Voice recognition is a deep learning technique used to identify, distinguish, and authenticate a particular person’s voice. It evaluates an individual’s unique voice biometrics, including frequency and flow of pitch, and natural accent. Although the terms “voice recognition” and “speech recognition” are often used interchangeably, they are distinct: Speech recognition recognizes spoken words; voice recognition identifies the speaker.
Voice recognition is most often used as a security measure to confirm the identity of a speaker. Voice recognition is a contactless, software-based technology, making it one of the most convenient and readily accepted types of biometrics, and it is commonly paired with facial recognition for higher levels of security. It is increasingly utilized for user verification on mobile applications and devices, especially by chip makers focused on the Internet of Things.
