name: doubao-tts version: 2.1.0 description: Use Doubao Text-to-Speech (Volcengine TTS) to convert text into audio files. When a user mentions "Doubao TTS," "Doubao Text-to-Speech," "doubao tts," "Volcengine TTS," "volcengine tts," "speech synthesis," "text-to-speech," "TTS," "generate audio," "read text aloud," or any scenario requiring the Doubao/Volcengine Text-to-Speech API, this skill must be triggered.

Doubao TTS Skill (V3)

Use the Volcengine Doubao Text-to-Speech V3 HTTP SSE unidirectional streaming API to convert text into audio files.

Get an API Key (Recommended, New Console)

1. Log in to the Volcengine Console
2. Go to Doubao Voice → Text-to-Speech Large Model → Application Management
3. Create an application or use an existing one
4. On the API Key Management page, get the API Key → corresponding to DOUBAO_TTS_API_KEY

If you have not enabled the service yet, enable it first on the Text-to-Speech Large Model page.

Legacy Console (AppID + Token)

At the bottom of the application details page in the legacy console, you can find:

• APP ID → DOUBAO_TTS_APPID
• Access Token → DOUBAO_TTS_TOKEN

Environment Variables

Variable Name	Description	Recommended
DOUBAO_TTS_API_KEY	API Key (new console, X-Api-Key)	✅
DOUBAO_TTS_APPID	AppID (legacy console, X-Api-App-Id)
DOUBAO_TTS_TOKEN	Access Token (legacy console, X-Api-Access-Key)
DOUBAO_TTS_RESOURCE_ID	Resource ID; leave blank to use the default seed-tts-2.0

Check whether they are configured:

[ -n "$DOUBAO_TTS_API_KEY" ] && echo "API_KEY: set" || echo "API_KEY: not set"
[ -n "$DOUBAO_TTS_APPID" ] && echo "APPID: set" || echo "APPID: not set"
[ -n "$DOUBAO_TTS_TOKEN" ] && echo "TOKEN: set" || echo "TOKEN: not set"

If they are not configured, tell the user to set them (prefer API Key): Set DOUBAO_TTS_API_KEY | Set DOUBAO_TTS_RESOURCE_ID

Legacy console (AppID + Token): Set DOUBAO_TTS_APPID | Set DOUBAO_TTS_TOKEN
