INSUBCONTINENT EXCLUSIVE:

conference Google says it will take steps to ensure that humans are not fooled when they get called by software bots that
can convincingly mimic the human voice
Anyone called by the bot will be told they are conversing with a machine, Google told tech news site the Verge.The vocal skills of the
Duplex bot were demonstrated at Google's I/O developer conference this week when it was shown booking a hair appointment.The demo left one
technology expert "horrified" by what she had seen.In its statement, Google said it valued the discussion the demonstration had fostered and
said "transparency" around the use of the technology was important."We are designing this feature with disclosure built-in, and we'll make
sure the system is appropriately identified," it said.The on-stage unveiling involved the Duplex software conducting a conversation with a
hair salon receptionist
The computer-generated voice used pauses, colloquialisms and circumlocutions usually present in human speech.The voice was under control of
Google's DeepMind WaveNet software that has been trained using lots of conversations so it knows what humans sound like and can mimic them
effectively.Google said the software was developed to have "natural" conversations and would be able to accomplish real-world tasks for
people via their phones
In its statement, Google said it welcomed feedback about the project that would be used to fine-tune the finished version.The demo was
called "horrifying" by Zeynep Tufekci, an associate professor at the University of North Carolina who regularly comments on the ways
technology and society impact on each other.In a tweet, Prof Tufekci said the idea of mimicking human speech so realistically was "horrible
and obviously wrong".In a later comment, she added: "This is straight up, deliberate deception
Not okay."Prof Tufekci said she was surprised that the WaveNet project got as far as a public demonstration and wondered why it had not been
quashed internally during development
