The voiceprint recorded by the police station can be used as evidence (or clue), which is very important. However, if there is no other general information such as identity information or physical characteristics, it is difficult for the public security organs to detect the case, and the parties need to wait patiently.
At present, there is no human voice information database in China and even in the world, because without voice database information and other basic information, it is impossible to compare and recognize voices from the technical level. Therefore, the simple recording can only be used as an important evidence clue and provided to the public security organ for filing a case, which is conducive to the public security organ to detect the case. In the process of handling other or similar cases, the public security organs are likely to receive unexpected gains.
