摘要: 簡要討論了嵌入式文語轉(zhuǎn)換(ETTS)系統(tǒng)的概念.介紹了一個基于DSP實時實現(xiàn)的嵌入式漢語文語轉(zhuǎn)換(ECTTS)系統(tǒng).基于DSP實現(xiàn)的結(jié)果,分析了ECTTS系統(tǒng)的VLSI實現(xiàn)方案,提出了基于動態(tài)內(nèi)存管理的ECTTS系統(tǒng)前端處理VLSI實現(xiàn)方案,基于解碼語音幀的ECTTS系統(tǒng)后端合成VLSI實現(xiàn)框架并對ECTTS系統(tǒng)的VLSI實現(xiàn)中的存儲器及總線結(jié)構(gòu)進(jìn)行了討論.

Abstract: The concept of Embedded Text-To-Speech (ETTS) system is first discussed. Then a real time realized Embedded Chinese Text-To-Speech (ECTTS) system based on DSP is introduced. Based on the DSP realization results, the VLSI design scheme of the ECTTS system is discussed. For the ECTTS system front-end processing, a VLSI design scheme based on the dynamic memory management is suggested. For the ECTTS system post-end processing, a VLSI design architecture based on the decoded speech frame is also proposed. The memory and the bus structure of the VLSI design of ECTTS system are discussed. -
