$General Motors(GM.US)$ plans to expand its OnStar Guardian emergency services from an in-vehicle feature and phone-based app to at home with $Amazon(AMZN.US)$ Alexa. The company said it will launch a new skill for Amazon’s popular voice assistant that allows subscribers to connect with OnStar emergency-certified advisors by saying, “Alexa, call for help.” For GM, the expansion is a small step in its growth strategy to build relationships with customers beyond vehicle ownership.
