From the developer:
OS X Mountain Lion has a useful new feature: Dictation. However, if you write a lot in different languages, switching between them is quite tedious, because the setting is buried in System Preferences. DictationSwitcher is a little utility that sits in your Mac’s menu bar and makes using Dictation much easier. You can quickly switch between dictation languages, without the need of going through System Preferences.
