【正文】 括的講：一塊芯片就成了一臺(tái)計(jì)算機(jī)。它的體積小、質(zhì)量輕、價(jià)格便宜、為學(xué)習(xí)、應(yīng)用和開發(fā)提供了便利條件。同時(shí)，學(xué)習(xí)使用單片機(jī)了解計(jì)算機(jī)原理與結(jié)構(gòu)的最佳選擇。 目前單片機(jī)滲透到我們生活的各個(gè)領(lǐng)域，幾乎很難找到哪個(gè)領(lǐng)域沒有單片機(jī)的蹤跡。導(dǎo)航裝置，飛機(jī)上各種儀表的控制，計(jì)算機(jī)的網(wǎng)絡(luò)通訊與數(shù)據(jù)傳輸，工業(yè)自動(dòng)化過程的實(shí)時(shí)控制和數(shù)據(jù)處理，廣泛使用的各種智能 IC 卡，民用豪華轎車的安全保障系統(tǒng)，錄像機(jī)、攝像機(jī)、全自動(dòng)洗衣機(jī)的控制，以及程控玩具、電子寵物等等，這些都離不開單片機(jī)。更不用說自動(dòng)控制領(lǐng)域的機(jī)器人、智能儀表、醫(yī)療器械了。因此，單片機(jī)的學(xué)習(xí)、開發(fā)與應(yīng)用將造就一批計(jì)算機(jī)應(yīng)用與智能化控制的科學(xué)家、工程師。隨著單片機(jī)的廣泛應(yīng)用，將大大促進(jìn)各領(lǐng)域的技術(shù)更新，向自動(dòng)化、小型化、智能化方向邁進(jìn)。而對(duì)于我們來說，我們這代人的目標(biāo)和任務(wù)是把這些高科技產(chǎn)品更升一個(gè)層次。畢業(yè)設(shè)計(jì)是培養(yǎng)學(xué)生綜合運(yùn)用所學(xué)知識(shí),發(fā)現(xiàn),提出,分析和解決實(shí)際問題,鍛煉實(shí)踐能力的重要環(huán)節(jié),是對(duì)學(xué)生實(shí)際工作能力的具體訓(xùn)練和考察過程，隨著科學(xué)技術(shù)發(fā)展的日新日異，單片機(jī)已經(jīng)成為當(dāng)今計(jì)算機(jī)應(yīng)用中空前活躍的領(lǐng)域， 在生活中可以說得是無處不在。因此作為二十一世紀(jì)的大學(xué)來說掌握單片機(jī)的開發(fā)技術(shù)是十分重要的。通過這次畢業(yè)設(shè)計(jì)，無論從選題到定稿，從理論到實(shí)踐都使我學(xué)到了很多東西，它不僅可以鞏固了以前所學(xué)過的知識(shí)，而且學(xué)到了很多在書本上所沒有學(xué)到過的知識(shí)。同時(shí)也明白了理論與實(shí)踐相結(jié)合的重要性，只有理論知識(shí)是遠(yuǎn)遠(yuǎn)不夠的，只有把所學(xué)的理論知識(shí)與實(shí)踐相結(jié)合起來，從理論中得出結(jié)論，才能真正為社會(huì)服務(wù)，從而提高自己的實(shí)際動(dòng)手能力和獨(dú)立思考的能力。 致 謝 在本論文完成之際，首先要向我的指導(dǎo)老師生芳致以誠摯的謝意。在論文的寫作過程中，生老師給了我許許多多的幫助和關(guān)懷。生老師學(xué)識(shí)淵博、治學(xué)嚴(yán)謹(jǐn)，待人平易近人，在生老師的悉心指導(dǎo)中，我不僅學(xué)到了扎實(shí)的專業(yè)知識(shí)，也在怎樣處人處事等方面收益很多；在此我謹(jǐn)向生老師表示衷心的感謝和深深的敬意。同時(shí)也感謝電子073全班同學(xué)的幫助和勉勵(lì)，同窗之誼和手足之情，我將永生難忘此外，我要感謝我們學(xué)院給我們提供實(shí)驗(yàn)設(shè)備的各位老師，正是由于他們的傳道、授業(yè)、解惑，讓我學(xué)到了專業(yè)知識(shí)，并從他們身上學(xué)到了如何求知治學(xué)、如何為人處事。 作者：2022年6月15日參考文獻(xiàn)[1] 張紹高.《 數(shù)字音頻技術(shù)原理及應(yīng)用》.[M]第 1 :國防工業(yè)出版社，[2] 張偉雄.《OSP 芯片的原理與開發(fā)應(yīng)用》 .第 l 版.[M] 北京:電子工業(yè)出版社，[3]『美』Ken .《數(shù)字音頻原理及應(yīng)用 》.[M].第 4 :電子工業(yè)出版社，2022,2[4] 李蘭友 ,韓其睿,江忠.《數(shù)字信號(hào)處理單片機(jī)及其應(yīng)用》.[M] 第 1 :電子工業(yè)出版社，[5] 潘琢金.《 C8051FO20 混合信號(hào) ISP FLASH 微控制器數(shù)據(jù)手冊(cè)》[J ][6] 《K9F56XXXOB Flash Memory 使用手冊(cè)》.[J][7] 鐘玉琢等.《多媒體計(jì)算機(jī)技術(shù)基礎(chǔ)及應(yīng)用》.[M]第 1 :高等教育出版社，[8] 余祖俊等.《微機(jī)檢測(cè)與控制應(yīng)用系統(tǒng)設(shè)計(jì)》.[M]第 1 :北方交通大學(xué)出版社，[9] 鐘玉琢，洗偉銼，沈洪編著.《多媒體技術(shù)基礎(chǔ)及應(yīng)用》.[M]北京:清華大學(xué)出版社 2022 年[10] 薛鈞義張彥斌等編著.《凌陽 16 位單片機(jī)原理及應(yīng)用》.[M]北京:北京航空航天大學(xué)出社 2022 年[11] 譚浩強(qiáng)編著 .《c 程序設(shè)計(jì)》.[J]北京:清華大學(xué)出版社 1999 年[12] 夏寬理編著 .《c 語言與 c 程序設(shè)計(jì)》.[J]上海:復(fù)旦大學(xué)出版社 1994 年[13] 竇振中編著.《單片機(jī)外圍器件實(shí)用手冊(cè)一存儲(chǔ)器分冊(cè)》.[J]北京:北京航空航天大學(xué)出版社 1998 年[14] 周航慈編著.《單片機(jī)應(yīng)用程序設(shè)計(jì)技術(shù)》.[J]北京:北京航空航天大學(xué)出版社2022 年[15] Arnold Berge.《嵌入式系統(tǒng)設(shè)計(jì)》.[[J]]北京: 電子工業(yè)出版社 2022 年[16] Omar ., HasegawaJohnson M., Levinson S., Gaussian mixture models of phoic boundaries for speech recognition, Automatic Speech Recognition and Understanding, 2022.

