While Assistant already works with more than 70 smart home device makers, the company announced that it will soon release an Assistant SDK so that developers hardware manufacturers can integrate the service into even more devices -- anything from speakers to blenders, smart locks to web cameras. "The new Google Assistant SDK easily allows a manufacturer to build the Google Assistant into any hardware," Google's Scott Huffman told the crowd.

Assistant also boasts a number of new features when it arrives on those devices. Google also said that Assistant will speak four additional languages (French, German, Portuguese and Japanese) come summer and allow users to shop on third-party websites without having to install separate apps or even open a new browser window. What's more, Assistant now understands written and typed queries in addition to verbal commands so you won't have to shout orders at your phone in public anymore.

Chinese AI company, Mobvoi, also made an appearance to show off its newest Assistant-capable smart home device: the Tichome Mini. Despite not being very well known outside of China, Mobvoi is quickly becoming a key player in the Android Wear space. The company released a surprisingly decent $100 smartwatch running a custom Android-based OS last July, called the Ticwatch 2 . And, just last month, teamed with VW to improve the performance of the automaker's in-car AI system.

"Mobvoi is proud to be one of the Google Assistant's partners," Zhifei Li the company's CEO said onstage at I/O. "We believe that the Google Assistant is capable of delivering compelling user experiences with its years of persistent exploration and accumulated experiences in R&D, as well as core AI technologies."

The Tichome Mini is slated to go on sale at some point later this year, though the price and release date both remain unknown.
