34、也被體現(xiàn)在電子產(chǎn)品設(shè)計中。采用一顆語音芯片，讓產(chǎn)品開口說話，可以起到強化宣傳品牌、指導(dǎo)用戶使用、故障緊急提示、娛樂等功能，使產(chǎn)品設(shè)計新穎實用、先聲奪人、出奇制勝。</p><p>　　不同的產(chǎn)品功能設(shè)計和市場需求，在設(shè)計時必須正確選用不同的語音芯片或組件，以達(dá)到最佳的性價比。工程師可以從以下幾個方面考慮選用哪種類型的語音芯片。</p><p>　　一、語音內(nèi)容錄制到語音芯片后，內(nèi)容是否要經(jīng)

35、常修改:</p><p>　　如果語音內(nèi)容經(jīng)常要修改，例如電子留言機、錄音賀卡等產(chǎn)品設(shè)計，應(yīng)該采用ISD系列或APR系列的語音錄放電路，這兩種芯片都支持任錄任放，掉電語音內(nèi)容不會丟失，有10秒-16分鐘各種不同的芯片可供選擇。音質(zhì)較好，可接近磁帶音質(zhì)。</p><p>　　如果語音內(nèi)容寫入后就不需要修改，可考慮采用OTP型（一次性燒寫）語音電路和掩膜型語音電路。</p>&l

36、t;p>　　二、如何選擇OTP型或是MASK型語音電路:</p><p>　　這兩者中如何選用，則主要看定單的數(shù)量、品種以及交貨期。</p><p>　　OTP型語音電路需采用專用編程燒寫器將語音內(nèi)容編輯后燒入，需PC機支持。這種芯片無訂量限制，一片也可以制作，交貨快捷。外圍元件少，分段簡單，價格較低，目前有10秒/21秒/42秒/85秒/170秒/341秒等多種型號可選（均可以分多

37、段應(yīng)用）。適合需快速推出產(chǎn)品，批量較少，品種多，語音不需改動的產(chǎn)品選用。已在各種家電、摩托車、煤氣報警器、出租車計價器等產(chǎn)品上獲得廣泛的應(yīng)用。</p><p>　　如果定單數(shù)量很大（2萬片以上），要求價格很低的應(yīng)用，如各種電子玩具、電子念佛機等產(chǎn)品，則應(yīng)采用掩膜型（MASK）語音電路。目前有3秒-360秒多種規(guī)格供選擇，可分成多段。MASK芯片定貨時有一個起訂量和滿單量，如果首次投單量達(dá)不到廠家規(guī)定的滿單數(shù)量，通

38、常還需支付1500-3000美金的光罩費（一般廠家都承諾在一年內(nèi)投滿規(guī)定數(shù)量則退還光罩費）。生產(chǎn)周期較長，通常需要35-45天。投單以后，就無法更改，風(fēng)險較大。</p><p>　　三、看語音錄制的長度：</p><p>　　從上面介紹可以看到，ISD/APR單片語音錄放芯片的最長錄音時間是16分鐘（4KHZ采樣率）。在這個錄音時間內(nèi)，采用ISD/APR芯片有較好的性價比。奔流公司新推出的

39、BMP5008多段錄放板，采用全新32K采樣電路設(shè)計，音質(zhì)好，可做4-8分鐘多段錄放，且價格低，不另需單片機支持，建議采用。如果做更長時間的錄音（超過16分鐘以上），以上芯片優(yōu)勢均不明顯，建議采用奔流公司的MP3系列通用開發(fā)板和BSP-60開發(fā)板，其音質(zhì)、錄音長度、使用方便性和價格等更有優(yōu)勢，最長可做到幾十個小時的錄音。（這兩個開發(fā)板的詳細(xì)介紹見本手冊的相關(guān)文章）。</p><p>　　四、看要求的語音回放音質(zhì)：

40、</p><p>　　一般的語音回放，ISD/APR單片語音錄放電路和OTP/MASK芯片應(yīng)該都能勝任。但對于有些音質(zhì)要求特別高的場合，比如設(shè)計醫(yī)學(xué)模型心肺聽診系統(tǒng)，要求逼真回放心、肺的正常音、異常音，一般的語音芯片的音質(zhì)就達(dá)不到設(shè)計效果，應(yīng)采用MP3通用開發(fā)板。</p><p>　　五、根據(jù)產(chǎn)品設(shè)計中有沒有單片機：</p><p>　　如果有單片機的，以上介紹的芯

41、片基本上都可以采用。如果沒有，則只能在OTP芯片和ISD1810、1110、1420、2560，APR9301、9600中選擇了。ISD4000和APR6000系列的芯片都需要單片機支持。</p><p>　　ISD1110（單片多段錄放電路，10秒/6.4K采樣，可鍵控錄放，5V供電）</p><p>　　ISD1810（單片8-16秒可調(diào)單段語音錄放電路，3V供電，16腳DIP封裝）I
