【摘要】：隨著計算機技術的不斷進步和快速發(fā)展，服務機器人的功能也越來越豐富，用戶與服務機器人之間的交互界面也在不斷改善。作為服務器機器人系統(tǒng)的一個重要組成部分，人機交互界面的開發(fā)也越來越重要。人類在與機器人的信息交流中，需要一種更加自然、更加方便的交互方式，而語言作為人類特有的功能，不但自然，而且方便，是人們最理想的人機交互方式之一。 如今的語音技術發(fā)展可分兩個方向：一個方向是大詞匯量的連續(xù)語音交互系統(tǒng)，這些系統(tǒng)都是在計算機平臺上實現(xiàn)的，如語音查詢服務系統(tǒng)；另一個重要的發(fā)展方向是應用于便攜式、小型化的語音產(chǎn)品中，如車載設備的語音控制、手機上的語音撥號、智能家電控制、智能玩具等，這些應用系統(tǒng)大都使用專門的語音芯片來實現(xiàn)。 本文針對是小型化的發(fā)展方向，設計并實現(xiàn)了在ARM嵌入式平臺上的小詞匯量語音交互系統(tǒng)，同時加入了圖形用戶界面，達到一種雙通道互補的交互效果。根據(jù)ARM嵌入式系統(tǒng)平臺的特性和人機交互界面的實際需求，對目標平臺的軟件和硬件系統(tǒng)進行適當?shù)牟眉舳ㄖ�，并且對語音芯片功能進行了優(yōu)化，為實際應用提供良好的人機交互操作。本文首先對嵌入式系統(tǒng)及其Linux操作系統(tǒng)進行研究，然后根據(jù)語音芯片的特點設計了驅動程序和應用程序，同時利用Qt跨平臺語言設計圖形交互界面，接著用這些設計好的模塊來構建一個校園導航手服務機器人的人機交互實例，并移植到目標板上，達到一個完整的嵌入式語音與圖形雙通道的交互界面。最后對整個交互系統(tǒng)進行整體測試，通過實驗結果表明，系統(tǒng)達到了預期的友好、自然的交互性的目的。
[Abstract]:With the continuous progress and rapid development of computer technology, the function of service robot is becoming more and more rich, and the interaction interface between user and service robot is also improving. As an important part of server robot system, the development of man-machine interface is becoming more and more important. Human beings need a more natural and convenient way to communicate with robots. As a special function of human, language is not only natural, but also convenient, and it is one of the most ideal human-computer interaction methods. Nowadays, the development of speech technology can be divided into two directions: one is continuous voice interaction system with large vocabulary, which is implemented on computer platform, such as voice query service system; Another important development direction is the application of portable, miniaturized voice products, such as voice control of vehicular devices, voice dialing on mobile phones, intelligent home appliances control, intelligent toys, etc. Most of these applications are implemented with special voice chips. Aiming at the development direction of miniaturization, this paper designs and implements a small vocabulary voice interactive system based on ARM embedded platform, and adds a graphical user interface to achieve a complementary interaction effect of two channels. According to the characteristics of ARM embedded system platform and the actual demand of man-machine interface, the software and hardware system of the target platform is properly tailored and the function of voice chip is optimized. It provides good man-machine interactive operation for practical application. In this paper, the embedded system and its Linux operating system are studied, then the driver and application program are designed according to the characteristics of voice chip, and the graphical interactive interface is designed by using Qt cross-platform language. Then the designed modules are used to construct a human-computer interaction example of campus navigation hand service robot, and it is transplanted to the target board to achieve a complete embedded interactive interface between voice and graphics. Finally, the whole interactive system is tested, and the experimental results show that the system achieves the desired goal of friendly and natural interaction.
