The SN54 / 74LS113A offers individual J, K, set, and clock inputs. These
monolithic dual flip-flops are designed so that when the clock goes HIGH, the
inputs are enabled and data will be accepted. The logic level of the J and K
inputs may be allowed to change when the clock pulse is HIGH and the
bistable will perform according to the truth table as long as minimum setup
times are observed. Input data is transferred to the outputs on the
negative-going edge of the clock pulse.

语音作为自然的人机接口，可以使车载导航系统实现更安全、更人性化的操作。通过国内外车载导航系统的功能对比可知，支持语音交互是车载导航系统的一个发展趋势。另外，市场信息服务公司J.D Power and Associates的调研数据也表明，56％的消费者更倾向于选择声控的导航系统。因此，开发车载语音导航系统是很有意义的。目前，国内已经具备开发车载语音导航系统的技术基础，特别是文语转换TTS技术...[详细]
