Amazon, the biggest online marketing company has a brand of smart speakers called 'Amazon Echo' that connects to an intelligent command-controlled personal assistant service known as 'Alexa'. This is a kind of similar functionality like Google Assistant. The word 'Alexa' is like the activating keyword for the system to enable its functionalities. Different functionalities of this device comprises of interaction and operations using voice commands, setting alarms, playing musics, making to-do list, weather forecast, podcasts streaming, traffic and other real-time information. This device acts as an automation hub for home as it can connect and control several other smart devices. But such amazing smart device can sometimes cause serious problems and threats as their artificial intelligence system cannot completely match with human intelligence.

Recently, a woman in Oregon's largest city Portland reported that she received a phone call from one of her husband's employee claiming that he received a audio file containing personal Conversation of their house regarding hardwood floors. This is really shocking and an invasion of privacy for the woman whose entire house is connected with this device. Amazon also confirmed the mishap that the private conversation had been unintentionally recorded by the device and send to random person of the woman's contact list. As explained by the company, the device may have activated itself from word in background conversation which it has interpreted as 'Alexa' and then maybe some another words which it has interpreted as request for recording and sending the message. The 'Alexa' may have responded asking for contact name and it has again interpreted the background conversation with a name similar to someone in the contact list of the women. It may have got confirmation again in same manner after which the recorded audio has been sent. This incident reflects that there is immense need of improvement and training in the artificial intelligence systems of Amazon or these type of incidents may cause serious threat to someone in future.
