Your AI voice matters

The voice that answers your phone is the voice of your brand. When a caller picks up the line, that first greeting sets the tone for the entire interaction, and the impression it creates stays with them. A friendly, clear, and confident voice instils trust and communicates professionalism. Research shows that consistent voice and language across communication channels build stronger brand recognition and deeper connection with customers.  Syllable delivers flawless brand representation across multiple channels.  

Before your AI agent ever speaks with a customer, you can now test its voice directly inside the Syllable Console. The new Voice Test feature lets you listen, adjust, and compare voices instantly - all without running a live session.

No more guesswork or waiting for campaign calls to hear your agent in action. With Voice Preview, you can confirm your tone, pronunciation, and pacing before launch.

How it works

• Go to your Agent  - In the Syllable Console, click on "Agents", select the agent you’d like to hear and click "Preview"

• Start your test - You’ll find a new voice section under "Test your agent", click "Start."  Note: You may need to enable mic and audio permissions

• Listen and adjust - Instantly hear your agent’s voice and listen to it's tone, pronunciation and pacing.

• Verify tool calls - Watch the panel on the right hand side for tool usage and other technical information.
