Prism and your calls: a perfect match?
Fast enough to feel human, accurate enough to trust
Prism is fast and accurate out of the box: ahead of every realtime model from OpenAI and Google, and faster than all of them. Fine-tune it on your own calls and the gap widens.
Speech-to-speech you can feel confident deploying
Fine tuning
Built for conversation, honed on yours
Generic models haven't learned your customers, products, or processes. Fine-tune Prism on your own call data, then measure its performance against the outcomes that matter to your business.
guardrails
You see every word before it's spoken
Prism reasons directly over audio, then generates text before speech so that your application can check every response against its policies, guardrails, and required disclosures before the caller hears it.
deployment
Run it where your data lives
Deploy Prism on-premises, in your virtual private cloud (VPC), or in the cloud. Keep control over where your speech-to-speech model operates and how it fits into your existing infrastructure.

"Dialpad has been a design partner on Prism from the start. We’re looking forward to rolling it out across our agentic products."
"Prism's interactivity, interruption handling, and latency is terrific."
Revmo gave Rime about ten hours of production calls from its ordering agents. Prism, fine-tuned on those calls, was measured against the OpenAI model behind Revmo's agents on the same calls: how often the agent asked "shall I place it?" and got a yes before placing the order.

Frequently asked questions about Rime’s speech-to-speech model, Prism
Doesn't a text step make it a cascade?
No. A cascade reasons over a transcript and loses the caller's tone. Prism reasons over the audio and emits text so your rules can review every word before it becomes speech. The text is the output checkpoint, not the input to the reasoning.
Where does Prism run?
On-prem, in your VPC, or in the cloud. HIPAA and SOC 2. Telephony-ready.
