residual noise造句
例句與造句
- Single channel subtractive - type algorithms is often used in the speech enhancement , but musical residual noise will appear
處理寬帶噪聲最通用的技術(shù)是減譜法,但在聽覺上形成殘留“音樂噪聲” 。 - The experiment result shows that the approach restrains from the background noise and music residual noise and improved the speech - sound quality
實驗結(jié)果表明,方法有效抑制了背景噪聲和音樂噪聲并提高了語音質(zhì)量。 - 1 . speech enhancement method based on masking properties of the human auditory system is described . in this paper , a threshold is got through simulating the frequency of human auditory in order to reduce the musical residual noise and the background noise
在閾值法除噪中閾值確定是極為重要的環(huán)節(jié),本文模擬人耳聽覺掩蔽效應(yīng)來確定閾值大小,以有效的掩蔽殘留的音樂噪聲和最大限度的保留語音。 - In signal space , speech enhancement is adopted to effectively suppress the noise and increase the discriminative information embedded in noisy speech signal . however , the speech distortion introduced by enhancement , as well as the residual noise , is a very adverse factor for recognition
在信號空間,利用語音增強有效抑制噪聲,提高輸入信號中的鑒別信息,但增強帶來的語音失真和增強后的剩余噪聲是對語音識別非常不利的因素。 - In order to reduce the musical residual noise and the background noise , a speech enhancement method based on masking properties of the human auditory system is described . this method uses bark wavelet packet transform to simulate the frequency feature of human auditory model to get the threshold
本文以最大限度減少殘留噪聲和背景噪聲為目的,采用bark子波分析的方法模擬人耳基底膜的頻率分析特性來進行語音增強,重點進行模擬人耳聽覺掩蔽效應(yīng)來確定除噪閾值的研究。 - It's difficult to find residual noise in a sentence. 用residual noise造句挺難的
- It can be concluded after analysis that the speech distortion and the residual noise can be approximately regarded as multiplicative noise and additive noise , respectively . thus , we use a parallel model combination ( pmc ) algorithm , which is deployed in model space , to adapt the parameters of speech models to compensate the residual noise , or we use a cepstral mean normalization ( cmn ) algorithm in feature space to compensate both the speech distortion and the residual noise
分析表明,語音失真和剩余噪聲可近似看作乘性噪聲和加性噪聲,因此可在模型空間利用并行模型合并( pmc )算法通過調(diào)整模型參數(shù)對剩余噪聲進行補償,或者在特征空間利用倒譜均值歸一化( cmn )算法對語音失真和剩余噪聲同時進行補償。 - We analyse the dispersion of stock returns and have the tests of serial correlation . the results show that the trading mechanism has a significant effect on a number of characteristics of stock returns . first , the distribution of open - to - open returns has greater variance than that of close - to - close returns . second . the serial correlation pattern is quite different in the two return series . the open - to - open returns have negative autocorrelation coefficient , but the close - to - close returns is positive . further , employing an arma ( 1 , 1 ) model we find that in the opening . returns exhibit higher residual noise and stronger dependence on past returns , reflecting stronger deviations from the random - walk form of the market efficiency hypothesis
主要表現(xiàn)為:一,開盤收益序列比收盤收益序列具有更大的方差。二,兩種收益序列的序列相關(guān)形式不同,開盤收益序列表現(xiàn)為負相關(guān),而收盤收益序列表現(xiàn)為正相關(guān)。而且我們通過arma ( 1 , 1 )模型的進一步檢驗,發(fā)現(xiàn)開盤收益序列比收盤收益序列具有更大的殘差,更依賴于過去的收益序列,也更偏離于市場有效的隨機游走形式的假設(shè)。
