subtitlesfor.me

Basic MVC Web App that convert audio to subtitles by using speech to text from IBM Watson API. Audio can be provided from almost any video and audio formats except aac(due to IBM Watson API limitations), also audio is splitted on several parts to speed up conversion(thanks to ffmpeg).

Audio is converted to SRT caption/subtitle format from Watson STT generated JSON.
