中文摘要 | 本文提供一種以適應性格型濾波器為基礎的特定語者國語音辨識系統之應用。傳統大多數的語言辨識系統,諸如CELP及分析一合成參數估算法,要求高品質且需維持低傳輸率4.8 Kb/Sec以下,本文提出之技術不但在壓縮上能保持高品質不失真,且在傳輸上減低錯誤率,擁有高可靠度。模擬實驗結果顯示,以20人為樣本,唸各人名字一遍,訓練後的確認正確率約為95%。 |
英文摘要 | This paper proposed Chinese Speakers verificatioon system based on adaptive RLS Lattice filters, Many traditional techniques for the coding of high quality Chinese speech below 4.8 K bits /sec. such as CELP and different class of analysis-by-synthesis adaptive predictive coders. The use of Adaptive RLS Lattice filters techniques ehnances the performance at lower rates and contribution of various coder parameters to the performance of coder. We collect the speech data from 20 persons, first segmented into small frames and then take LPC as their feature, Each of them spoken his or her anme. Finally, we use our method and apparatus as training and calling machine. After training, the results of recalling test shows that the 20's speakers dependent speech recognition can get very good performance of 95%. |
