The New Google Assistant

This week’s 2018 Google I/O event showcased the new Google Assistant technology that is more natural and personal than ever.

The technology has been apart of a two year vision to provide progressive technology for people all over the world. The assistive device features voice technology that aims to alleviate errors in computerised conversation that often accompanies current technologies in this field.

The technology known as, Google Duplexis an extension of the Google Assistant and is available to people all over the world on over 500 million devices. The assistive technology will feature more than 30 languages and be available in over 80 countries by the end of the year.

However, what’s most impressive about the Duplex technology is its ability to engage in natural ‘real life’ conversations in the bid to improve interactions with users and businesses.

Common frustrations surrounding computerised conversations can be accredited to the natural pauses, inferred meanings, interruptions and errors in human speech that computer technology is unable to pick up on or reciprocate. In an age of state-of-the-art technology that surrounds most homes and business, Google has recognised this lack of connection and the need to improve human-computer interactions.

The new Duplex technology will enable conversations that will sound natural thanks to advances in understanding, interacting, timing, and speaking.”

Built using TensorFlow Extended (TFX), the Duplex system is designed to cope with the challenges of natural speech as a recurrent neural network (RNN).

The technology is built to complete specific tasks such as scheduling appointments. For such tasks the conversational experience must flow as natural as possible in order to avoid the person receiving the call having to adapt their conversation to speak to a machine.

We trained Duplex’s RNN on a corpus of anonymised phone conversation data. The network uses the output of Google’s automatic speech recognition technology, as well as features from the audio, the history of the conversation, the parameters of the conversation and more.” Says Google.

Aspects of the technology that improve the ‘natural’ conversation include the use of “umms” and “hmms” to mimic human speech.

Whilst Google inspires excitement around the technology, critics have taken to Twitter to express their concerns.
