Title: A two-level TDNN (TLTDNN) technique for large vocabulary Mandarin final recognition
Abstract: A two-level time-delay neural network (TLTDNN) technique has been developed to recognize all Mandarin finals of the entire Chinese syllables. The first level discriminates the vowel-group (a,e,i,o,u,v) and the nasal-group based on nasal ending, (-n,-ng,-others). Orthogonal combination of the two groupings in the first level enables the second level discrimination of all 35 Mandarin finals. The technique was thoroughly tested with 8 sets of 1265 isolated Hanyu pinyin syllables, with 6 sets used for training and 2 sets used for testing. The overall result shows that a high recognition rate of 95.3% for inside testing and 93.9% for outside testing is achievable.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
