Automatic speech recognition (ASR) is an independent, machine‐based process of decoding and transcribing oral speech. A typical ASR system receives acoustic input from a speaker through a microphone; analyzes it using some pattern, model, or algorithm; and produces an output, usually in the form of a text (Lai, Karat, & Yankelovich, 2008).

It is important to distinguish speech recognition from speech understanding, the latter being the process of determining the meaning of an utterance rather than its transcription. Speech recognition is also different from voice (or speaker) recognition: Whereas speech recognition refers to the ability of a machine to recognize the words and phrases that are spoken (i.e., what is being said), speaker (or voice) recognition involves the ability of a machine to recognize the person who is speaking.
