Premium voice for Vantage — with Claude as the brain
Claude brain · premium WebRTC voice on Cloudflare · July 18, 2026
Eight cards, ~30 seconds each. What we're proving, how we'll test it, and what it costs. Full proposal downloadable below.
EDGEPOINTE · VANTAGE
What we're proving
Three things at once, in one small test PoC
We move the AI Receptionist and Ask Vantage onto one voice stack that runs on Cloudflare.
Off OpenAI voice — replaced with premium ElevenLabs voices: a Coral-style female matching the Coordinator voice Hidden Creek uses today, plus a warm Ash-style male.
Claude becomes the brain, replacing the smaller Cloudflare model.
More real automation — booking, quoting, lead capture that actually fires reliably.
Tested on our own site — the EdgePointe Vantage tenant. Our property, zero client risk.
One platform. Per-tenant isolation, no in-network egress, flat cost — the model our pricing depends on.
Control
A switch only EdgePointe can flip Staff-only
Provider selection lives in the staff Cockpit — never in the customer console. Owners have no visibility into which brain or voice they run. Every change is written to the audit log.
Brain
Claude (primary) → Cloudflare AI (fallback)
Voice
ElevenLabs (primary) → OpenAI TTS (fallback)
Automatic and manual failover — and a written plan to retire the fallbacks once the new stack proves itself.
Training & guardrails
Your training carries over — and the guardrail gets stronger Non-negotiable
Nothing to redo. Claude reads the exact same owner training notes, persona, and website content you already maintain. The training screen doesn't change.
Closed-book. Both assistants answer only from the website and documents — anything else gets a safe "let me take a message," never a guess.
Enforced by tests — zero fabricated prices, zero unsupported claims.
Bonus: Claude's larger memory lets us feed in far more of the site and real documents than we can today.
Cost
Cheaper than what we're leaving Favorable
Proposed stack
~$0.05–0.06 per minute — about 20 cents on a typical call
Today's OpenAI voice
~$0.15–0.30 per minute
Why
The brain is a small slice of a call; premium voice is the main cost — and we control it
Better brain, better voice, lower cost. Estimates the PoC will confirm with real per-call numbers.
How we test it
Scripted calls, measured head-to-head
One tenant, behind a flag that's off by default. Scripted calls in the browser — no phone number needed, so it proceeds ahead of the EIN.
Book a tour · ask hours · ask price (quote the rate card only) · capture a lead · one Spanish turn · take a message · interrupt mid-sentence.
Measured against the current stack on latency, tool accuracy, voice quality, and real cost.
Go / no-go: under 800ms voice-to-voice · 95%+ tool accuracy · zero fabricated prices · cost at or below today.
Status
Approved — and underway
The proposal and build plan are approved; scaffolding has begun.
Needed to start
ElevenLabs key + the two chosen voice IDs, sign-off on the Ash-style male, and two Cloudflare dashboard clicks
Timeline
Roughly one to two weeks to a go/no-go readout
Risk
Flag off by default — production is untouched throughout
