Your agent's voice is its first impression. Callers decide in the first few seconds whether your AI voice agent sounds like your business or like a machine reading a script, and the difference usually comes down to one good pick in the voice catalog. This walkthrough follows the video above through the whole choice: previewing voice cards on the agent's Overview, searching a library of 300+ voices by accent, gender, age, and tone, describing the voice you want in plain English, and giving every language its own voice. By the end, your agent sounds the way you meant it to.
Key Takeaways
- Voice selection lives on the agent Overview under Languages and voice: press play on any card to preview it, click a card to set it, and the highlighted card is the voice your callers hear.
- Browse all voices opens the full catalog of 300+ voices, with filters for language, accent, gender, age, tone, and use case, plus search by name.
- You can skip the filters and describe a voice in plain English, like "a warm, friendly younger woman" - Flowyte turns your words into filters and returns a ranked shortlist to audition.
- Every language gets its own voice: English keeps one pick, Spanish gets another, and the agent switches voices automatically the moment a caller changes language mid-call.
- The Assist can do the choosing for you - tell it the voice you want, and it searches the catalog, sets the voice, and keeps shortlisting until it sounds right.
Where Do You Pick Your AI Voice Agent's Voice?
Everything lives on the agent's Overview, under Languages and voice. The cards you see there are the voice catalog: press play on any card to hear a preview, and click a card to make it your agent's voice. The card with the highlight is the voice your callers hear on the next call.
Above the cards sit the language chips. The one marked primary is the language your agent greets in, and its voice is the default voice - every call starts there. If you don't have an agent yet, draft one by describing it in plain English first; Flowyte includes a starting voice you can swap in seconds.
Each card tells you what you're auditioning before you press anything: the voice's name and character, its gender, accent, and age, and the other languages it speaks. Most people find a fit right here. When you don't, the full library is one click away.
Want to hear voices before you build anything? The voice sampler on the voice feature page carries 20 of them - press play, no signup needed.
How Do You Search a Library of 300+ Voices?
Click Browse all voices and the full catalog opens - already filtered to the language you're choosing for. From there you have four ways to land on the right one.
| Way to pick | How it works | Best for |
|---|---|---|
| Cards on the Overview | Press play to preview, click to set | A fast pick from a curated set |
| Browse all voices | Filters for accent, gender, age, tone, and use case, plus search by name | Narrowing 300+ voices with specific criteria |
| Describe a voice | Plain English in, real filters and a ranked shortlist out | Knowing the sound but not the settings |
| Ask the Assist | It searches, sets the voice, and keeps shortlisting | Skipping the browsing entirely |
Every filter shrinks the list as you go, and you can pin your favorites to compare - the compare tray holds up to three voices side by side, so you choose by listening instead of settling. If you already know a voice by name, the name search jumps straight to it.
What if you'd rather describe the voice than filter for it?
Skip the filters entirely and type what you're imagining: "a warm, friendly younger woman." Flowyte turns your words into real filters - you can watch them land as chips - and hands back a ranked shortlist to audition. In the video, that one sentence narrows the Spanish catalog to three candidates, and one click on Milly settles it.
How Does Every Language Get Its Own Voice?
In Flowyte, every language gets its own voice. Open the add-language menu, pick one - the video adds Spanish - and it slots in right next to English. A new section appears: a voice for each language.
English keeps the voice you picked. Spanish just says "choose" until you give it one. Click choose and the catalog opens filtered to Spanish speakers, so every candidate can actually carry the conversation. Set it, and you have one agent with a native voice for every caller.
On a real call, the agent answers in the primary language, in its default voice. The moment a caller switches to Spanish, Flowyte detects it, and from the very next reply the agent is speaking Spanish in the Spanish voice. No settings, no transfers - it just switches. The full setup, including how detection works turn by turn, is covered in the multilingual voice configuration guide. That automatic follow-the-caller behavior is a big part of what makes one number work as a 24/7 AI answering service for a bilingual customer base.
Can the Assist Choose a Voice for You?
Yes. If you'd rather not browse at all, ask the Assist - the chat panel that configures your account for you. In the video, the request is one sentence: find a calm, deeper male voice for English, and set it. The Assist searches the catalog, picks a voice named Archer, and applies it to the agent.
You can be as picky as you like. Tell it the pick is too formal, too bright, or too young, and it keeps shortlisting until it sounds right. Under the hood it's using the same catalog search and per-language voice map you just saw, so anything it sets is exactly what you'd have set by hand.
How Do You Set Your Agent's Voice, Step by Step?
Open your agent's Overview
Scroll to Languages and voice. The voice cards, the language chips, and everything else in this guide live in this one section.
Preview the curated cards
Press play on any card to hear it. Click a card to set it - the highlighted card is the voice your callers hear.
Check your primary language
The language chip marked primary is the one your agent greets in, and its voice is the default. Every call starts there.
