DraftFrequently asked questions
Is Murmur Voice Design the same as voice cloning?
No. Voice Design starts from a written role and speaking direction. It is for creating reusable production voices, not copying a specific person's identity.
Does Voice Design run locally?
After the model is installed, generation runs on your Apple Silicon Mac inside Murmur, so scripts and previews stay in your local workflow.
What should I write in a voice prompt?
Describe the role, age range, accent, tone, pacing, texture, and where the voice will be used. Murmur includes prompt recipes so you do not have to start from a blank box.
Can I reuse a designed voice?
Yes. Save the best preview to My Voices and assign it again in scripts and projects.
Build a role voice once. Reuse it in Murmur.
Design the role, preview the take, and keep the voice inside the same local Mac production workflow.
