With the increasingly widespread application of voice evidence in judicial cases, grassroots public security organs are facing practical difficulties such as a shortage of voice testing professionals and disconnect between technical capabilities and case needs. As the main battlefield for cultivating public security talents, public security colleges undertake the dual tasks of serving practical needs and leading technological innovation. In order to adapt to the new situation, face new challenges, and better cultivate students' awareness of using voice to serve cases and their ability to use voice testing methods to serve cases, public security colleges and universities invite public security practical experts, judicial appraisal experts, and technical experts in the speech recognition industry to build a set of Forensic Speech Analysis course teaching system oriented towards case needs, focusing on teaching content, teaching resources, practical teaching, teaching methods, teaching assessment system, and teacher team. This paper aims to cultivate high-quality applied voice inspection professionals who understand the profession, can apply, can innovate and have professional ethics.
