Design Of Voiceprint Recognition And Speech Recognition Based On Android

With the widespread use of computer applications,especially with the rapid development of the Android platform,a variety of Android applications show explosive growth.The security of the user's privacy data in the application is greatly threatened.While the operation of mobile devices is becoming more and more complex.It is becoming increasingly important to find a simple,secure method for identifying and simplifying application operations.At the same time language is the most convenient and effective communication between people,and is the most direct way to communicate with the machine,so the design of voiceprint recognition and voice recognition system on android platform to protect user privacy and user operation has great practical significance.In this paper,the principle of voiceprint recognition and speech recognition is analyzed,including the method of extracting the characteristic parameters of speech and the method of pattern matching,and puts forward the shortcomings of these methods.Secondly,it introduces the specific scheme of voiceprint recognition and speech recognition in detail.Then,the realization of Android-based voiceprint recognition and voice recognition system is designed.Finally,build a test platform to evaluate the system performance.In this paper,an improved Shazam algorithm is proposed and applied to the voiceprint recognition system,which combines the voiceprint recognition function and the speech recognition function to form an integrated system.The system to a certain extent,improve the application of mobile devices in the security and operability.Tests sho w that the correct rate of voiceprint recognition is not less than 90%.In the case of the existing mature science and technology,the recognition rate of the whole system can reach not less than 85%.The research results of this paper have important reference significance to the application of safety and convenient operation.
