Live Subtitle & Translator provides real-time speech-to-text captioning and instant translation directly in your browser. Whether you're watching videos, attending web conferences, or listening to audio on any website, this extension captures the audio and displays live subtitles in a floating, draggable overlay.

Key Features:
- Real-time Captioning — Captures tab audio and generates subtitles word-by-word using AI-powered speech recognition (STT), with smooth typing animation for natural readability.
- Live Translation — Translates recognized speech in real-time using streaming AI translation APIs, displaying results token-by-token alongside the original text.
- Separate STT & Translation Providers — Mix and match any combination of speech recognition and translation services. Use one provider for STT and a different one for translation.
- Multi-Provider Support — Works with OpenAI Whisper, Alibaba Cloud Paraformer, Zhipu GLM-ASR, Volcengine ASR, Tencent Cloud ASR, DeepSeek, Google Gemini, Qwen, Moonshot, Baichuan, MiniMax, SiliconFlow, and custom OpenAI-compatible endpoints.
- Smart Audio Capture — Automatically detects page media elements (video/audio) for zero-dialog capture. Falls back to microphone or screen sharing when needed.
- Pause-Aware Line Breaks — Detects natural speech pauses and starts a new subtitle line automatically, keeping the flow synchronized with the speaker.
- Customizable Appearance — Set font color and background color for both original and translated text independently. Supports transparent backgrounds with automatic text shadows for readability.
- Draggable Subtitle Overlay — Move the subtitle box anywhere on the page by dragging the handle.
- Bilingual UI — Switch between Chinese and English interface.
