Embodiment Construction
[0024] In order to make the above-mentioned purpose, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] The core idea of the present invention is to provide a method for checking cheating in satisfaction surveys based on voiceprint recognition technology, including: voice preprocessing, used to process the recording files during the satisfaction survey to obtain voices that are easy for the system to recognize File; rough selection of voiceprint recognition, which is the core of this system, uses feature extraction, modeling, pattern matching, gender judgment, score threshold and other conditions to screen out whether there is a voice similar to the reference voice in the voiceprint model library; recognition Confirmation and verification of the results. In order to improve the accuracy of the verification, the sim...

The invention relates to voiceprint recognition, in particular to a satisfaction survey cheating screening method based on a voiceprint recognition technology. The method comprises the steps that voice files are preprocessed; a model is established, a standard voice corresponding model is matched with all models in a voiceprint base, the first N voice files which have the highest matching grades and the grades are recorded, and then gender judging is carried out; the N voice files are screened according to an experience threshold value and a gender condition, a voice record which is consistent with the standard voice and has the matching grades larger than the threshold value is obtained, then the voice record and the standard voice are extracted to be confirmed with another different voiceprint recognition method, whether the matching grades are larger than the threshold value, and if yes, reserving is carried out; if no, removing is carried out, a similar group after confirming and inspecting is used as a final similar group to be submitted, an inspecting authentication report is generated as final screening results, a standard voice name, a dealer of the voice, voice similar to the standard voice, a dealer of the voice, similarity degree grades and the like can be given in the report, and if the similar group does not exist, cheating does not exist.
Description
technical field [0001] The invention relates to voiceprint recognition, in particular to a method for checking cheating in satisfaction surveys based on voiceprint recognition technology. Background technique [0002] To understand the quality of products and the service quality of dealers, it is necessary to collect statistics on user satisfaction with product and service quality. One of the tasks of manufacturers in channel management is to conduct customer satisfaction surveys for dealer services. The results of the assessment will be directly related to the interests of the dealers, because the manufacturers will refer to the assessment scores to determine the rebates of the dealers.
