Abstract: This paper presents a novel in-car design to recognise the driver|s voice and to control in-car devices. In a non-stationary noise car environment, a speech recognition kit SR-07 with speech recognition chip HM2007 has less than 10% successful hit-rate. With an adaptive Wiener filter, the successful hit-rate has improved to as much as 75%.

Keywords: Wiener filter; adaptive filtering; automobile industry; noise reduction; in-car design; vehicle design; voice recognition; automotive speech control; in-car devices.
