计算机术语“linear predictive coding (LPC)”的中英文意思、释义、翻译及用法-计算机英汉双解词典

术语	linear predictive coding (LPC)
释义	linear predictive coding (LPC) 线性预测编码法 A type of speech compression in which the speech production mechanism is modeled as a discrete, time-varying, linear recursive filter. This filter is further modeled by an adaptive linear predictor in a positive feedback loop. The LPC encoder then transmits voiced/unvoiced, pitch and gain signals, along with information about the linear predictor coefficients for synthesis of the speech signal at the receiving end. 一种语音压缩技术,它将语音产生的机理模型化为一个离散的、时变的、线性递归滤波器,该滤波器又进一步模型化为一个正反馈回路中的自适应线性预测器。 LPC编码器发送浊音/清音信号、音调信号、增益信号以及关于线性预测器系数的信息,用来在接收端再合成语音信号。
