- W1528479110 abstract "In this paper, we describe an implementation of an intonational quality assessment system for foreign language learning using a handheld portable device. The Viterbi algorithm is employed to conduct the forced alignments that indicate the boundary of each phonemes and a pitch detector is used to extract the intonational features. The tonal pitch type of the segmented syllables is classified and the tendency of the pitch movement is measured. Then, the score of the spoken sentence is generated based on this information. We have implemented this system on an ARM7 RISC processor based system. For real time operation, we applied fixed-point arithmetic to the signal processing kernels and rearranged the algorithm flow of the system. As a result, the system runs in real time on a 60MHz CPU clock frequency." @default.
