Key features
Deepgram Aura
- Aura-1 and Aura-2 voices
- Aura-2 is described as the efficient model for high-volume deployment; Aura-1 is the lower-cost tier.
- Flux TTS for live conversations
- A newer model that carries tone across turns, reports what was heard when a caller interrupts, and starts audio in as little as 80 ms.
- Per-character billing
- Pay as you go is $0.015 per 1,000 characters on Aura-1, $0.030 on Aura-2 and $0.045 on Flux TTS.
- Pairs with speech-to-text and voice agents
- The same account covers speech-to-text, a managed Voice Agent API and audio intelligence, billed from one balance.
- Flexible deployment
- Runs in the cloud, in a private cloud or on-premises; self-hosted containers need NVIDIA GPUs and an Enterprise plan.
- Compliance statements
- Deepgram says it is SOC 2 Type 1 and 2 certified, signs a BAA for Enterprise customers, and offers an EU endpoint.
Rime

- Positioned as the lowest-latency model, with 78 voices in English, French, German and Spanish and a listed 37 ms median time to first audio.
- Coda v2 text to speech
- Positioned as the most natural model, with 313 voices across 10 languages including Japanese, Arabic and Hindi, and custom pronunciation lexicons.
- Prism speech to speech
- A model that hears the call, reasons over it and speaks; text is generated before audio so guardrails can check it, and it supports tool calls mid-call.
- Real-time streaming and telephony
- WebSocket streaming and 8 kHz phone audio are on every plan, with LiveKit, Pipecat and other agent-platform integrations.
- Custom voices and self-hosting

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
