AudioLine

AudioLine is an audio player that turns your audio into subtitles you can read along with as you listen. Pick a folder of audio, press play, and AudioLine generates subtitles for your recordings. It is great for reviewing lectures, podcasts, interviews, audiobooks, and any spoken-word audio. You can also use it as an audio player with subtitles, adjust the text size, change skip-forward and skip-back intervals, and choose the app appearance.
