Update: New voices and testing capabilities in the AI Assistant Builder

Your AI assistant’s voice sets the tone for every interaction, and now you have more control than ever before. With full access to our voice library, support for custom ElevenLabs voices, and a built-in voice playground, it’s easier to design conversations and deploy agents that sound exactly the way you want.

What’s new:

We’ve upgraded the voice configuration experience in the AI Assistant Builder so you can test, compare, and deploy high-quality voices faster. Additional voices and customizable options are now easily accessible, making it simpler to explore and assign the right sound to your agent.

• Expanded voice access: Use any Telnyx-supported voice, including the full Kokoro language library and dialects.
• Custom ElevenLabs voice support: Bring your own ElevenLabs voice for a fully tailored experience.
• Voice playground: Preview and test multiple voices inside the interface to find the right tone, language, and delivery.

Why it matters

Voice is the first impression your AI assistant makes. Whether you’re serving a global audience or aiming for a specific brand tone, the right voice makes interactions feel more natural and trustworthy. These updates give you full control to fine-tune your assistant’s sound with zero limitations.
