I could imagine trying to capture and analyze at least a few words leading up to the trigger word of 'Alexa' to help make it more accurate. Even if the trigger word is Alexa, different languages, dialects, and slang might vary quite a bit. Some significant portion of people might use "Yo, Alexa...", vs "Hey Alexa...", vs. <a second or two pause> "Alexa...". I'm sure someone with a spouse or child named "Alex", "Alexander", "Alexandra" and so on might also trigger it by accident a bunch, e.g. "Alex, uh, who called?". Matching all of those trigger patterns would help filter out false positive matches, or take false negatives and refine them so more people can use the product with their own language style and be less frustrated.
