Based on the Mandarin pronunciation recognition technology, by the frequency selected from Mandarin speech input cavity resonance curve defined by the pickup, the Chinese word, vowel and consonant Pinyin word sequence can be identified. Combination of Chinese speech consonants, vowels and tones forms Chinese Pinyin sentence sequence. By the syllable by syllable analysis method, the frequency domain analysis technique of amplitude frequency does not need to learn or train for a particular persons voice, words and sentences. The adaptive DFT ( Discrete Fourier Transform) spectral analysis algorithm only occupies a very small amount of calculation. The method can determine the four tones of Mandarin, have fast response speed, small storage space, and can easilybe embedded to other devices. [ABSTRACT FROM AUTHOR]

It is an urgent need to improve the innovation ability of college students in the modern society, and robot practice platform is the best engineering project. Therefore, the course design of MCU takes "robots control with speaker-independent voice"as subject. The students work in group and design the experiment by themselves to go through the prescribed and alternative experiment modules. Purpose is to achieve the robots control with voice in the engineering practice. It is the optimal combination of teaching and scientific research, and matches the idea of teaching innovation. The practice of a group is taken as the example, it is proved that this innovative course design of "robots control with speaker-independent voice " can lay a solid foundation of the theoretical knowledge and enhance the students' practical ability, and can also lay the experimental foundation for innovation practice platform of robots in college.
