What process identifies and confirms the speaker's identity for secure authentication?

• A. Voice recognition
• B. Speech recognition
• C. Data
• D. Tool creation

Answer: (A)

Voice recognition identifies and confirms a speaker's identity by analyzing unique vocal traits such as pitch, timbre, cadence, and rhythm. In secure authentication, it compares a live voice sample to enrolled templates to verify who is speaking or to identify the speaker among registered users. This directly addresses the task of confirming identity from the voice, which is why it fits best. Speech recognition, by contrast, aims to convert spoken language into text, not to verify identity. The other options, data and tool creation, aren’t about authenticating a speaker at all.
