People struggling to follow a conversation in noisy situations could soon be helped by artificial intelligence after a technological breakthrough that claims to have solved the "cocktail party problem".
The phenomenon describes how people can filter out background noises, such as the chatter of a party, to focus on one particular sound or speaker. Scientists have long puzzled over how the human brain is able to do this, leading Tech Crunch to call it "one of the greatest barriers to voice technologies reaching a level of understanding comparable to humans".
Voice technologies, added the website, are a growing market expected to reach $26.8 billion (£20.4 billion) by next year. But they are not being designed to confront the "messiness" or "cacophony" of real life, in particular the background and ambient noise that "muddies" the signals they receive. The only way to combat this, according to Tech Crunch, is to find a way to make voice tech as good as the human auditory system.
It is not only scientists who have been trying to combat background noise; a growing number of people are having problems with the cocktail party problem, reported the i news site. In particular people born between 1997 and 2012, so-called Generation Z, are struggling to hear conversations when in noisy places, it added, citing a survey that found 11.5% of this group "always" experiences the condition, compared with only 8% of 25- to 34-year-olds and 7.4% of over-55s. The researchers believed a greater use of headphones by the younger respondents was the "key reason" for the difference.
The technology is now also being employed by the military and future uses could include smart speakers and hearing aid devices, added the BBC. |
