NCT of Cambridge, England has developed new software technology, named, ClearSpeech Xtreme, which will allow mobile phones and Bluetooth headsets to be used in noisy environments.
ClearSpeech Xtreme uses two microphones; one is for speech and other to pick up ambient noise. The ClearSpeech Xtreme uses a DSP (digital signal processor) to remove the ambient noise from the voice signal and enable clear speech to be heard at the receiving end. Currently, microphones run on DSPs from Analog Devices and TI. The technology is also offered in fixed and floating point ANSI C code format.
According to NCT, the ClearSpeech offers the noise reduction, echo cancellation and signal conditioning software. Even the technology can be integrated into audio chips or software applications for providing voice clarity for listeners and speech recognition systems. The company’s ClearSpeech technologies appear to support Windows XP/XPe, Windows CE, Windows CE for Automotive, Linux, and QNX, among other OSes
