According to the voice service's developer preview page, any device with a processor, a microphone, a speaker and a network connection has compatible hardware. With the Alexa Voice Service, a developer can add voice recognition capabilities to any device that has compatible hardware. The Echo device is a black, cylindrical tower, about 25 cm tall, that lives in your living room and waits for you to activate it by saying its wake word, which is either "Alexa" or "Amazon."Ĭool as it is, the Echo device is only one example of the use of Amazon's Alexa Voice Service. But, unlike the mobile phone assistants, Echo is hands-free. Like the mobile phone assistants - such as Siri, Google Now and Cortana - Echo answers questions, follows commands, plays music and does dozens of other things when a user talks to it.
Amazon Echo is a new entry among intelligent personal assistants.
