Voices control how your AI agent sounds on the phone:
  • The language and style of speech
  • How natural or synthetic the audio feels
  • The perceived “personality” of the agent
You can:
  • Browse and listen to available voices
  • Search by name and filter by provider or source
  • Import new voices from supported providers (after adding an API key)
  • Assign voices to your agents so every call sounds consistent with your brand

How voices fit into Fluents.ai

Think of a voice as part of your agent’s identity:
  • Agent = what the agent says and how it behaves (prompt, rules, logic)
  • Voice = how the agent sounds when speaking
You can reuse the same voice across multiple agents, or choose different voices for different roles. For example:
  • A friendly, neutral voice for after‑hours reception
  • A more energetic voice for outbound sales
  • A calm, reassuring voice for support or sensitive conversations
There is no separate tone slider in Fluents.ai today—the tone and style come from the specific voice you choose.

Browsing and filtering voices

In the Voices section of Fluents.ai, you’ll see a list of all voices available in your account. Typical fields include:
  • Name – The display name of the voice.
  • Provider – Which voice provider or engine the voice comes from.
  • Source / created by – Whether the voice was added by Fluents.ai or imported/created by your account.
You can:
  • Search by name to quickly find a specific voice.
  • Filter by provider to see only voices from a given provider.
  • Filter by source (for example, platform voices vs. voices you imported yourself).
This makes it easy to:
  • Find platform voices that work well out of the box.
  • Focus on voices from a specific provider if you have a preference.
  • See only the voices your team has added.

Importing new voices (via provider API key)

If you use an external text‑to‑speech (TTS) provider, you can import new voices into Fluents.ai. There are two main steps:
  1. Connect your provider in the Providers tab
    • Go to the Providers section.
    • Select the voice provider you want to use.
    • Add your API key / credentials for that provider.
    • Save the configuration.
    If no provider API key is configured, you cannot import voices from that provider. For a detailed walkthrough, see the
    Providers Feature Guide (for example: “How to connect a voice provider”).
  2. Import voices in the Voices tab
    • Go to the Voices section.
    • Use the Import voices option (or the equivalent action in your UI).
    • Choose the provider you connected.
    • Select which voices you want to import.
Once imported:
  • The new voices appear in your Voices list alongside platform voices.
  • You can select them when configuring an agent, just like built‑in voices.
This is useful if:
  • You already have custom voices with a provider.
  • You want access to a larger or more specialized catalog of voices from your own provider account.

Testing (previewing) voices

Before assigning a voice to an agent, you can play a short sample of how it sounds. In the UI, you’ll typically see:
  • A Play or Preview button next to each voice.
  • Either a default sample sentence, or an input where you can type a short test phrase.
You might use this to:
  • Compare several voices side‑by‑side.
  • Hear how different providers handle the same sentence.
  • Check pronunciation of names, product terms, or industry‑specific words.
Tip: When possible, test a short sentence similar to what your agent will say on real calls (like your greeting or introduction line).

Choosing the right voice for your use case

Some practical guidelines:
  • After‑hours / reception agents
    • Choose a clear, friendly voice that is easy to understand.
    • Prioritize clarity over strong personality.
  • Outbound sales agents
    • Consider a voice that sounds confident and engaging.
    • Make sure it still feels natural when heard many times.
  • Support or sensitive conversations
    • Prefer a calm, reassuring voice.
    • Test that key terms are pronounced correctly.
You can change an agent’s voice later if you find a better fit—no need to recreate the agent.
