Features deep dive

Six pillars, one pipeline. Every layer is replaceable.

We keep the platform honest by making each layer swappable. Drop in your own STT, your own LLM, your own TTS — or take ours and tune it. Below: what each pillar actually gives you.

01 · Multilingual STT

32 languages, code-switching aware, no rerouting.

STT in 32 languages with shared phoneme grids, so a caller can switch from EN to TR mid-sentence without a model handoff. We benchmark WER on your audio before pilot — no marketing numbers.

  • 32 languages, more on request
  • Code-switching mid-sentence
  • Per-language voice + persona
  • Custom WER benchmark on your audio
02 · Low-latency TTS

Sub-second first byte, neural and clone-capable.

TTS designed for real-time conversation. Pick from realistic neural voices, or clone your brand voice with consent flows and watermarking built in. Streaming output keeps the conversation flowing.

  • Sub-second first-byte, p50
  • Streaming chunk output
  • Voice cloning with consent + watermark
  • Per-call voice selection
03 · LLM routing

Right LLM for the right turn.

An LLM router picks the right model per turn — a fast local model for chit-chat, a deeper one for complex flows, a private on-prem model for regulated data. You set the policy; the router enforces it.

  • Per-turn model selection
  • Fallback chain on timeout
  • Private models for regulated data
  • Cost / latency tradeoff per route
04 · Tool calling

Tools an agent can actually call.

Native CRM, calendar, payment, and ticket tools. Add your own with a JSON schema — your agent can call it the same call. Tool traces are first-class in the dashboard, no guessing.

  • Native CRM, calendar, payment
  • Add tools via JSON schema
  • Tool traces in the dashboard
  • Per-tool auth + audit
05 · Recording & QA

Recording, transcripts, and QA — without the legwork.

Lossless recordings with searchable transcripts, sentiment trails, and policy hits. Auto-redact PII before storage, choose retention windows, and export to your data lake.

  • Searchable transcripts + sentiment
  • Auto-redact PII before storage
  • Policy hits surface during the call
  • Export to your data lake
06 · Numbers & SIP

Bring your trunks. Or buy numbers in 70+ countries.

First-class SIP — bring your existing trunks, or buy numbers in 70+ countries through us. Failover, fallback, and warm-transfer to any human-staffed line are built in.

  • BYO SIP trunks
  • Numbers in 70+ countries
  • Failover + fallback
  • Warm-transfer to humans
