How Do and Work?

Let’s first understand how these AI transcription services function before diving into the comparisons:

Otter utilizes sophisticated natural language processing (NLP) and speech recognition algorithms to generate transcripts from audio or video files. You can record meetings, interviews, lectures, and more or upload pre recorded audio/video.

Otter’s AI then gets to work transcribing the media, inserting proper punctuation, formatting speakers, filtering out background noises, and even generating keywords. The technology has advanced enough to recognize different voices and insert speaker names. takes a somewhat different approach. Instead of purely relying on AI, they combine machine learning algorithms with a global network of experienced human editors and fact checkers.

So after the AI attempts to transcribe your files, human experts refine, edit, and fact check the transcripts to boost accuracy significantly. This allows Fireflies to achieve over 99% precision for various speech types. The editing also enriches transcripts by fixing errors, inserting proper names/terms, adding punctuation, and formatting text.
