Google Duplex: Revolutionary Breakthrough at Machine Learning


               Over the past decade, tech industries have been spending millions of dollars for the advancement in machine learning. It has been a popular research topic for various scientists. As making computer predict possible outcomes and act to it without being explicitly programmed is both interesting and difficult task to do.
Recently during Google I/O conference, Google previewed some added skills of Google Assistant. Various new features were revealed like there will be six new voices for Assistant. But the thing which shook the tech industry was Google Duplex. Google Duplex is capable of having a natural conversation with a human. The CEO Sundar Pichai showed a demo where it was able to handle task over a phone. Google Duplex scheduled a hair appointment through a phone call and receiver had no clue that she was talking to a computer. Some people are saying that google duplex may have passed the Turing Test. Turing test is used to determine whether Artificial Intelligence’s behavior is indistinguishable from that of the human.

The Google Duplex is using Recurrent Natural Network (RNN) to cope up with various challenges. It is built using TensorFlowExtended (TFX) which is a machine learning platform. It uses Google’s Automatic Speech Recognition (ASR) technology to understand the audio. For sounding natural Google uses the combination of concatenative text to speech (TTS) engine and a synthesis TTS engine, which help to control intonation depending on the circumstance.

In the present context, mobile technology is the fastest growing industry. Google duplex helps mobile technology to take even further leap in advancement. If this rate continues what more can we expect in the future? We are the same generation who used small black and white mobile devices and now we are using smartphones bursting with Intelligence and machine learning. This development raises various questions in people’s mind like what more can we expect? Is talking to a person without having their consent a good thing? Is Google violating people’s privacy? These are some genuine questions which need serious discussion.
