This is according to a report from The Information (paywall), it claims that both Google and Huawei were developing the smart speaker together for at least a year, where it would have been powered by Google Assistant. It’s not surprising that both companies were working together, especially since they both have a close relationship with each other.
In the past, Huawei and Google have worked together on other products, like the Nexus 6P smartphone. It is unclear as to what kind of features this smart speaker would have and how it would have been different from other smart speakers. However, since it has been cancelled, it looks like we will never know.
The report goes on to add that both companies were also working together on how to make Huawei smartphones compatible with Android Auto. In the meantime, Huawei has managed to get themselves out of trouble (sort of) where US companies are allowed to do business with them again.
