Far-field pickup performance evaluation method and system, electronic equipment

Abstract

The invention discloses a far-field pickup performance evaluation method, a far-field pickup performance evaluation system and an electronic device. The electronic device uniformly calls a plurality of voice recognition engines for carrying out voice recognition on audio files which are respectively subjected to voice pickup by a pickup device, so that the recognition accuracy rates corresponding to the plurality of voice recognition engines are obtained, further, the pickup performance of the pickup device is evaluated according to the plurality of recognition accuracy rates of the audio files, and therefore, the system provided by the invention can be used for carrying out objective and correct testing evaluation on the pickup performance of the pickup device for sound pickup in the far-field pickup system.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a far-field sound pickup performance evaluation method and system, and electronic equipment. Background technique [0002] Usually, evaluating the quality of a far-field miking result mainly depends on the miking effect collected by the miking system. At present, the evaluation of sound pickup effect is divided into two ways: subjective evaluation and objective evaluation. [0003] Among them, in the subjective evaluation method, by playing a clean undistorted voice signal, after being picked up by the pickup system, let a group of people listen to it at the receiving end, and then give a score of 1-5 points for the pickup effect , the average score of all the test personnel is used as the final sound pickup effect score. The disadvantages of using this method are: time-consuming, laborious, and high requirements for the test personnel. [0004] Commonly used objectiv...

[0003] Among them, in the subjective evaluation method, by playing a clean undistorted voice signal, after being picked up by the pickup system, let a group of people listen to it at the receiving end, and then give a score of 1-5 points for the pickup effect , the average score of all subjects, as the final sound pickup effect score, the disadvantages of this method are: time-consuming, laborious, and high requirements for the subjects

These objective evaluation test methods and test instruments are all applied to the measurement of the end-to-end communication pickup effect. The tester uses the analog telephone interface to test the pickup effect between the end-to-end gateways. The disadvantage is that it can only be applied to A voice system or device with an electrical interface (such as a gateway, or an analog audio interface), which cannot be applied to the correct test and evaluation of the far-field sound pickup effect, nor can it be used for sound pickup in the far-field sound pickup system. Accurately test and evaluate sound performance
