Voice Personalization

A voice that actually sounds like you.

001

Most voice AI sounds like a robot reading a script. Yours shouldn't. Pick from over 100 voices, each with its own accent, tone, and personality. Preview any voice instantly. Adjust the speed — 0.6x for calm and deliberate, 1.5x for brisk and energetic. Dial the creativity slider so the assistant stays professional when needed and conversational when it counts. The result isn't a voice bot. It's your brand, on a call.

Test every call before it matters.

You'd never deploy software without testing it. Voice should be the same. The built-in test panel lets you make real calls to your assistant — your browser becomes the phone. You speak, it responds, you see the full transcript scroll by live. Audio meters show you're being heard. Latency readouts confirm speed. Tool calls appear inline so you know exactly when the assistant retrieved data or triggered an action.

06 / Vendor freedom

No vendor lock-in.

Use your preferred providers for speech, reasoning, and voice generation. Swap any piece of the pipeline without touching the rest.

07 / Conversation helpers

Filler phrases.

Give your assistant something to say while it thinks — a quick “let me look that up” — so callers stay engaged instead of hanging up.

08 / High availability

Failover built in.

If one text-to-speech provider goes down, the system switches to backup nodes automatically. Your calls keep running, callers never notice.

The voice workflow

From setup to phone call.

Step 01

Choose a voice

Search the voice library, hear a preview, and pick the one that fits your brand. Accents, styles, languages — all browsable in one place.

Step 02

Tune the experience

Set how fast the assistant talks. Decide how quickly it responds after someone finishes speaking. Write a short filler phrase for those brief moments when it's thinking.

Step 03

Test and publish

Make a test call right from your browser. Hear the voice. Read the transcript. Check the timing. When it feels right, hit publish — and your assistant is live.

Your callers deserve better than hold music.

Give them a voice assistant that answers instantly, sounds human, and actually helps. Setup your telephony route in under ten minutes.
