### Answer
I don't have information about dynamically changing the voice for each call in the available sources. The sources discuss dynamic variables for personalizing agent responses with data like customer names and order IDs [(1) ](
) , but don't specifically cover changing voice settings per call.
I could try to answer generally if you'd like, but I recommend checking these potentially useful sources:
- [Dynamic Variables](
)
- [Platform Changelogs | Retell AI](
)
You can also visit [Documentation](

) for more specific guidance on voice configuration options.
