A reciprocating compressor using labyrinth seal ( labyrinth piston compressor , lpc ) can compress and transport gases in an oil - free way . it has many advantages , such as non - lubricated maintenance , no friction loss , no hot spots , minimal wear and tear , and so on 采用迷宫密封的往复式压缩机可以完成洁净气体的压缩和输送,具有压缩过程无润滑、无接触摩擦、气体无污染、安全可靠等优点。
I achieve approximately the increment of sound level in sound focusing region relative to sound incidence ( ? lpc ) , and make ascertain the sound pressure level in focusing region accurately . through draw the curve of wrap - up line equation with matlab program of computer software 文章最后总结出本文理论分析所得的几个解析式和避免声聚焦的设计原则,同时在理论和实验上提出今后研究其它构造时的一些方法和方向。
By using the lpc coefficients of noise to predict all the speech signal , the method gets the lpc prediction error lpcpe sequence . then use it to substitute the speech sequence to detect the speech terminal extract the speech features and to recognize in a suitable way 该方法利用噪声的lpc系数去预测语音信号,从而得到lpc预测序列,然后把它代替原语音序列来进行语音端点的检测语音特征的提取和在合适的匹配方式下的识别。
Although there still exist many problems which need to be overcome such as the technique of large - vocabulary , speaker - independent , continuous speech recognition , the technique ( lpc and dtw ) for small - vocabulary , speaker - dependent , isolated - word speech recognition has come to the age of maturity 虽然大字表非特定人连续语音识别技术仍有许多难点尚未解决,但特定人小字表孤立词语音识别技术( lpc和dtw算法)已相对成熟。
The demand is the power forcing speech coding to progress . traditionally linear prediction ( lpc ) vocoders are very efficient , which can encode speech from 800 to 2400bps , but unfortunately , artifacts such as buzzes , thump , and tonal noise always exist in them 经典的线性预测( lpc )声码器具有很高的编码效率,可以极低的码率( 800 2400bps )对语音信号进行编码,不幸的是它的合成语音听起来很不自然,常常夹杂着嗡嗡声,重击声或者音调噪声。
