Marriott recently teamed up with Amazon to offer a hospitality version of the e-commerce giant’s Echo devices in select hotel rooms. Now, when guests want to order room service or housekeeping, they can simply ask Alexa, the voice of their disembodied personal concierge. Travelers with an Alexa device at home can book a car rental or hotel through Expedia and Kayak. Similarly, Google Assistant, which can be used via Google Home devices, smartphones, or smartwatches, can track flight prices and status, suggest nearby restaurants, convert currency, give directions, and provide same-day updates on traffic to airports. People can even book flights through voice-enabled Google Search.
