Spext is the easiest way to edit, transcribe and repurpose your audio files. Spext converts uploaded files  to text using APIs like Google, accurately syncs audio + transcribed text and represents silence/ music textually.

So, you can now delete existing words/ sentences, “uh” and “um” fillers or add and remove silence using the text and not waveforms. (You can't add new words/ change existing words yet :))
