AssemblyAI vs ElevenLabs Scribe

For high-volume call center transcription, the three heaviest attributes all favor AssemblyAI. On batch price, AssemblyAI charges $0.0035 per audio minute versus ElevenLabs Scribe at $0.003667, a meaningful difference at scale. Speaker diarizationdiarization - Splitting a transcript by speaker, so you can see who said what. is a paid add-on for AssemblyAI at about $0.02 per hour, but it is included in ElevenLabs Scribe's base price, which partially offsets the batch rate gap. AssemblyAI supports 200+ concurrent async jobs versus ElevenLabs Scribe's 8 concurrent STT requests on base plans, a critical advantage for high call volumes. AssemblyAI also includes sentiment analysis natively, which ElevenLabs Scribe does not list as available, directly supporting QA and analytics workflows. The concurrency gap alone would create serious bottlenecks at scale for ElevenLabs Scribe.

On batch pricing, ElevenLabs Scribe charges about $0.003667 per audio minute versus AssemblyAI at $0.0035 per audio minute, making AssemblyAI slightly cheaper. Both tools offer Python and JavaScript/Node SDKs and WebSocket streaming APIs, so those attributes are level. Both provide word-level timestampsword-level timestamps - The API reports exactly when each word is spoken in the audio, for subtitles and highlighting.. On supported audio formats, AssemblyAI covers 30+ formats compared to Scribe's 9 listed formats, giving AssemblyAI an edge there. However, ElevenLabs Scribe posts a meaningfully better third-party WER of 2.18% versus AssemblyAI's 3.02%, which matters for transcription quality in production products. The batch price gap is small at about 5%, SDKs and streaming are tied, and Scribe's accuracy advantage tilts the overall developer value proposition narrowly in its favor.

The available facts cover API-level attributes such as batch pricing, WERWER - Word error rate - the share of words a transcription gets wrong; lower is more accurate., concurrency, diarization, and compliance. None of them address the five attributes that decide the dictation use case: supported platforms, local versus cloud audio processing, AI formatting and editing features, one-time versus subscription app pricing, or app integrations with host applications. Without facts on any of these attributes, neither AssemblyAI nor ElevenLabs Scribe can be distinguished for personal voice-typing on a computer.

For clinical transcription under US healthcare privacy law, the HIPAA BAAHIPAA BAA - A signed Business Associate Agreement that lets you handle protected health information under US healthcare privacy law. is the absolute gate. AssemblyAI includes a HIPAA BAA as a standard offering, while ElevenLabs Scribe restricts it to enterprise-only plans, immediately disqualifying Scribe for most clinical operators outside enterprise tiers. On the next two equally weighted attributes, both tools offer PII redaction as a paid add-on and both support custom vocabulary, so those are even. SOC 2 Type II is verified for both. On the final differentiator, AssemblyAI offers a self-host and on-prem option, which ElevenLabs Scribe does not publish any equivalent for, further strengthening AssemblyAI's position for security-sensitive healthcare deployments. The HIPAA BAA gap alone is decisive here.

For self-hostedself-host - Run the software on your own servers instead of the vendor’s cloud. deployment, the single most critical factor is whether a vendor actually offers a self-host or on-prem option. AssemblyAI explicitly supports self-hosting, while no such fact exists for ElevenLabs Scribe. This alone is decisive given the 5 out of 5 weight on this criterion. The remaining attributes, including model weights license, hardware requirements, maintenance status, and model parameters, have no published facts for either tool, so they cannot favor ElevenLabs Scribe. AssemblyAI wins on the heaviest criterion and is not disadvantaged on any other measurable attribute in this use case.

On the two heaviest attributes, both tools tie: streaming latency is vendor-claimed at 150 ms each, and both offer WebSocket streaming APIs. The tiebreaker falls on streaming price, where ElevenLabs Scribe charges about $0.39/hr versus AssemblyAI at about $0.45/hr, giving Scribe a meaningful cost edge for high-volume voice agent deployments. On concurrencyconcurrency - How many phone calls the platform can handle at the same time., AssemblyAI supports 100 new streams per minute versus Scribe's 8 concurrent STT requests on free and PAYG plans, which favors AssemblyAI. Both offer custom vocabulary. Scribe's streaming price advantage of $0.0065 versus $0.0075 per audio minute outweighs AssemblyAI's concurrency lead for most voice-agent workloads, where per-minute cost accumulates continuously.
