MP3 is the most common compressed audio format: podcasts, recorded interviews, lectures and most voice recorder exports are MP3 files. Upload a .mp3 file and Scriptivox turns the speech in it into timed SRT subtitles, the format YouTube, Vimeo, VLC, Premiere Pro and DaVinci Resolve all accept.
MP3 files come from podcast downloads, voice recorder apps, music software and older recorders. On a phone, save the file to Files or Downloads, then choose it in the upload box.
Leave it on auto-detect or pick one of more than 100 languages. Turn on speaker recognition when more than one person talks.
Read every line in the editor, fix any word, then download the .srt file, ready for YouTube, your video editor or your player.
