语音识别
Speech recognition can be installed during Office XP setup or by clicking the Speech option in the Tools menu in Word 2002. When installed, it is available as a Microphone command on the Language toolbar that appears in the upper-right corner of the screen (lower-right corner in East-Asian versions of Office XP). When launched for the first time, speech recognition offers a tutorial to improve recognition accuracy, which begins by providing instructions to adjust the microphone for optimal performance. Speech recognition uses a speech profile to store information about a user's voice.
