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.
InstantTranslate makes it really easy to translate a selection of text in the application you are working in from one language to another language.
One World Dictionary by Ascendo is a leading multilingual reference tool for Apple desktops.
