Problems solved by technology
[0007] 1) For the same voiceprint recognition algorithm, the recognition rate is relatively the simplest quantitative index, which cannot reflect in which situations the algorithm performs poorly and which situations perform well, and these situations are often the shortcomings of the algorithm design , in order to more objectively reflect the advantages and disadvantages of the algorithm, it is not comprehensive to measure the recognition rate only by multiple test libraries, and the reference value is not significant;
[0008] 2) For different voiceprint recognition algorithms, there is little difference in the recognition rate of the mainstream (state of the art) algorithms. With the recognition rate as a reference standard, it is not easy to give a relatively more detailed description of the advantages, which makes the algorithm Misjudgments are prone to occur in the selection of application scenarios

Embodiment Construction
[0055] The database currently used for voiceprint recognition testing has high diversity in terms of data volume, individual characteristics, background noise, shooting equipment, etc. In the final analysis, it can be reflected in two aspects: the diversity of the target or the target itself, such as emotion , falsetto, volume, etc.; the diversity of acquisition conditions other than the target, such as background sound (noise), noise of acquisition equipment, etc., is reflected in the sound signal, that is, the signal-to-noise ratio of the voiceprint. Therefore, the purpose of this program is to make quantitative judgments on the degree of influence of different types of diversity on the algorithm, and then based on the judgment results, solve the problems that cannot be achieved by a single recognition rate:
[0056] 1) Multi-dimensional index evaluation;
[0057] 2) Problem dimension analysis and algorithm tuning feedback.
[0058] Based on the purpose of the scheme, this ...

A voiceprint recognition algorithm evaluation method based on the quality dimension, including a target-related voiceprint recognition evaluation method and a non-target-related voiceprint recognition evaluation method. For a single voiceprint recognition algorithm, multi-dimensional evaluation can be performed, The sensitivity of the algorithm to various parameters is obtained, so as to optimize the algorithm for different parameters; for different voiceprint recognition algorithms, more detailed comparison results can be provided, and the optimal recognition algorithm can be given in combination with the application environment.
Description
technical field [0001] The invention relates to the technical field of image processing. Background technique [0002] The voiceprint recognition algorithm has great reference value in the current authorized application and academic research. There are more and more voiceprint recognition algorithms proposed based on different starting points and principles, and the application range of voiceprint recognition in daily life is also increasing. Since the information of the voiceprint signal is simpler than that of images and videos, the amount of data is smaller, but the biometric features carried are sufficient for identification, so it has higher application flexibility. [0003] In terms of the quality of the voiceprint signal alone, there are relevant standards, but the standards here are mainly given for the voiceprint processing hardware to judge the signal fidelity of the device. For the voiceprint recognition algorithm, the evaluation algorithm is mainly Focus on reco...
