Best Practices

Get the most out of background noise with these recommendations.

Do: Match the Persona

Use "Call Center" for support agents, "Office" for business assistants, "Café" for casual chatbots.

Do: Keep Volume Low

Background noise should be subtle. If it's distracting, it defeats the purpose.

Do: Test Before Deploying

Always make test calls to ensure the noise level and type work well with your voice.

Don't: Use Distracting Sounds

Avoid loud or jarring sounds like "Construction" or "Arcade" for professional calls.

Don't: Mismatch Context

A medical support agent shouldn't sound like they're at a café.

Don't: Overuse Weather Sounds

Rain and thunder can mask speech. Use sparingly and at low volume.
