This paper investigates the implementation of voice-enabled Google Assistant and Amazon Alexa on Raspberry Pi. Virtual Assistants are being a new trend in how we interact or do computations with physical devices. A voice-enabled system essentially means a system that processes voice as an input, decodes, or understands the meaning of that input and generates an appropriate voice output. In this paper, we are developing a smart speaker prototype that has the functionalities of both in the same Raspberry Pi. Users can invoke a virtual assistant by saying the hot words and can leverage the best services of both eco-systems. This paper also explains the complex architecture of Google Assistant and Amazon Alexa and the working of both assistants as well. Later, this system can be used to control the smart home IoT devices.

In a recent study by Gartner Reports, the analyst estimated that by 2020 the average person will have more conversations with bots than with their spouse. The report failed to clarify if this was attributed solely to increasing dependence on AI technology, or if deteriorating spousal relations played a role as well. I suppose it could be a blend of both. What is clear is that there is an inevitable trend moving from screen interfaces to chat interfaces that has all major tech companies scrambling to ensure they have a place at the table in this AI assistant future. It is no exaggeration to say that the business models of most major tech companies rely heavily on users looking at a screen.

Apple announcements are like holidays in our office, and the new iOS release in September was no exception. Since then, AI assistant news has moved at warp speed. Every Alexa update is a new opportunity for fintech integration. Google, with its latest releases, is also now in the running. Add to this Bank of America's launch of a new AI chatbot, Erica, at Money 20/20 in Las Vegas, and the bank bot race is on.

Google Assistant, the search giant's new personal digital assistant, is barely available to users, but Google isn't wasting any time opening it up to developers. During the company's hardware event on Tuesday, Google announced two new developer programs to build Google Assistant into pretty much anything you can think of. "Going back to Google's earliest days we've always worked hard to create healthy open platforms," said Scott Huffman, who leads the Google Assistant engineering team. "The Google Assistant will be our next thriving open ecosystem." The first new program is called Actions on Google, which will launch in early December and allow app makers to build Google Assistant into their services.
