Pricing or terms sourceCode, model and service licensing
API access is not a license to model weights or open-source deployment. You need recording/data permissions; biometric features have an addendum. Terms permit service and training uses of customer data, with plan-dependent opt-out, and separate de-identified-data rights. Do not assume no training or zero retention; confirm your processing agreement and settings.
Basis and limits of the recorded score
The existing 4.5 editorial score is retained; its original worksheet is not recorded. This docs-only review does not re-score the product or establish performance or superiority.
Overview
AssemblyAI documents separate APIs for pre-recorded, realtime and short synchronous transcription. Speech Understanding analyzes transcripts for summaries, sentiment and topics. Model choice determines language support and available options; speaker diarization may add charges rather than being included in the base rate.
Consider it for developers building transcription or call-review pipelines with their own user interface and error review. Compare recorded versus live billing and budget add-ons separately. A transcript or inferred sentiment is a model result that needs checking, not an exact record or a person's verified emotional state.
