Murmur: features, pricing and alternatives

About Murmur

Murmur is a native Mac app for generating speech locally. You write or import a script, choose, clone or design a voice, and export finished audio as WAV or M4A. It runs on Apple Silicon under macOS 15 or later, and the site says audio is generated on your machine and never leaves it.

It includes voice cloning, voice design from a short description, more than 860 community voices and multi-speaker projects with a timeline, plus batch export and a command line and MCP option. The site lists support for over 600 languages, and notes that cloning and voice design need 16 GB or more of memory and extra model downloads.

Pricing is a single $49 purchase covering one Mac with no per-word fees and unlimited generation. The app is Apple notarized, a 7-day money-back guarantee is offered, and team licenses and Jamf and MDM setup guides are listed.
