Loving this TurboScribe.AI tool after paying for the unlimited subscription ($120/year). I can do mass transcription of subtitles in many languages (Chinese, Indonesian, English, etc.) with all the audio files I have. I need to get more of Stephen Tong and other lecturers' audio files. It's tempting to get Tim Keller's $800 USB sermons.
On the technical note: The original mp3 files I feed TurboScribe do not sync up with the subtitle srt files it generated for. However, it allows for downloading the mp3 files which it apparently corrected for text sync up after upload, so that's the fix. So I have to not just download the srt files, but also the audio files to replace the original mp3 files.
