News of Google’s shift in approach to Duplex’s transparency was first reported this afternoon by CNET. >Duplex is not yet a working product, and Google CEO Sundar Pichai introduced it onstage on Tuesday at the company’s I/O developer conference with only a pre-recorded phone call. That demo showcased how Google Assistant could sound much more lifelike when making use of DeepMind’s new WaveNet audio-generation technique and other advances in natural language processing, all of which helps software more realistically replicate human speech patterns. For instance, Duplex is so convincingly human because Google includes ticks like “uh” and “um” and other more colloquial phrases into the Assistant’s verbal library.
