Six, Usage Tips and Real-Case Examples

To fully leverage the potential of AI Transcription, we share a few practical tips and real-life scenario examples.

Tips 1: Optimize Audio Quality

The accuracy of transcription is directly related to the quality of the audio. It is recommended to use a noise-reduction microphone during recording and maintain a quiet environment. If the audio has background noise, it can be processed using an audio editing software (such as Audacity) before transcription.

Tips 2: Reasonably Choose Engines

For standard Chinese or English pronunciations, Apple engine should be prioritized for faster speed. For audio with mixed languages, heavy accents, or background noise, the Whisper engine should be chosen for higher recognition rate.

Tips 3: Utilize Time-Line Markers

In the transcription settings, enable “mark time lines by sentences”. This will automatically segment the SRT subtitle file, saving a lot of time for manual alignment.

Real-Case Example 1: Student Classroom Recording to Notes

Little Li is a graduate student who often records lectures. He dragged a 2-hour MP3 recording into AI Transcription, selected “Chinese” and “Whisper engine”. After 10 minutes, the software output了一份带时间戳的TXT document. He used “Command + F” to search for keywords and quickly located important knowledge points, which he then organized into a mind map.

Real-Case Example 2: Self-Made Subtitles for a Video Review

Little Wang, a blogger, recorded a 15-minute video review. He dragged the video file into the software, exported it as SRT format. Then, he imported the subtitle file into Final Cut Pro and made slight adjustments before publishing. The entire process from recording to publishing took only 30 minutes, which was five times faster than manual typing.

Case Study 3: Interview Recording Transcription

Old Zhang, a journalist, needs to transcribe a 45-minute interview recording. He uses the “Dual Engine Mode” of AI Transcription, first generating a draft quickly with the Apple engine, then using the Whisper engine to refine the fuzzy parts. The final output is a CSV file containing speaker markers, which can be directly imported into Excel for analysis.
