最大復音數
英文
maximum polyphony-
The modulation of sound properties over a wide range of time scales is one of the most obvious characters of oscine passerine ' s vocal, whose song contains many different kinds of syllables that consist of many more multiple song phrases. in oscine passerine, ipsilateral projections of ra to nxiits innervates the ipsilateral syringeal muscles exactly, and thus they have strong ability of vocal control with variable tones, high frequency and higher lever of quality. as a result, the songs sound well
鳴禽鳴囀的最大特點之一便是其單次鳴唱時間長，鳴唱所包含的音節數量和音節種類繁多，因而由這些音節所組成的句型結構也是復雜多樣富於變化，且由於nxiits嚴格的側別控制（每一側核團只支配同側鳴肌） ，使其具有更強的控聲能力，其鳴聲音調變化幅度大，頻率高，品質因數大，音色好，因而其鳴聲也悅耳動聽。The first part of the paper is designing the testing project for grounding resistance and insulation resistance in a new way. using 16bits ad converter with programmable control amplifier replaced the way which used changing resistance to change measure range. lt is not only improved testing precision and develop the system expediently, but also reduced the area of the circuit boardwith the new way. in order to make the electric implement safety testing system have upstanding expansibility, the software and hardware of the system adopted the modularization design. adopted mcu atmegal28 as a master mcu which control mmi, realtime clock and communication with slaver mcu. atemga8 as the slaver mcu to realize testing function. so it is easy to add or reduce the testing project. the testing implement system has been developed successfully, and the comments for the system is that it has high precision, high expansibility and easy maintain. but considering the electric implement system should have intelligence and humanity abi lity. so this paper bring forward a scheme of electric equipment safety testing embedded system with speech control. after introduce the basic theory of speech recognition, the paper expatiate the characters of this system. the system is a noise conditon, not special people, small glossary, insulation word system. with these characters design the speech recognition as fellow. utilizing cross zero ratio and short energy to ensure jumping - off point and end point ; adopting mfcc as the character parameters of speech recognition ; the character parameters than be recognized by dtw. in order to ensure the credibility of this project, first realized by matlab in computer
在介紹了語音識別的基本原理后，闡述了本系統的特點：本系統是一個噪聲環境下非特定人、小詞匯量、孤立詞的語音識別系統。根據本系統的這些特點設計了如下語音識別方案：利用過零率和短時能量相結合的方式確定語音端點；採用mel頻率倒譜系數（ mfcc ）作為語音識別的特徵參數；得到的特徵參數最後通過動態時間規整（ dtw ）的模式識別方法進行識別。為了確保本系統實現方案的可靠性，首先通過計算機利用matlab軟體來模擬，在演算法模擬實現后又進一步增加環境的復雜性：加上較大的環境噪聲、突發性的噪聲等，再通過修改參數、修改參考模板、兩級識別等各種提高語音識別精度的方法來提廣東工業大學工學碩士學位論文高識別率。From computer directly, the device can get data from two specifically wav files which have double channels of data, and whose sample rate are 44100, and whose resolution are 16. then it makes digital signals convert into anolog signals and amplify them at the same time. at last, according to actual need, it can supply continuous anolog audio output of enough power and high fidelity at different speed
該設備可以直接從計算機獲取兩個雙聲道、 16位解析度、 44100hz采樣率的wav （ waveform ）聲音文件的數據，並同時將兩個聲音文件的數據進行數模轉換和信號放大，最終以能滿足實際生產需求的較高速率連續地輸出具有足夠驅動能力和高保真度的模擬信號，為終端高速磁帶復錄子機提供穩定可靠的音源。This is just a method for using to passing 16 bits 44. 1s khz passage compressing more musics within many hdcd technique, look like technique read with the strong scope of 16 bits coding. that system at used the process to inside expressed extreme of excellent technique, also reflected a personal sense of hearing, recording, electronics design with figures number coming of modern ear that handle. the graveness that hdcd technique is a figures stereo set leaps. the easy to do compares a mother for using the hdcd plait the solution code to take with a tradition of 16 mother that bits 44. 1s khz the edition take, and the hdcd can get the resolution of more detailses ; the restoring of tone color is too more accurate ; the high part is more smooth, and also little the trace of the many artificial ; more wide and dynamic scope ; big development with complicated chapter more contain clarity ; field of more wide voice ; when the musical instrument of the other and big volume give musical performance, can more goodly the hear the small volume musical instrument deeply thought to deduce. even we expect already a long time of the cd system type of the high quality way for a life time empress, 16 bits 44. 1s khz system type cd will still very longly a period of time inside can t withdrawing the music satge, because hdcd system providing first kind from the cd format obtaining bestly music
Hdcd技術是數碼音響的重大飛躍。輕易比較一個用hdcd編解碼的母帶和一個傳統的16bit 44 . 1khz版本的母帶， hdcd可以得到更多的細節解析度音色的還原也更加準確高音部分更加平滑，也少了許多人工的痕跡更寬的動態范圍大動態和復雜的章節更有透明度更寬廣的聲場當其他大音量的樂器演奏時，可以更好地聆聽小音量樂器的精微演繹。即使我們期盼已久的超高音質的cd制式面世后， 16bit 44 . 1khz制式cd仍將很長一段時間內不會退出音樂舞臺，因為hdcd系統提供了一種從cd格式里獲取最好音樂的方式。Conjugate structure algebraic code excited linear prediction was approved as itu recommendation in 1996 based on the project of usa at & t, japan ntt, franc telecom and canada sherbrooke university. cs - acelp based on adapt linear prediction is one of the most sophisticate algorithms in the field of low bit rate speech coding
共軛結構代數碼激勵線性預測語音編碼（ conjugatestructurealgebraiccodeexcitedlinearprediction簡稱cs - acelp ）演算法是1996年國際電信聯盟（ itu ）根據美國at & t 、日本ntt 、法國電信和加拿大sherbrooke大學聯合提出的方案而制定的，它是最復雜低數碼率語音壓縮演算法之一。分享友人
