Open the original- What it measures
- The setting is changed with /config or directly in the settings file, and you can give either a BCP 47 code such as ja or a language name such as japanese. A language that is not on the supported list falls back to English when you run /voice.
- What it does not show
- The documentation does not say whether the fallback warning also appears in the desktop app. It describes the terminal CLI and the VS Code extension.
