Voice assistants are increasingly being integrated into healthcare environments for data entry, enhancing efficiency and accessibility for healthcare providers. However, using these systems raises critical security and privacy concerns due to the sensitive nature of health data and the unique vulnerabilities of voice-enabled technologies. This paper examines the security and privacy implications of using voice assistants for data entry in healthcare settings, exploring risks associated with data interception, unauthorized access, and inadvertent information leakage. We analyze how voice assistant systems process, store, and transmit data, identifying potential attack vectors and privacy vulnerabilities. The paper also reviews existing regulations and standards, such as HIPAA, that impact the deployment of voice-enabled systems in healthcare. To address these challenges, we propose a framework for secure voice data entry, incorporating multi-layered authentication, encryption, and real-time anomaly detection. Our findings underscore the need for healthcare providers to adopt robust security protocols and privacy practices to ensure compliance and protect patient confidentiality. This research contributes to a growing body of knowledge aimed at the safe and ethical integration of voice assistants in healthcare, providing guidelines for technology developers and healthcare administrators.
