Google announced a bunch of updates for its Assistant yesterday at I/O, including new ways to interact with Assistant and new voices. The announcements will likely improve the experience of using Assistant, but how do the features stack up against Amazon’s Alexa? We break down each of Google’s Assistant-related announcements from yesterday and how they compare to what Alexa can already do.

Google says that it’ll support more than 30 languages and will be in 80 countries by the end of the year. It also says Assistant is now compatible with more than 5,000 home devices, which is up from only 1,500 in January, and is installed on more than 500 million devices. It’s also in cars from over 40 auto brands.
