Google brings ‘Interpreter Mode’ language translation to the Assistant on smartphones

Google introduced its real-time translation feature, “Interpreter Mode,” for Google Home and smart displays earlier this year. It tested the feature in several hotels in Las Vegas, New York and San Francisco at concierge and registration desks.

Now the company is more broadly rolling out Interpreter Mode to Android devices and iPhones. Where there were 26 languages available on Google Home, there are now 44 on the smartphone Assistant.

Google Translate also works. While the capability is impressive, people have been using Google Translate in real-world travel or foreign-language contexts like this for some time. This is just a more elegant and enhanced presentation of Google’s underlying machine translation capabilities.

‘Help me speak [language].’ In order to invoke Interpreter Mode, users say something along the lines of “Hey Google, help me translate [foreign language].” It will then enable real-time translation. Google also says the Assistant “may present Smart Replies, giving you suggestions that let you quickly respond without speaking.”

Interpreter Mode works automatically on Android, but iPhone users will need to install or update the Google Assistant app. Without updating the app, I tried to invoke it on the iPhone, and it prompted me to use the Google Translate app instead. Indeed, real-time translation can be accomplished with Google Translate, though somewhat more awkwardly.

Why we care. As Google continues to add capabilities and features to the Assistant, it reinforces usage and loyalty. The Assistant is Google’s cross-platform UI that spans multiple channels and hardware devices.

Yet we still don’t know how frequently consumers are using the Assistant on smartphones or whether there’s any substitution of the Assistant for more traditional Google Search on mobile devices. I suspect the Assistant as a search alternative is still a small minority use case. Earlier this year Google tested ads in Assistant smartphone search results.
