Dynamic device speaker tuning for echo control

Dynamic device speaker tuning for echo control includes detecting audio rendering from a speaker on a device; based at least on detecting the audio rendering, capturing, with a microphone on the device, an echo of the rendered audio; performing a Fourier Transform on the echo and the rendered audio; determining a real-time transfer function for at least one signature band; determining a difference between the real-time transfer function and a reference transfer function; and tuning the speaker for audio rendering, based at least on the difference between the real-time transfer function and the reference transfer function, by adjusting an audio amplifier equalization. For some examples, the signature band represents a wall echo or an alternative mounting option. For some examples, the echo is collected during intervals while the audio rendering is ongoing. 用于回声控制的动态设备扬声器调谐包括：检测来自设备上的扬声器的音频渲染；至少基于检测到该音频渲染，利用该设备上的话筒来捕捉经渲染音频的回声；对该回声和经渲染音频执行傅里叶变换；确定针对至少一个签名频带的实时传递函数；确定该实时传递函数与参考传递函数之间的差异；以及至少基于该实时传递函数与该参考传递函数之间的差异
