在主要的工业化国家，利用人的声音作为犯罪工具的情况一直在稳步增加。在德国，多年来，在各种犯罪中，如勒索、绑架、恐怖袭击、强奸、假炸弹威胁，以及也许令人惊讶的是，在大量杀人案件中（在18个月内处理的总共538起案件中有59起），都观察到了这种趋势。因此，根据罪犯的言语行为来识别他/她已成为对我们司法系统的一个挑战。
然而，司法部门对外行人辨认说话人的可靠程度，有时对是否应考虑这种证据，有相当大的不确定性。由于这方面的研究成果不多，而且在某种程度上具有争议性，因此，保留意见当然是有道理的
In the major industrialized nations the use of the human voice as an instrument in committing crimes has been steadily increasing. In Germany, this tendency has been observed for several years in a variety of offences such as extortion, kidnapping, terrorist attack, rape, hoax bomb threats and, perhaps surprisingly, in a significant number of homicide cases (59 out of a total of 538 handled in 18 months). Thus, the identification of a criminal on the basis of his/her verbal behaviour has become a challenge to our judicial systems.
However, there is considerable uncertainty on the part of the judiciary as to the degree of reliability of speaker identification (SID) by laypersons, and sometimes as to whether or not such evidence should be considered at all. Since research findings on the subject are sparse and to some degree controversial, reservations are certainly justified
