摘　　要：英语翻译机在国际交流、合作中扮演着至关重要的角色,辅助扩音装置容易受到干扰噪声的影响,致使扩音效果较差,提出英语翻译机辅助扩音装置优化研究。硬件优化单元包括单片机重选单元、语音芯片优化单元与辅助扩音电路优化单元;软件优化模块包括干扰探测模块、噪声信号消除模块与语气语音合成模型优化模块。实验数据显示:优化后辅助扩音装置信噪比SNR、扩音响度与3 dB带宽均得到了提升,充分证实了辅助扩音装置优化效果较好。English translator plays an important role in international communication and cooperation. The auxiliary public address device is easy to be affected by interference noise, resulting in poor public address effect. The optimization research of auxiliary public address device of English translator is proposed. The hardware optimization unit includes single chip microcomputer reselection unit, voice chip optimization unit and auxiliary amplifying circuit optimization unit;The software optimization module includes interference detection module, noise signal elimination module and tone speech synthesis model optimization module. The experimental data show that the SNR, loudness and 3 dB bandwidth of the auxiliary public address device are improved after optimization, which fully proves that the optimization effect of the auxiliary public address device is good.