AT89C52 this single chip digital voice chip ISD2560 and recording time up to 60S design a set of intelligent voice recording system, enabling segmentation admission, bo playback voice, by software modifications can bring the whole paragraphs admissions, looping, and without the use of specialized development of ISD speech device. Digital voice recording refers to the use of digital technology on speech signal for collection, processing, and to a certain storage device for storage, and can be output as needed. Relative to the analog devices, digital equipment, ease of integration and miniaturization, lowcost, at the same time more stable, more direct, easy to operate and allows digital voice recording systems now are widely used in various areas. For example speech acquisition system used in the monitoring environment。 again in a home or school use of speech repetition machine, can be seen as a typical application of digital voice recording system. However most digital voice recording system, simple collection, storage, and playback of voice only。 although can be more of that voice fidelity, but too much of a voice data will cause demand for mass storage devices. For larger systems, through the use of largecapacity hard drives, or even large disk arrays to solve。 however for small devices, such as a portable voice Repeater, due to limited capacity, you cannot use the same method. In recent years, rapid study on speech signal processing technology, for the development of digital voice recording systems provides a new space. Speech waveform coding of data acquisition, process from the previous simple converted parameter encoding, pression, thereby greatly reducing the stored data. For example, original voice General are is used 8KHz sampling, 16bits of linear PCM coding for collection, in General of system in the on directly will collection Hou of data for storage。 and if used parameter coding on collection Hou of data for pression, save reserves is can greatly reduced, dang need recovery voice Shi, can using coding Hou of parameter for synthesis, can are quality was satisfaction single tablets machine is means a integrated in a chip Shang of full puter systems. Although his integrate most functionality on a small chip, but it has a full puter most of the parts required: CPU, memory, internal and external bus system
