Localization is one of the things that Google does to gain popularity with international users. With 124 languages available for the main Google search product, the Mountain View, CA company is also working on bringing other services to different language.

The latest foray into mutlilinguals involves Voice Search, with 29 additional languages introduced just this week. Now, Google introduces 47 new languages to its Gmail autocomplete search.

The concept is pretty much like autocomplete on the main search product. Type in your query, and the search box makes recommendations based on popular searches and based on your previous search activity. With the update, autocomplete for Gmail search works on languages. More languages are planned in the next few months, including right-to-left languages.

Do you use Gmail in a non-English interface? Is autocomplete helpful, or does it seem too intrusive, since it basically guesses what you want to say?
