Voice Recognition

What Does Voice Recognition Mean?

Voice recognition is a technique in computing technology by which specialized software and systems are created to identify, distinguish and authenticate the voice of an individual speaker.


Voice recognition evaluates the voice biometrics of an individual, such as the frequency and flow of their voice and their natural accent.

Voice recognition is also known as speaker recognition.

Techopedia Explains Voice Recognition

Voice recognition powered systems are primarily designed to recognize the voice of the person speaking. Before being able to recognize the voice of the speaker, voice recognition techniques require some training in which the underlying system will learn the voice, accent and tone of the speaker. This is generally accomplished through a series of textual words and statements that the person has to speak through the built-in or external microphone.

Voice recognition systems are related to speech recognition systems but the former only identifies the speaker whereas the latter can understand and evaluate what has been said.
