Amazon.com Inc’s digital assistant appeared almost everywhere at the CES technology show this week in Las Vegas, even making an unexpected appearance on rival Google’s Android system. Companies ranging from appliance maker Whirlpool Corp to Ford Motor Co unveiled products featuring Alexa, the digital assistant from Amazon that responds to voice commands. Most strikingly, Chinese firm Huawei Technologies Co [HWT.UL], which manufactures smartphones running on the Android operating system produced by Alphabet Inc's Google, announced that its flagship handset will come with an app that gives users access to Alexa in the United States.
