What problem does it solve? It turns written text into playable audio files without manual recording, using Volcengine's Doubao speech synthesis service with configurable voices, emotions, and speech rates. ## Core Features & Use Cases - Text-to-Speech Synthesis: Calls the Doubao TTS V3 HTTP SSE unidirectional streaming API to generate MP3, PCM, or OGG Opus audio files. - Voice and Emotion Control: Supports multiple Chinese and English voices across seed-tts-1.0 and seed-tts-2.0 models, plus emotion and speech-rate tuning. - Dual Authentication: Works with either the new console API Key or legacy AppID plus Access Token credentials. - Use Case: A user asks to read an article aloud; the skill runs the bundled tts.py script and returns a playable MP3 link in the workspace. ## Quick Start Ask the assistant to convert a piece of text into an audio file with Doubao TTS, optionally naming a voice or emotion, after setting the DOUBAO_TTS_API_KEY environment variable.
