Embodiment 1

[0036] like figure 1 and figure 2 As mentioned above, the wearable recording terminal 1 based on the microphone array 12 provided in the first embodiment includes a control board 11 , a microphone array 12 and a memory 13 , and both the microphone array 12 and the memory 13 are electrically connected to the control board 11 . The microphone array 12 collects multi-channel audio and voice signals, and transmits them to the control board 11, and the control board 11 stores the multi-channel audio and voice signals in the memory 13 to realize local storage. The microphone array 12 includes a plurality of microphones. By reasonably selecting the microphone type and array size of the microphone array 12, the microphone array 12 has the characteristics of small size, low power consumption, no radiation, and no foreign body sensation during carrying. Further, the wearable recording terminal 1 also includes a carrier 14 , and the control board 11 , the microphone array 12 and the me...

Embodiment 2

[0038] The cloud language ability evaluation system provided in the second embodiment includes the above-mentioned wearable recording terminal 1 based on the microphone array 12, the smart terminal 4 and the server end 5, and the wearable recording terminal 1 connects the Collect multi-channel audio and voice signals and upload them to the adjacent smart terminal 4, and the smart terminal 4 sends the multi-channel audio and voice signals to the server 5 in a forwarded manner, through the intelligent voice processing module 2 and the language ability evaluation module of the server 5 3 After performing front-end signal optimization processing and language ability evaluation, the data corresponding to the comprehensive evaluation result is sent to the smart terminal 4, and finally the comprehensive evaluation result is visually displayed through the display device of the smart terminal 4. Preferably, the smart terminal 4 is configured as one or more of terminal devices such as a ...

Abstract

The invention discloses a cloud language ability evaluation system, and belongs to the field of language evaluation. The cloud language ability evaluation system comprises a wearable recording terminal provided with a microphone array, an intelligent voice processing module and a language ability evaluation module, and the microphone array generates an audio vector file; the intelligent voice processing module firstly performs front-end signal optimization processing on the audio vector file, and then extracts multi-dimensional identification data from the audio vector file subjected to the front-end signal optimization processing by using a voice analysis algorithm corresponding to each sub-module; and the language ability evaluation module analyzes and counts the multi-dimensional identification data, and outputs a comprehensive evaluation result of the target speaker for visual display. According to the cloud language ability evaluation system provided by the invention, positioning and accurate pickup are carried out based on the microphone array, the intelligent, objective and automatic ability of the evaluation system is greatly enhanced, and the technical barrier of the existing domestic and overseas language evaluation systems is effectively broken through.

Description

technical field [0001] The present invention relates to the field of language evaluation, in particular to a cloud-based language ability evaluation system and a wearable recording terminal used in the evaluation system. Background technique [0002] According to relevant research on child development, early childhood language ability is positively related to its adult learning and academic level, because the evaluation of early childhood language ability is very important for later child development. In order to conduct effective research on children's language development, our country often adopts the method of accompanying and communicating in specific scenarios and recording multiple samples during children's growth stages. The randomness of accompanying and communicating is relatively large, and some children are afraid of adults. The objectivity of the evaluation data needs to be verified, and it is extremely difficult and time-consuming to record multiple samples at t...
