITICAL — Never override the user's model choice.** If the user (or the request JSON) exp
