Abstract:

The rapid evolution of virtual reality (VR) technologies is transforming educational paradigms by enabling highly immersive, experiential learning across a range of professional sectors. Law enforcement, as a field requiring precise decision-making and effective communication under stress, stands to benefit substantially from these advancements. In this context, VR offers police officers the opportunity to rehearse complex, high-risk interventions within safe yet realistic environments that foster both skill acquisition and situational adaptability.

A key innovation in this area is the integration of artificial intelligence (AI)–based voice control, which further enhances the realism and interactive potential of VR training platforms. This paper presents the development, implementation, and initial evaluation of an advanced speech recognition interface designed for VR police training applications. The interface, known as the Speech Recognition System (SRS), enables trainees to control simulated scenarios and interact with virtual avatars through spoken commands, closely mirroring authentic field communication. Leveraging a real-time, offline language model and multithreaded processing architecture, the SRS is capable of accurate detection of critical phrases and keywords, supporting seamless and responsive interactions within demanding police scenarios.

The system has been deployed in training modules simulating environments such as hospitals and airports, where officers must respond dynamically to evolving situations. Trainees issue a spectrum of verbal commands—ranging from inquiry about health status to orders related to compliance and de-escalation—which are recognized and interpreted by the SRS to trigger immediate actions in the simulation. This hands-free, voice-driven approach not only reinforces operational protocols but also introduces authentic stressors, closely approximating the pressures of real-world policing.

Pilot testing involving police officers has demonstrated the system’s intuitive usability, robust recognition capabilities, and overall contribution to perceived training realism. Participants emphasized the value of the speech interface in facilitating realistic engagement and enabling more natural, scenario-based practice. The feedback has also highlighted areas for further enhancement, such as linguistic adaptation and handling of ambiguous input.

This paper provides a comprehensive overview of the technical design and deployment of the AI-driven speech recognition interface within VR police training and summarizes pilot user feedback regarding its effectiveness and impact. The results suggest that such integration of advanced voice control into VR significantly advances the efficacy and authenticity of digital simulation for law enforcement education.
