【正文】 發(fā) 2022 年 5 月 20 日摘 要語(yǔ)音識(shí)別是一門交叉學(xué)科。近二十年來(lái)，語(yǔ)音識(shí)別技術(shù)取得顯著進(jìn)步，開(kāi)始從實(shí)驗(yàn)室走向市場(chǎng)。 語(yǔ)音識(shí)別聽(tīng)寫機(jī)在一些領(lǐng)域的應(yīng)用被美國(guó)新聞界評(píng)為 1997 年計(jì)算機(jī)發(fā)展十件大事之一。隨著語(yǔ)音技術(shù)的不斷發(fā)展進(jìn)，人們不光可以用語(yǔ)音來(lái)控制家電，聲控產(chǎn)品也越來(lái)越受人們的歡迎，成為了 21 世紀(jì)發(fā)展的一大前景。通過(guò)語(yǔ)音控制系統(tǒng)，實(shí)現(xiàn)對(duì)燈的亮度和電機(jī)轉(zhuǎn)速的調(diào)節(jié)，同時(shí)使用 1602 顯示當(dāng)前亮度等級(jí)和轉(zhuǎn)速等級(jí)。s daily life, sound control system application is no longer remote and, household appliances operating, no longer need to remote control key for various control interface, we usually say replace sb. With the mode to drive home appliance such as a variety of movements, smart appliances, people have no need for a variety of plicated operation of remote control and trouble, people can be very clear loose operating various electrical appliances products, to achieve more consistent with userfriendly interface design. Along with the speech technology unceasing development, people not only can use speech to control the household appliances, voice products are increasingly weled by the people, has bee a great prospects for development in twentyfirst Century.This graduation design research content is to study and master the SPCE061A MCU application technology, using its adaptation for digital voice recognition features, based on SCM voice light and speed regulating apparatus design. Through the voice control system, to achieve the brightness of the lamp and the motor speed regulation, the simultaneous use of 1602shows the current level of brightness level and speed.Key words: SPCE061A MCU，Speech recognition，Light modulation ，Speed control目 錄引言 .......................................................................................................................11 任務(wù)要求 .........................................................................................................1 設(shè)計(jì)任務(wù) .............................................................................................................................1 設(shè)計(jì)要求 .............................................................................................................................12 方案論證 .........................................................................................................2 方案比較 .............................................................................................................................2 方案確定 .............................................................................................................................23 系統(tǒng)框圖介紹 .................................................................................................24 硬件系統(tǒng)介紹 .................................................................................................3 凌陽(yáng) SPCE061A單片機(jī)學(xué)習(xí)開(kāi)發(fā)板 ...................................................................................3 “61 板”硬件框圖及簡(jiǎn)要說(shuō)明 .......................................................................................3 SPCE061A 單片機(jī)介紹 ...............................................................................................4 電機(jī)驅(qū)動(dòng)系統(tǒng) .....................................................................................................................5 電機(jī)電路的設(shè)計(jì) ..............................................................................................................5 電機(jī)驅(qū)動(dòng)硬件框圖及簡(jiǎn)要說(shuō)明 ......................................................................................5 LM2679 集成電路 ..........................................................................................................6 JQC16F 繼電器 .............................................................................................................8 7805 穩(wěn)壓模塊 ................................................................................................................8 LCD1602...............................................................................................................................8 LCD1602 簡(jiǎn)介 ................................................................................................................8 LCD1602 管腳功能 ........................................................................................................8 LDE燈 ..................................................................................................................................95 系統(tǒng)軟件介紹 ...............................................................................................10 初始化 ...............................................................................................................................10 ............................................................................................................................11 ............................................................................................................................14 辨識(shí)結(jié)果輸出 ...................................................................................................................16 集成開(kāi)發(fā)環(huán)境 IDE............................................................................................................176 調(diào)試測(cè)試結(jié)果 ...............................................................................................17 電機(jī)驅(qū)動(dòng)板調(diào)試 ...............................................................................................................18 軟件調(diào)試 ...........................................................................................................................197 結(jié)論 ...............................................................................................................20謝 辭 .................................................................................................................22參考文獻(xiàn) .............................................................................................................23附錄 1..................................................................................................................24附錄 2..................................................................................................................25引言近年來(lái), 消費(fèi)類電子產(chǎn)品中智能化趨勢(shì)日益明顯, 其中語(yǔ)音識(shí)別技術(shù)的應(yīng)用起到了關(guān)鍵的作用。語(yǔ)
