Premium voice example
When the voice is the brand, upgrade the TTS. Swapping in ElevenLabs Flash v2.5 ($0.10/min) — while keeping the same STT and LLM — brings a typical call to around $0.14–0.15/min.
You decide per agent: cost-efficient models for high-volume operational calls, premium voices for customer-facing brand moments.
You choose the models

Speech-to-text (STT)
How the agent hears and transcribes the caller.
Text-to-speech (TTS)
The voice your customers hear — from cost-efficient to studio-grade.
Language model (LLM)
The reasoning that runs the conversation and decides the next action.

Pricing questions
How is the per-minute price calculated?
Every call is billed by the models you choose: one STT rate, one LLM rate and one TTS rate, added together per minute. The entry-level stack (Soniox + Gemini 2.5 Flash + Smallest Lightning v3.1) works out to about $0.06/min. Swap in premium models and the per-minute rate goes up accordingly — you always see the total before you launch.
What counts as an add-on?
Advanced noise cancellation ($0.004/min) and post-call transcription ($0.007/min) are optional and only cost when you enable them. LLM prompt overage ($0.004/min) applies only when a call's prompt exceeds 5,000 tokens — the first 5,000 are included.
Why would I pick a premium voice?
For customer-facing brand calls where the voice matters, you can upgrade TTS — for example to ElevenLabs Flash v2.5 at $0.10/min — bringing a typical call to around $0.14–0.15/min. For high-volume operational calls, the entry-level stack keeps costs low.
Are there seat or user fees?
No. There are no per-seat or per-agent licenses. You pay for the minutes you use, and dashboards, transcripts, follow-ups and integrations are part of the platform.
Do you offer volume or enterprise pricing?
Yes. As your volume grows we work with you on tailored pricing and dedicated support. Talk to sales for a quote built around your projected minutes.
