Abstract: Abstract A voice authentication system is disclosed for use in a secure digital access control environment using voice as an authentication factor. The system comprises a processor, memory, a communication interface, an input acquisition module, a preprocessing module, an analysis engine, and an output control module. The communication interface receives voice samples, microphone audio streams, enrollment voiceprints, liveness indicators, and access request metadata. The preprocessing module validates and normalizes received input records before the analysis engine performs voice authentication using stored rules, profiles, policies, model parameters, or reference records. The output control module compares a generated decision value with a stored threshold or policy condition and generates voice authentication results, liveness rejection alerts, access approvals or denials, and audit records. The system stores an audit record linking source identity, validation state, decision value, and selected output action. The arrangement provides a controlled technical data path from input capture to Fig. 1 Dated June 23, 2026 / Mungalpara Jigneshbhai Chhaganbhai IN/PA-2640 Agent for the Applicant
