Open the original- What it measures
- Murmure is a third-party project, not a Microsoft product. The repository describes it as powered by NVIDIA's Parakeet TDT 0.6B v3 model.
- What it does not show
- This is the project's own statement. The README does not say whether the app ever contacts a server, for example to check for updates, so check the release notes and network behavior yourself if that matters.