Open Browse all voices when you want the full catalog
The library opens already filtered to the language you're choosing for, with 300+ voices behind filters for accent, gender, age, tone, and use case - or search by name.
Narrow the list your way
Stack filters, or describe the voice in plain English and let Flowyte convert your words into filter chips and a ranked shortlist.
Compare your favorites, then click to set
Pin the contenders and audition up to three side by side. One click sets the winner.
Give every language its own voice
Add each language your callers use, then fill each "choose" slot from its language-filtered catalog. The agent switches voices automatically when callers switch languages.
Publish when it sounds right
Every change saves to your draft as you go and ships when you publish. Advanced voice settings sit below the cards - stability, style, and speed, showing only the knobs your chosen voice supports.
Everything above works through the API too: search the catalog and set a voice per language, one call each. The Flowyte developer docs cover both endpoints.

Video transcript
Your agent's voice is its first impression - so let's give it a great one. In this deep dive: how voices work in Flowyte. Picking a voice, previewing the catalog, giving every language its own voice, how the agent switches mid-call - and how the Assist can do the choosing for you.
Everything lives on the agent's Overview, under Languages and voice. The cards you see are the voice catalog. Press play on any card to hear a preview, and click a card to make it your agent's voice. The one with the highlight? That's the voice your callers hear.
And notice the language chips up top. The one marked primary is the language your agent greets in - and its voice is the default voice. Every call starts there.
Now let's go multilingual. Open the add-language menu and pick one - we'll add Spanish. It slots in right next to English, and a new section appears: a voice for each language.
Because in Flowyte, every language gets its own voice. English keeps the voice we picked. Spanish just says 'choose' - so let's find it a great one.
Click choose, and the full catalog opens - already filtered to Spanish speakers. Hundreds of voices, with filters for accent, gender, age, tone, even use case. Preview anything, compare your favorites, or search by name.
Or skip the filters entirely, and just describe the voice you want: 'a warm, friendly younger woman.' Flowyte turns your words into real filters - watch them land as chips - and hands back a ranked shortlist to audition.
We'll take Milly. One click, and it's set. English has its voice, Spanish has Milly - one agent, with a native voice for every caller.
So what happens on a real call? The agent answers in the primary language, in its default voice. The moment a caller switches to Spanish, Flowyte detects it - and from the very next reply, the agent is speaking Spanish, in Milly's voice. No settings, no transfers. It just switches.
And if you'd rather not browse at all - ask the Assist. We told it: find a calm, deeper male voice for English, and set it. It searched the catalog, picked Archer, and applied it for us. You can be as picky as you like - it will keep shortlisting until it sounds right.
Every change saves to your draft as you go, and ships when you publish. And all of this works through the API too - search the catalog, set a voice per language - one call each.
That's voices in Flowyte. Preview and pick from the catalog. A voice for every language. The primary language starts the call - and mid-call, it switches on its own.

Common Questions
How many voices can an AI voice agent choose from in Flowyte?
The voice library holds 300+ voices across 30+ languages. You can narrow it with filters for language, accent, gender, age, tone, and use case, search by name, or describe the voice you want in plain English and get a ranked shortlist.
How do I hear a voice before my agent uses it on a real call?
Press play on any voice card for an instant preview, and pin up to three favorites in the compare tray to audition them side by side. If you have not signed up yet, the voice feature page has a sampler with 20 voices you can play right on the page.
Can I describe the voice I want instead of using filters?
Yes. Type a plain-English description like "a warm, friendly younger woman" and Flowyte converts it into real filters, which appear as chips, then returns a ranked shortlist to audition. One click sets your pick.
Can each language have a different voice?
Yes, and for a multilingual agent you should expect to use this. Each language your agent speaks gets its own voice slot, filled from a catalog filtered to speakers of that language, and the agent switches voices automatically when the caller switches languages mid-call.
Can Flowyte pick the voice for me?
Yes. Ask the Assist for what you want, such as a calm, deeper male voice for English, and it searches the catalog, sets the voice on your agent, and keeps shortlisting until you are happy with the sound.
Do voice changes go live as soon as I make them?
No. Every change saves to your draft as you go and only ships when you publish, so you can audition freely without affecting live calls. Voice search and per-language voice assignment are also available through the API, one call each.
Give Your Agent a Voice Worth Answering In
The whole choice takes minutes: preview the cards on the Overview, open the full catalog when you want more, filter or describe your way to a shortlist, and give every language its own voice. The primary language starts the call, and mid-call the agent switches on its own. Whether you're setting up a conversational AI voice agent for a support line or an AI receptionist for a small business, the voice you pick here is the one that answers every call. Voice minutes start at $0.11 per minute pay-as-you-go, where 1 credit equals $0.01 - current plans are on the pricing page. The fastest next step is to listen: press play on a few cards and pick the one that sounds like you.
