SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires edge-tts, ffmpeg, pydub.

What problem does it solve?

This Skill eliminates the manual effort of recording and aligning Chinese voice audio to subtitle timestamps by generating a single time-synchronized WAV track directly from a Chinese SRT file.

Core Features & Use Cases

Chinese SRT → Time-synced TTS WAV: Synthesizes speech for each subtitle entry and places each segment into the correct timeline position.
Duration correction for synchronization: Measures synthesized audio duration and automatically speed-ups (up to 1.3x) or pads with silence to match the subtitle slot.
Edge TTS voice selection: Supports multiple Microsoft Edge TTS Chinese voice options (default: zh-CN-XiaoxiaoNeural), making it easy to match a desired narration style.
Use Case: After translating subtitles to Chinese (ZH SRT), generate the dubbed narration WAV aligned to the translated SRT so it can be used in a YouTube dubbing workflow.
