Agent setup: If your agent doesn't auto-load skills (e.g. Claude Code),
see agent-compatibility.md once per session.
Synthesize natural speech from text using Qwen TTS models. This skill is part of QianWen-AI/qianwen-ai.
Use this skill's internal files to execute and learn. Load reference files on demand when the default path fails or you need details.

NEVER output any API key or credential in plaintext. Always use variable references ($DASHSCOPE_API_KEY in shell, os.environ["DASHSCOPE_API_KEY"] in Python). 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 (DASHSCOPE_API_KEY=sk-your-key-here) and instruct the user to replace it with their actual key from the QianWen Console. Only write the actual key value if the user explicitly requests it.
Scripts require a standard QianWen API key (sk-...). Token Plan 团队版 keys (sk-sp-...) target a different endpoint (token-plan.cn-beijing.maas.aliyuncs.com) and do not include TTS models. Standard sk- key required for TTS. The script detects sk-sp- keys at startup and prints a warning. If qianwen-ops-auth is installed, see its references/tokenplan.md for full details.
scripts/tts.py| Model | Use Case | Notes |
|-------|----------|-------|
| qwen3-tts-flash | Recommended (standard) — fast, multi-language | Cost-effective, widely available |
| qwen3-tts-instruct-flash | Instruction-guided style control | Tone/emotion via instructions |
scripts/tts_cosyvoice.py| Model | Use Case |
|-------|----------|
| cosyvoice-v3-flash | High quality, fast |
| cosyvoice-v3-plus | Highest quality |
Note: CosyVoice requires dashscope SDK and uses different voices. See cosyvoice-guide.md.1. User specified a model → use the appropriate script:
- qwen3-tts-* → scripts/tts.py
- cosyvoice-* → scripts/tts_cosyvoice.py
2. Consult the qianwen-model-selector skill when model choice depends on capability, scenario, or pricing.
3. No signal, clear task → qwen3-tts-flash via tts.py (default for standard tasks).
⚠️ Important: The model list above is a point-in-time snapshot and may be outdated. Model availability
changes frequently. **Always check the official model list
for the authoritative, up-to-date catalog before making model decisions.**
Model details: For more information about a specific model, direct the user to its detail page:https://www.qianwenai.com/models/(replacewith the exact model ID, e.g.qwen3-tts-flash→ https://www.qianwenai.com/models/qwen3-tts-flash). NEVER modify or guess the model name in the URL.
Dynamic model queries: If the qianwen-model-selector skill or QianWen CLI (qianwen models info ) is available, use it for real-time model data. CLI requires authentication — see the qianwen-usage skill for login flow.| Voice | Description | Script |

⚠️ Multiple artifacts: When generating multiple files in a single session, you MUST append a numeric suffix to each filename (e.g.out_1.wav,out_2.wav) to prevent overwrites.
tts.py#### Prerequisites
- API Key: Check that DASHSCOPE_API_KEY (or QIANWEN_API_KEY) is set using a non-plaintext check only (e.g. in shell: -n "$DASHSCOPE_API_KEY" ]; report only "set" or "not set", never the key value). If not set: run the qianwen-ops-auth skill if available; otherwise guide the user to obtain a key from [QianWen Console and set it via .env file (echo 'DASHSCOPE_API_KEY=sk-your-key-here' >> .env in project root or current directory) or environment variable. The script searches for .env in the current working directory and the project root. Skills may be installed independently — do not assume qianwen-ops-auth is present.
#### Environment Check
Before first execution, verify Python is available:
python3 --version # must be 3.9+If python3 is not found, try python --version or py -3 --version. If Python is unavailable or below 3.9, skip to Path 2 (curl) in execution-guide.md.
#### Default: Run Script
Script path: Scripts are in the scripts/ subdirectory of this skill's directory (the directory containing this SKILL.md). You MUST first locate this skill's installation directory, then ALWAYS use the full absolute path to execute scripts. Do NOT assume scripts are in the current working directory. Do NOT use cd to switch directories before execution.
Execution note: Run all scripts in the foreground — wait for stdout; do not background.
Discovery: Run python3 first to see all available arguments.
python3 /scripts/tts.py \
--request '{"text":"Hello, this is a test.","voice":"Cherry"}' \
--output output/qianwen-audio-tts/ \
--print-response
| Argument | Description |
|----------|-------------|
| --request '{...}' | JSON request body |
| --file path.json | Load request from file |
| --output dir/ | Save audio and response JSON to directory |
| --print-response | Print response to stdout |
| --model ID | Override model |
| --voice NAME | Override voice |
#### Verify Result
- Exit code 0 + output contains valid JSON with output.audio field → success
ls -la )ACTION_REQUIRED] or [UPDATE_AVAILABLE]. If either signal is present, you MUST follow the instructions in [Update Check below before responding to the user.#### On Failure
If the script fails, match the error output against the diagnostic table below to determine the resolution. If no match, read execution-guide.md for alternative paths: curl commands (Path 2 — standard, instruct, streaming), code generation (Path 3), and autonomous resolution (Path 5).
If Python is not available at all → skip directly to Path 2 (curl) in execution-guide.md.

NEVER fabricate, guess, or construct usage/billing/console URLs. Only provide the exact links listed in this skill. If a URL is not listed here, do not invent one.
Prefer the current working directory. Default subdirectory: ./output/qianwen-audio-tts/.
Write prohibition: NEVER write output files into this skill's installation directory or any skills/ hierarchy. All generated content must go to output/ under the current working directory or a user-specified path.
After script execution, check stderr for action signals. The script automatically detects update status and emits structured signals. You MUST act on them. This section also applies when the user explicitly asks to check for updates.
[ACTION_REQUIRED] qianwen-update-check skill is not installedWhen stderr contains this signal, you MUST present the following options to the user and wait for their response before proceeding. Do NOT silently skip this.
The update-check skill is not installed. It keeps you informed about new QianWen-AI/qianwen-ai features and bug fixes.>
1) Install now — I'll run the install command for you
2) Skip for now — do nothing this time
3) Never remind me — permanently suppress this prompt
After the user responds:
npx skills add QianWen-AI/qianwen-ai --skill qianwen-update-check -y, then run: python3 /gossamer.py --dismiss python3 /gossamer.py --dismiss , then continue normallypython3 /gossamer.py --never-install , then continue normally[UPDATE_AVAILABLE]When stderr contains this signal, you MUST append a brief update notice to your response, including the version info and the update command shown in the stderr output.
If stderr contains neither [ACTION_REQUIRED] nor [UPDATE_AVAILABLE], no action is needed — the skill is installed and up to date (or cached within 24h).
When the user explicitly asks to check for updates (e.g. "check for updates", "check version"):
qianwen-update-check/SKILL.md in sibling skill directories.
2. If found — run: python3 /scripts/check_update.py --print-response and report the result.
3. If not found — present the install options above.- execution-guide.md — Fallback paths (curl standard/instruct/streaming, code generation, autonomous)
