In this step, you can customize your voice agent’s identity and behavior by setting its name, language, voice, personality, and timezone.

​
Agent Names, Languages & Voices

To define your agent’s identity:
  • (1) Agent Name – Give your agent a name (e.g., Joa, Victoria). This name helps humanize the interaction and reflect your brand identity.
  • (2) Language – Select the default language your agent will speak. This ensures accurate pronunciation and localized expressions.
  • (3) Voice – Choose the voice that will represent your agent. You can preview voices and select the one that fits your tone.
Agent Names, Languages & Voices section
You can set up your Pearl to support multiple languages by adding several agent configurations, each with its own name, language, and voice. When a caller asks to switch language mid-conversation, Pearl automatically reroutes the call to the agent for that language. The first agent you create is the Default Agent and always opens the conversation, unless another language is requested. You can add more agents directly in the table.
Explore Voice and Language to view all the language options available.

Pearl Model

The Pearl Model defines the intelligence, speed, and cost profile of your agent. Voice agents can choose from four models.
Pearl Model selection in Pearl Settings

Highest Quality · Higher latency · +2 credits/min
Our smartest model, built for demanding use cases that require deeper reasoning, stronger understanding, and the highest-quality responses.Use it when you need:
  • The deepest reasoning for complex, multi-step conversations.
  • Maximum nuance and understanding on high-stakes or ambiguous calls.
  • The best possible answer quality, even if it means slightly higher latency.
Choosing the right model for your Pearl When selecting a model, consider three main dimensions:
You can use different models for different Pearls depending on their role, volume, and business impact (for example: Hydra for the most complex high-stakes calls, Arrow for VIP inbound support, Trident for main support, Oyster for large reminder campaigns).
Start with Pearl Trident as a balanced default, then use Analytics to compare performance and cost. If you need more speed or nuance, move to Pearl Arrow; if you need to optimize budget for simple flows, switch to Pearl Oyster.

​
Personality

Your AI agent can take on a wide range of personalities, from natural and professional to wild, fictional, or downright iconic.
Personality selection in Pearl Settings
Create your own personality. You’re not limited to the predefined list. Type any description in the Personality field and select Use “<your text>” as a custom personality to define your own.
Choose wisely. Your agent’s personality will shape how it sounds and behaves in every interaction. Personality is optional, only Agent Name and Timezone are required.
The personalities below are examples to give you a feel for the range available. The full list is loaded in the app and may evolve over time.

​
Timezone

Define the timezone of the agent. This influences time-related actions, such as booking meetings.
