Background
The traditional voiceprint application is finished indoors at present, 1:1 comparison verification and 1: N voiceprint retrieval are carried out on a section of voice of a speaker and the existing voice in a database, however, the voiceprint technology requires a user to read dynamic texts repeatedly during registration, the operation time is slightly long, and response events are also longer; voice variability is an important reason that limits the popularity of voiceprint recognition. Physical condition, age, mood, etc. may cause a person's voice to change. Different microphones and channels have different sound processing capabilities and may also be biased in voiceprint verification. For example, when a speaker uses a device with a different type number for registration and verification, the data of the voiceprint characteristics may have slight difference after the voice is processed, and in this case, the performance of voiceprint recognition may be reduced; the environmental noise may interfere with the voiceprint recognition result. The noise may generate adverse interference to the pitch frequency, formant frequency, etc. of the speech, the degree of interference is related to the noise intensity, and when the sound in the environment is noisy and the speaker sound is relatively small, the recognition rate may be reduced. Therefore, the existing voiceprint collection is carried out in an indoor environment through professional equipment, and the requirement of portability cannot be met. The law enforcement instrument, as a law enforcement device, does not have the function of voiceprint acquisition at present and cannot complete the basic voiceprint acquisition function outdoors. At present, the number of phishing is increasing, and the public security department can only master basic sound information, so that the case can not be solved.
