语音合成遥控指令回报系统

本文介绍了用于无人机的语音合成回报系统,代替传统的信号盘灯光显示,向地面指挥监测人员回报遥控指令接收情况。语音合成系统由基于LPC原理制成的单片语音合成处理器TMS5220组成,用Z-80 CPU实现控制。系统结构简单,通用性强,合成语音清晰、自然可懂。

A Speech Synthesis System to Report Back on Remote Control Command

In this paper a speech synthesis system is introduced, the system is used, in place of the traditional light indicator, to report back to drone ground commanders and monitors on the reception of the remote control command. The speech synthesis system is made up of TMS 5220, which is a chip LPC-based voice synthesis processor. The system is controlled by Z-80 CPU. It has the advantages of simplicity and versatility. The synthesised voice sounds clear, natural and understandable.For extracting vocal-trace parameters the covariance-lattice harmonic-mean method is used; and the LPC inverse filtering AMDF method, for extracting the pitch.
