Anyone who downloads TweetVox on to their phone can make their "tweet voxes" location-specific. "It gives a voice to a place," says Odriosolo, 30, explaining that users will be able to record a review of a restaurant as they walk out, and tag it for future visitors to hear.
"We're sure that TweetVox's users will appreciate its simplicity, and the added value it will give to their day-to-day usage of social networks."
But Rhodri Marsden, a technology columnist, says Twitter can only work as text. "All the things that are good about Twitter, like the rapid exchange of messages and the ability to track back through a conversation, and the ability to search, none of these exists as soon as you turn it into audio," he says.
"The fact that Twitter is silent is part of its appeal, because peoplecan tweet while they're watching telly, which has become a bigthing."
John Rentoul, chief political commentator of the Independent on Sunday, and a prolific tweeter, is also sceptical, but warned that writing it off could be dangerous.
"It sounds awful," he says. "But then, when Facebook launched, I said it would never take off."
