Unbabel Interface for chat includes a feature that allows the tool to recognize the language from the text contained in the message box, in order to automatically and appropriately set the correct translation direction by changing the source and target languages. This is the language detection feature.
The feature can be toggled on and off by clicking the "magic wand" icon left of the language switcher. When active, the icon will be blue, contrary to its grey counterpart when the feature is off.
When language ID is occurring, a circle around the magic wand icon will move around, and stop when the process is complete. If successful, the language will be selected and highlighted above the message window. If not, the previously selected language will remain the same - the icon will shake if the process fails.
Language detection is a fast process but it will still take a couple of seconds running the identification, so please refrain from hitting the send message button immediately, or you will risk submitting the request in the wrong direction. Also, bear in mind that the bigger the text, the longer the process may take.
The language detection feature requires a minimum of words (usually 3 to 4) in order to be able to properly detect if the language in use is English or the chat language. It is only available for chats using English in the language pair and restricted to German, Spanish, French, Italian, Japanese, Dutch, Polish and Portuguese for the time being.
