Overview
What you provide
- Provide an accessible audio source and explicitly enable the desired transcription and enrichment options.
What you get
- AssemblyAI returns a transcript with timestamps and the selected additional analysis.
Choosing this tool
AssemblyAI suits a document pipeline where a transcript is only the start and speaker labels or enrichment must be budgeted explicitly. Universal-2 and Universal-3.5 Pro have different language and feature coverage. Deepgram is a live-speech alternative, while GroqCloud provides a simpler Whisper path when enrichment is unnecessary.
A decision worked through
For 100 recorded hours, Universal-2 base transcription is USD 15 and diarization adds USD 2, totaling USD 17 before credits. Universal-3.5 Pro with that same listed add-on is USD 23. Choosing medical mode or extra prompting changes the calculation again.

Setup & workflow
- Choose a model based on the recording language and required features.
- Enable only necessary add-ons on a short sample.
- Compare the reviewed transcript and actual feature charges before scaling.
Requirements & installation
- Create an API key and provide an audio source accessible to the transcription service.
Limits & review
- Add-on availability differs by model, and the maximum trial-hour claim is not a promise for every feature combination. Do not use generated labels as verified identities.
Your part
- Check technical terminology and speaker turns before using the result as a meeting or research record.
