Q: Baker's voice will replace the earlier computer-synthesized voice that was previously used. BT said that his voice was chosen as it was instantly recognisable. It took him 11 days to record 11,593 phrases and sounds which could then be broken down and reassembled by a computer to make new words. It then took five months to process these recordings to make a workable service. BT have said that there will be no barriers as to what Tom Baker's voice can 'say', including rude words. "What appeals to me most is the thought that I will be bringing good news to people whether it is a cheeky message, a birthday greeting, or just a quick hello," said Baker.
