摘要
为避免音响系统受环境噪音和人为因素的影响使输出端的音量幅度波动过大,项目提出了一种全向人声自动增益控制扩音系统,利用人声辨识算法来收音,运用自适应滤波技术进行人声分离并通过自动增益控制电路实现恒定功率输出,确保输出音量幅度恒定。
In order to avoid the influence of environmental noise and human factors on the sound system,which makes the output volume amplitude fluctuate too much,the project proposes an omnidirectional human voice automatic gain control amplifying system,which uses human voice identification algorithm to receive sound,uses adaptive filtering technology to separate human voice,and realizes constant power output through automatic gain control circuit to ensure constant output volume amplitude.
