Custom Voice Selection and Tuning

Your voice agent sounds right for your business, at a comfortable pace, saying your names and terms correctly.

A voice that sounds wrong for your business, speaks too fast or mispronounces your own name makes callers trust the call less. This add-on chooses and tunes the voice of the voice agent you already run. You hear a shortlist read with your own sample lines, pick one, and we tune pace and pronunciation until it sounds right.

  • Picks a voice from a shortlist read with your lines
  • Sets a comfortable speaking pace for your callers
  • Pronounces your names and terms correctly

What it is

Custom Voice Selection and Tuning is an add-on that chooses and tunes the voice, pace and pronunciations of an existing Upmark Labs voice agent. You hear a shortlist of voices, pick one, and we adjust speed and pronunciation until it sounds right. It fits voice agents only, not text agents.

Why businesses buy it

On the phone, the voice is your brand. Callers form an impression in the first few seconds, and a mispronounced product name or a rushed delivery makes the whole call feel careless. Tuning fixes those details before callers hear them. The written scope covers a shortlist, your choice of voice, pace adjustments and a pronunciation list for your names and terms, all checked on test calls, so the voice agent sounds right from its first live call.

Problems this solves

The voice agent sounds robotic and callers hang up early

This add-on lets you hear a shortlist of voices and pick the one that suits your business. The chosen voice is then tuned with the parent voice agent and tested on real call flows.

The agent mispronounces your business, product or street names

Pronunciations are adjusted for the words that matter to you. We keep tuning until names and terms sound right to your ear, then record the settings in the documentation.

Callers struggle to follow because the agent talks too fast

Speaking pace is adjusted as part of the tuning. The agent can sound calm and clear on the phone, rather than rushing callers through important details.

A good fit if

Callers have said the agent sounds robotic, rushed or wrong for your brand.
The agent mispronounces your business name, street names, product names or staff names.
Your callers skew older, younger or regional, and the voice should suit them.
Your voice agent is an Upmark Labs build, or you are ordering one with this.

Not the right fit if

Your agent works in text, not on the phone. Custom Persona and Brand Voice Tuning tunes written tone instead.
You need the agent to speak a second language. Additional Language Pack adds one.
Your text agent has no phone line yet. Voice Channel Add-on adds one first.
You want what the agent says rewritten, not how it sounds. Small script changes fit in monthly maintenance.

How it works

  1. Your preferences are gathered. We ask about your callers, your brand and any voices you like or dislike.
  2. A shortlist is prepared. You hear the same sample lines read by several voices available on your voice platform.
  3. You pick the voice. Your choice becomes the agent's voice for every call.
  4. Pace and pronunciation are tuned. Speaking speed, pauses and the spelling-out of tricky names and terms are adjusted.
  5. Test calls confirm it. We run test calls with the parent agent, you listen, and one revision round follows before handover.

What you provide within 72 hours

Your portal lists these the moment you order. Delivery starts the working day after everything is in and your access is checked.

  • The order reference of the voice agent
  • A list of names, places and terms the agent must say correctly, with how they sound
  • Who your callers are, and any voice style you want or want to avoid
  • Access to your voice platform account, shared securely as agreed at intake
  • One person who chooses the final voice
The 72-hour rule. Send everything on your checklist, including access, within 72 hours of ordering so your build starts on time.

Expected benefits and how to measure them

  • Helps callers feel comfortable staying on the line
  • Can reduce confusion caused by mispronounced names
  • Makes the agent sound more like your business
Early hang-ups
Compare calls ending in the first moments of the greeting, from call logs, for four weeks before and after.
Repeat requests
Sample call transcripts monthly and count times callers asked the agent to repeat itself.
Caller feedback
Note comments about the voice from callers or staff before and after tuning.

Before you start: Save a few recordings of current calls and note your early hang-up count from the call logs.

These are things to track, not promised results. Outcomes depend on your data, your team and your market.

Running costs

Per-minute costs stay with your voice platform, billed to your account. Some premium voices cost more per minute than standard ones; we show you any difference before you choose.

Custom requirements

Cloning a specific person's voice, or tuning several voices for different lines, is beyond this add-on. Describe it in the checkout note for a written Change Quote. Larger or bespoke projects go through the Custom AI request form instead.

Keep it running

New product or staff names will need adding to the pronunciation list over time. That is a quick change under the parent product's maintenance, which grows in line with the add-on's price.

Adds $75/mo to maintenance

Covered by the main product's maintenance, which grows by this amount.

Questions about this product

How many voices do I get to choose from?

A shortlist picked to fit your callers and brand, drawn from the voices available on your voice platform. Each one reads the same sample lines from your own script, so you compare like with like. If none feels right, we prepare a second shortlist within the same build.

Can the agent say my business name properly?

Yes. Pronunciation of names is the most common reason for this add-on. You give us a list of names, places and terms with how they should sound, and we tune each one. Test calls let you hear them in real sentences before the voice goes live.

Can you clone my own voice or a staff member's voice?

No, not within this add-on. Voice cloning raises consent and platform-policy questions and needs a separate scope. This add-on chooses from the voices your platform provides and tunes them. If you need a cloned voice, ask for a Change Quote at checkout.

Will a different voice cost more per minute?

Sometimes. Some platforms price premium voices higher than standard ones. When we prepare the shortlist, we tell you if any voice carries a different per-minute rate, so you can choose with the running cost in view. Those minutes are billed to your own account.

Can the voice be changed on an agent already taking calls?

Yes. The shortlist and tuning are done on test calls, and the new voice replaces the old one only after you approve it, so live callers never hear a half-tuned voice. If you are buying the agent now, tuning follows its delivery speed. Each speed has a fixed price and date shown before you pay.

Can the speaking speed differ for different parts of a call?

Yes, within what your voice platform supports. Many teams slow the agent down for addresses, times and confirmation numbers while keeping greetings at a natural pace. We tune those moments during testing and you hear them on the test calls before approving.

Give your voice agent a voice that fits.

Add Custom Voice Selection and Tuning and you choose from a shortlist, then hear your names and terms said correctly on test calls before launch.
