Google just updated it support pages for Allo to make it official that the Assistant only other other supported language that English is German. We expect Google to make Hindi Assistant’s third language, as Google has been working quite with some dedication for Indian users these days.
Google also made it official that Smart replies feature in Allo works with Hinglish — that’s a combo of Hindi+English. And it’s crazy good how cool Allo’s smart reply feature works.
