Case Study: Super achieves 30% STT cost savings with AssemblyAI

Super cuts STT costs by 30% with AssemblyAI

Super, a vertical Voice AI platform for real estate, was facing challenges scaling its high-volume phone agents due to limitations with its previous speech-to-text providers. Issues included awkward turn detection that hurt conversation flow, restrictive concurrency limits, and ineffective keyterm prompting for critical real estate vocabulary like property names and addresses.

By switching to AssemblyAI's Universal-3 Pro Streaming model, Super achieved a fast integration and significantly improved its voice agents. AssemblyAI provided smarter turn detection for more natural conversations and the concurrency needed to scale. The results included an approximately 30% cost savings on real-time transcription and a refocused engineering team that could concentrate on product development instead of maintaining the transcription layer.
