語音波包絡 的英文怎麼說
中文拼音 [yǔyīnbōbāolào]
語音波包絡
英文
envelope of the speech wave-
The main aim of speech signal processing is speech coding, speech recognition and speech understanding by automaton. in this paper, firstly, some basic signal process are discussed, such as signal filter, sampling, fft, pitch detection, then, they are tested on the testing board designed by the author
論文中首先對語音信號的基本處理問題進行了分析和對比,然後在自己設計的基於tms320vc5402的dsp實際系統上,進行了語音處理過程的濾波、采樣、傅立葉變換和譜包絡提取的演算法實現研究,討論了在演算法的dsp實現方法,分析了運行實驗結果。The quantized lp coefficients are replaced by the unquantized lp coefficients in the frequency domain expression of the feel weighted filter. the error signal has more similar envelope shape, and the hearing effect is better than before because the unquantized lp coefficients have more accuracy than quantized lp coefficients
由於未量化的線性預測系數具有更高的精度,因此,誤差信號通過修正後的感覺加權濾波器以後,具有與語音信號譜更加相似的包絡形狀,從而更好地利用共振峰對誤差的掩蔽效應,達到更佳的主觀聽覺效果。
