语音的分析、合成及识别技术是人机语声通信领域中的一项重要研究课题。它作为人工智能的一个分支,在短短的几十年中得到了迅速发展。本文结合微机原理,重点介绍语音合成器S3620的特性及其开发应用。一、S3620语音合成器简介 1.S3620的特点美国AMI公司生产的S3620是适用10级线性预测编码(简称LPC)技术的单片语音合成器。其比特率极低,并采用单电源供电。语音参数数据ROM在片外,这就使得用户可根据不同应用场合制定自己的数据ROM,运用非常灵活。在硬件技术上,S3620采用先进的开关电容乘法器技术构成10级LPC格型滤波网
Voice analysis, synthesis and recognition technology is an important research topic in the field of human-computer voice communication. As a branch of artificial intelligence, it has grown rapidly in just a few decades. In this paper, the principles of microcomputer, focusing on the characteristics of S3620 voice synthesizer and its development and application. First, S3620 speech synthesizer Brief introduction 1.S3620 features AMI S3620 produced by the United States is suitable for 10 linear predictive coding (LPC) technology, single-chip voice synthesizer. Its bit rate is very low, and a single power supply. Voice parameter data ROM in the chip, which allows users to develop their own data ROM according to different applications, the use of very flexible. In hardware technology, S3620 uses advanced switch capacitor multiplier technology to form 10 LPC lattice filter network
