Speech Recognition

In computer science and information technology, Speech Recognition is the act of receiving a speaker's voice as audio input within a specific program, and subsequently rendering that input into a machine understandable format within a given software program, system or platform.

Speech Recognition can be best characterized as "knowing or deducing what the speaker has said".
