摘要：
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%.
