Voice AI — Kasipan

[ Capabilities / 008 ]

Engineered for
the phone call, not the demo.

→ 001 / TURN-TAKING

Predictive endpointing.

Our endpoint model fires ~120ms before silence, then negotiates barge-in with the user's prosody. Conversations don't stutter.

→ 002 / VOICE

Streaming TTS, custom-cloned.

Bring 90 seconds of audio. We clone, polish, and stream at 22kHz with phoneme-level emotion control. Brand-safe by default.

→ 003 / TELEPHONY

Drop-in to Twilio, Vonage, your PBX.

SIP-native. Works with the numbers you have. Failover routes to a human in < 2s if confidence drops.

→ 004 / TOOLS

Calls your stack, not the other way around.

Native function calling against CRM, scheduler, billing, ticketing. Tools are typed; eval harness rejects builds that hallucinate arguments.

→ 005 / OBSERVABILITY

Every turn, traced.

OpenTelemetry spans for ASR, LLM, TTS and tool calls. Replay any conversation as a flame graph. Diff prompts across deploys.

→ 006 / SAFETY

PII redaction at the edge.

Card numbers, SSNs and PHI scrubbed before transcripts leave your VPC. SOC 2, HIPAA-ready.

→ 007 / EVAL

10k synthetic callers, nightly.

Adversarial test suite runs against every PR. We catch the regression before your customer does.

→ 008 / DEPLOY

Two-week production cutover.

Discovery → prototype → shadow mode → live. We run all four in parallel with your existing line.
