Overview
Open Voices from the AI Phone Agent menu ("Browse and preview available AI voices"). The library is read-only: you listen to voices here, and you pick them for an agent in the agent editor. Every member of your organization can open the Voices page.
All voices are provided by VINSI.AI, so the Provider column always shows VINSI.AI. The list includes the shared voice library plus any custom voices VINSI has added for your organization.
Browse the Voice Library
The library is a table with 10 voices per page (you can switch to 5, 25, or 50). Click a column header to sort.
| Column | What it shows |
|---|---|
| Preview | Play/pause button for a sample of the voice. |
| Voice Name | The name you'll see in the agent editor. The person icon is blue for male, pink for female, and gray for unknown. |
| Gender | Male, Female, or blank if unknown. |
| Provider | Always VINSI.AI. |
| Description | Style and best use (for example accent, age, or tone). Hover to read a long description. |
| Languages | A flag for each language the voice supports. Hover a flag to see the language name. |
On a phone, voices appear as cards with the name, gender, description, and a play button.
Search and Filter
- Search by name or description... — type part of a voice name or a word from its description, such as British, calm, or narration.
- Gender filter — choose All Genders, Male, or Female.
Preview a Voice
Click the play button in the Preview column, or click anywhere on the row. Click again (pause) to stop. Only one preview plays at a time — other play buttons are disabled until the current sample ends or you stop it.
Previews are high-quality audio. On a phone call the voice sounds a little narrower, so test your final choice with Talk or Call Me in the agent editor.
Use Voices in an Agent
- Open AI Phone Agents and click Edit on an agent (or create one).
- Choose the Inbound Agent or Outbound Agent tab. Each direction has its own voices.
- In the Settings panel, open 🎙 Voice. In AI Voices, pick one or more voices from the list ("Select a voice..."). Remove a voice with its ×.
- Or click Preview to open Voices Preview: the full library with search, gender filter, and play buttons. Tick the Selected checkbox for each voice you want, then click Close.
- Click Save.
Every agent needs at least one voice on each tab. New blank agents start with a default voice already selected. The AI Phone Agents list shows each agent's voice in the Voice column.
The rest of the Voice section — Allow Interruptions and Turn Detection Sensitivity — is covered in Create your first AI Phone Agent.
Multiple Voices: Cycling or Random
When you select two or more voices, Voice Selection Mode appears. The agent picks one voice when a call starts and keeps it for the whole call.
| Mode | How the voice is chosen | Good for |
|---|---|---|
| Cycling (default) | Takes turns through your voices in order, one per call. | An even spread, e.g. A/B testing two voices. |
| Random | Picks one of your voices at random for each call. | A natural "team of receptionists" feel. |
If your welcome message or instructions give the agent a name (for example "My name is Giselle"), pick voices that fit that name and gender, or remove the name.
Custom Voices
There's no self-service voice cloning or upload. If you need a specific or cloned voice (for example your brand voice), contact VINSI support. Once it's added for your organization it appears in the Voices page and in AI Voices like any other voice, and only your organization can see it.
Choosing a Voice
- Check the Languages flags match the agent's Language (in 🧠 Knowledge).
- Pick a calm, clear voice for support and healthcare; a brighter voice for sales and hospitality.
- Use the same voice for inbound and outbound if callers should recognize your agent.
- Test with a real phone call before going live.
Troubleshooting
