美国德克萨斯仪器公司最近研制了一个能在一个硅片上电模拟人类声道的语言合成器.这种MOS/LSI集成电路片通过基声激励线性预测编码(LPC)获得编码语言,这是一种通过测定原始语言来分析与合成人类语言的技术,也是一种对能模拟声道的时变数字泸波器的描述.这种泸波器被周期的或随机的输入所激励.硅片上的一个8比特的数模变换器将泸波器处理的数字信息变换成合成语言.12个合成参数(10个泸波系数、基音和能量)的码子作为合成器硅片的输入;它们被存贮在一个ROM中,并由硅片电路解码,如果周期性输入就再生出来具正确基
Texas Instruments Incorporated has recently developed a speech synthesizer that can simulate a human channel on a silicon chip. This MOS / LSI chip acquires the coding language by base-acoustic excited linear predictive coding (LPC) Is a technique for analyzing and synthesizing human languages by measuring the original language and is also a description of a time-varying digital filter capable of simulating a channel, which is excited by periodic or random inputs. Silicon An 8-bit digital-to-analog converter on the chip transforms the digital information processed by the filter into a synthesized language.The code of 12 synthesized parameters (10 filters, pitch and energy) is used as input to the synthesizer silicon; Is stored in a ROM and decoded by the silicon circuit, regenerated with periodic input
