Problems solved by technology

[0003] However, when the user performs voice control on the smart device while the smart device is playing audio, the audio played by the smart device can be input into the smart device with the user's voice, which will affect the voice recognition function
At present, in the process of playing audio on smart devices, if you want to improve the ability of speech recognition, you can use Acoustic Echo Cancellation (AECoustic Echo Cancellation, AEC) technology to eliminate the noise generated by the smart device itself, and the AEC processing effect is the same as the sound source played by the smart device itself. The total harmonic distortion curve (Total Harmonic Distortion, THD) is related. Furthermore, the EQ (Equalizer, equalizer) curve at the speaker end of the smart device can effectively control the low-frequency components of THD, but the subsequent reduction of THD low-frequency components will affect the intelligence. The device's audio playback sound effect
[0004] Therefore, it is difficult to balance the relationship between the audio playback function and the speech recognition function in the existing technology, which reduces the audio playback effect or speech recognition efficiency of smart devices

Abstract

The embodiment of the invention discloses a device configuration method, device, device and storage medium. The method includes: determining the target equalizer parameter range according to the target use distance of the device to be configured, and the mapping relationship between the candidate use distance and the candidate equalizer parameter range; wherein, the candidate equalizer parameter range is based on the candidate equalizer parameter range Determining using the speech response rate under the distance; according to the audio playback characteristics of the device to be configured, determining the target equalizer parameter value of the device to be configured within the target equalizer parameter range. The embodiment of the present invention improves the audio playback effect of the device by evaluating the voice response rate of the smart device on the premise of satisfying the voice response rate, provides a guarantee for the sound effect of the smart device, and compares the voice response rate and the audio playback effect under internal noise The two reach the best balance point.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of smart devices, and in particular, to a device configuration method, device, device, and storage medium. Background technique [0002] With the rapid development of artificial intelligence, smart devices such as smart speakers usually have both audio playback and speech recognition functions. For example, when the smart device is playing music, the user can control the smart device by voice. [0003] However, when the user performs voice control on the smart device while the smart device is playing audio, the audio played by the smart device may affect the voice recognition function as the user's voice is input into the smart device. At present, in the process of playing audio on smart devices, if you want to improve the ability of speech recognition, you can use Acoustic Echo Cancellation (AECoustic Echo Cancellation, AEC) technology to eliminate the noise generated by the smart...
