AI-Based Voice Assistants Technology Comparison in Term of Conversational and Response Time

With the rapid development of artificial intelligence (AI) technology, the field of mobile phone technology is also developing in the direction of using artificial intelligence. Natural user interfaces are becoming popular. One of the most common natural users interfaces nowadays are voice activated interfaces, particularly smart personal assistants such as Google Assistant, Alexa, Bixby, and Siri. This paper presents the results of an evaluation of these four smart personal assistants in two hypothesis: The first hypothesis is presents the results of an evaluation of these digital assistants in how the application is very good in interacting based on conversation, means in how the app can be able to continue answer questions in depending on the previous answer, and the second hypothesis is to measure how long it take for an app to respond on those conversasion, doesn’t matter if the app was able to keep on conversation or not. To determine this conversation and time taken on those conversation, four apps are install into four Samsung smartphone and defferent continuous question was asked after completed an answer previous question at the same time to all voice assistance. The overall result shows that, Google assistant was able to keep answer question by depending the previous answer without mis any question compare to the other digital assistants respectively but is very slowly app in responding to those conversation. Siri mis to keep on conversation on few question compare to Bixby and Alexa but is first app to respond to those conversation. Bixby was able to keep on conversation only in mathematical question but in other question was very poor but in case of time taken to respond is the thirsd app after Alexa. Alexa keeps on conversation in some question more than Bixby and in term of time taken to respond Alexa is second after Siri.
