Google CEO Sundar Pichai milked the woos from a clappy, home-turf developer crowd at its I/O conference in Mountain View this week with a demo of an in-the-works voice assistant feature that will enable the AI to make telephone calls on behalf of its human owner.

The so-called ‘Duplex’ feature of the Google Assistant was shown calling a hair salon to book a woman’s hair cut, and ringing a restaurant to try to book a table — only to be told it did not accept bookings for less than five people.

At which point the AI changed tack and asked about wait times, earning its owner and controller, Google, the reassuring intel that there wouldn’t be a long wait at the elected time. Job done.

The voice system deployed human-sounding vocal cues, such as ‘ums’ and ‘ahs’ — to make the “conversational experience more comfortable“, as Google couches it in a blog about its intentions for the tech.

The voices Google used for the AI in the demos were not synthesized robotic tones but distinctly human-sounding, in both the female and male flavors it showcased.

Indeed, the AI pantomime was apparently realistic enough to convince some of the genuine humans on the other end of the line that they were speaking to people.

At one point the bot’s ‘mm-hmm’ response even drew appreciative laughs from a techie audience that clearly felt in on the ‘joke’.

But while the home crowd cheered enthusiastically at how capable Google had seemingly made its prototype robot caller — with Pichai going on to sketch a grand vision of the AI saving people and businesses time — the episode is worryingly suggestive of a company that views ethics as an after-the-fact consideration.
