We tested some free transcription services with a MP4 video with large amounts of background noise and a very badly recorded voice from a camera microphone.
We tested:
The best result was from amberscript.com which was much much better than the next best result from temi.
Further notes:
- We did not find out how to export the entire subtitle file from veed.io
- temi provides an interface where words that have not been recognized clearly are marked. This helps enormously when manually correcting transcriptions.
- freetranscriptions takes audio files as input, not video files
- amberscript took the longest of all tools to transcribe.
