An AI voice is computer-generated speech produced by a text-to-speech system. It is the audible layer of a voice agentVoice agentA voice agent is a conversational software system that listens, responds, follows a defined workflow, and can take approved actions during a phone conversation.: the conversation system decides what to say, while the voice model determines how that response sounds. An AI voice may be selected from a licensed library or created from an authorized voice sample.
What an AI voice controls
Voice choice affects pronunciation, pacing, tone, language, and how consistent the experience feels across calls. It does not determine the agent's business rules, knowledge, or routing logic. Those belong to the conversation flowConversation flowA conversation flow is the designed path through greeting, intent capture, qualification, actions, routing, fallback, and closing., prompts, connected data, and guardrailsGuardrailsAI guardrails are instructions, rules, data boundaries, and escalation paths that constrain what an agent may say or do.. Thoughtly lets teams browse and preview voices in the Voice Selector, then assign a voice and language in agent settings. The Voice Library also supports licensed and cloned voice options.
Practical use cases
- Match the speaking style to a brand, audience, or region.
- Keep the same voice across qualification, booking, and follow-up calls.
- Test pronunciation of names, numbers, product terms, and required disclosures.
- Use an authorized custom voice when brand consistency requires it.
A realistic voice does not excuse unclear disclosure or poor conversation design. Teams should test real calls for mispronunciations, interruptions, timing, and background-noise behavior before launch.
