Video Audio Replace
Replace a video's original audio with TTS-generated voice while maintaining precise timing alignment. Also supports generating subtitles from video using Whisper.
Step 1: Generate subtitles from video (optional)
If you don't have an SRT file, generate one from the video using the included script: # Generate subtitles from video (uses faster-whisper, free, local) generate_subtitles.py video.mp4 -o subtitles.srt -l zh Or manually with Python: # Using faster-whisper (recommended, local, free) pip install faster-whisper srt python3 << 'EOF' from faster_whisper import WhisperModel import srt from datetime import timedelta model = WhisperModel("base", device="cpu", compute_type="int8") segments, info = model.transcribe("input_video.mp4", language="zh") # Generate SRT def format_time(seconds): td = timedelta(seconds=seconds) return f"{td.seconds//3600:02d}:{(td.seconds%3600)//60:02d}:{td.seconds%60:02d},{td.microseconds//1000:03d}" srt_content = "" for i, seg in enumerate(segments, 1): start = format_time(seg.start) end = format_time(seg.end) srt_content += f"{i}\n{start} --> {end}\n{seg.text.strip()}\n\n" with open("subtitles.srt", "w", encoding="utf-8") as f: f.write(srt_content) EOF
Step 2: Replace audio with TTS
Use the generated SRT to create a new video with TTS voice.
When to use
Dubbing videos with AI-generated voice Converting subtitle files to voice-over Creating multilingual video versions
API Keys (choose one)
ElevenLabs: Set ELEVENLABS_API_KEY environment variable Edge TTS (free, no key needed): Use --engine edge
System dependencies
ffmpeg sox (optional, for advanced processing)
Basic usage (ElevenLabs)
video-audio-replace --video input.mp4 --srt subtitles.srt --output output.mp4 --voice "Liam"
Using Edge TTS (free, no API key)
video-audio-replace --video input.mp4 --srt subtitles.srt --output output.mp4 --engine edge --voice "zh-CN-YunxiNeural"
Options

English voice (ElevenLabs)
video-audio-replace --video 2028.mp4 --srt 2028.srt --output 2028_final.mp4 --voice "Liam"
Chinese voice (Edge TTS)
video-audio-replace --video video.mp4 --srt subs.srt --output result.mp4 --engine edge --voice "zh-CN-YunxiNeural"
How it works
Extract original audio from video Split audio into segments based on subtitle timestamps Generate TTS audio for each subtitle segment Adjust TTS speed (within 0.85-1.15x) to match original segment duration Add silence padding to fill any remaining time gap Merge all segments preserving original timing gaps Replace video audio with aligned TTS audio
