Although the feature has been available for some time for English speakers, Google Search (aka Google Now) will now respond to queries in Japanese, German and French. You'll need the latest Google Search app installed, but once that's done you'll be able to ask questions in the three new languages and receive spoken results in the same language.
Naturally Google can't guarantee that you'll receive spoken results for every voice query, but that's already the case for English as well. You can expect the app to speak back to you when receiving results from the "knowledge graph" that returns a card at the top of the results.
While this is a big deal for those living in Japan, Germany and France, it could certainly be of use when traveling to those countries as a non-native speaker as well. Pair this up with Google Translate and you may have an easier way finding things in a new place.
