Abstract: A wake-up test device for intelligent voice equipment is taught herein. The wake-up test device includes a fixed frame. The wake-up test device further includes a first clamping assembly arranged on the fixed frame. The wake-up test device further includes a second clamping assembly arranged on the fixed frame. The first clamping assembly and the second clamping assembly can be brought to be close to or far away from each other. The wake-up test device further includes a vibration exciter arranged on the first clamping assembly or the second clamping assembly. An object to be tested is placed on the vibration exciter, the first clamping assembly and the second clamping assembly are brought to be close to each other and fix the object to be tested on the vibration exciter, so that the object to be tested attaches to the vibration exciter.

Abstract: An audio signal processing method including the following steps: acquiring a bone conduction audio signal collected by a bone conduction vibration pickup device; acquiring a low frequency transfer function which matches the bone conduction audio signal and a high frequency transfer function corresponding to the low frequency transfer function, wherein the low frequency transfer function and the high frequency transfer function are corresponding transfer functions between the bone conduction audio signal and an air conduction audio signal which correspond to the same voice; and performing frequency domain extension on the bone conduction audio signal on the basis of the low frequency transfer function and the high frequency transfer function, and taking the extended initial audio as output audio. The effect of improving the integrity pf a voice signal collected by a terminal device is achieved.
