| 摘 要： | 文章以整车非安全性车身电器为控制对象,给出了一种基于HMM算法的非特定人语音集成控制方案,详述了系统的硬件、软件设计方法,并实现了系统样机的研制。其中,系统语音识别单元是以Soc语音处理芯片SDA80D51为核心,并应用飞思卡尔高性能MCU——MC9S12XEP100作为执行单元主控芯片,实现了对非安全性车灯、自动空调、汽车雨刮、电动车窗和汽车音响的语音识别与集成控制。该系统在样机上进行了车载电器语音控制测试,测试结果表明系统在相对安静环境下的平均识别率可达94%。

| Abstract: | Taking non-safety vehicle devices as the control objects,a design scheme of speaker-independent voice control based on HMM algorithm is put forward.The hardware interface design and the software design are introduced,and the system prototype is developed.The Soc speech processing chip SDA80D51 is applied in the voice recognition unit and the Freescale MCU-MC9S12XEP100 is chosen as the central chip of execution unit.The voice recognition and integrated control of vehicle’s non-safety lights,automatic air-condition,windshield wipers,power windows and audio is implemented.The voice control system of in-vehicle devices is tested on the prototype platform,and the results show that the average voice recognition accuracy rate reaches 94% under the relatively quiet environment. |
