一、引言自1978年美国德州仪器公司推出第一个LSI语音合成处理芯片以来,语音合成技术取得了很大进展,各种LSI语音合成芯片相继出现,语音合成技术在许多方面已得到了实际应用。本文介绍一个自动语音报时系统。该报时系统以APPLE-Ⅱ微型计算机内的6502CPU作为主处理机,通过6522多用途接口芯片与TMS5220声音合成处理器相连接,其语音输出经滤波、放大后可直接推动小型扬声器。合成器的词汇表是在同一部APPLE机上对汉语普通话单词语音进行短时分析所得。报时程序和词汇表共占内存不超过2K字节。
I. INTRODUCTION Since the first LSI speech synthesis processing chip was introduced by Texas Instruments in 1978, great progress has been made in speech synthesis technology. Various LSI speech synthesis chips have appeared one after another, and speech synthesis technology has been applied in many aspects . This article describes an automatic voice timekeeping system. The timing system to APPLE-Ⅱ microcomputer 6502CPU as the main processor, through the 6522 multi-purpose interface chip and TMS5220 voice synthesis processor is connected to the voice output is filtered, amplified directly to promote small speakers. The synthesizer’s vocabulary is a short-term analysis of Chinese Mandarin word speech on the same APPLE machine. Timekeeping procedures and vocabularies together occupy less than 2K bytes of memory.
