AT&T Co’s AT&T Microelectronics unit plans to demonstrate a speech processing chip set – to cost under $18 in volume – at the Winter Consumer Electronics Show in Las Vegas, which it claims can be trained to respond to user commands for hands-free telephone operation, and full-duplex speakerphone that uses the chip set and is claimed to be virtually free of the irritating echo common to most such phones; as well as enabling both ends of a conversation to get through normally, the new signal processor also claimed significantly to reduce the hollow sound on a speakerphone; the new HVP-S chip is an application-specific version of AT&T’s DSP1605 chip; Cincinnati Microwave Inc is incorporating the HVP-S – for Hands-Free Voice Processor with Speakerphone – technology into its 900MHz cordless phone for availability by year-end.
