The project team made a detailed research report, technical report and video demonstration to the appraisal committee, and reported the latest results and its application in the fields of finance, social security, automobile, etc. Finally, they made the economic and social benefits analysis from the direct and indirect, and the expected economic benefits. Subsequently, the test team announced the pre-test opinions and the name list of test groups, and the project team reported the preliminary testing work, then accepted that the results of the acceptance test were basically consistent with the test results in the report--- the system has strong noisy robustness and self-learning ability.

After questioning and discussion by the expert group, the appraisal committee unanimously decided that the result satisfied the demand of technologies and applications of identity authentication based on voiceprint in the case of being unsupervised and reached the international leading level. In view of the security in protecting users’ identity authentication of the results with low cost, high accuracy and weak privacy, the Committee recommends that the application be promoted in all fields as soon as possible.

The “dynamic security code speech based unsupervised identity authentication system " was jointly achieved by Speech and Language Technology R&D Center and Beijing d-Ear Technologies Co., Ltd.. Under unsupervised circumstance in cyberspace, the achievement utilized the speech signal’s characteristic of ‘simple in form, rich in information’, integrated voiceprint recognition, speech recognition, emotion recognition, anti-recording detection, etc., presented dynamic security code speech based unsupervised identity authentication technology scheme, and accurately implemented unsupervised identity authentication, providing new technologies and applications of Internet, networking and big data as well as security protection for people’s daily life. The products using the key technologies of this achievement have been applied in the fields of finance, social security, medical insurance and security, which have brought about great economic and social benefits, and are typical cases of artificial intelligence application. It is of great significance for the construction of smart city and the development of social economy.
