What Is Voice Biometrics?

Voice biometrics technology, simply put, verifies the identity of a speaker. Somewhat confusingly, it’s also known as voice recognition, speaker recognition, voiceprinting, voice authentication and others. For the sake of clarity, we call it voice biometrics. Speech Recognition Versus Voice Biometrics Automated speech recognition (ASR) is a key aspect of technologies such as interactive voice… Read More

What Is Speech Synthesis or Text-to-Speech?

Speech synthesis, or text-to-speech (TTS), is the computer-based creation of artificial speech from normal language text. Not to be confused with recorded audio playback, TTS is computer-generated speech formed from text. How It Works There are two main components of a TTS system: The first is natural language processing (NLP), which converts raw text (including… Read More

Noise Reduction in Speech Recognition

Automated speech recognition (ASR) has to effectively distinguish spoken words from background noise in a real-world (i.e., noisy) environment. In an ideal listening environment (i.e., no background noise) such as a lab where a technician is training a new system, speech recognition systems can easily identify and convert spoken words into strings of text that… Read More

What Is Speech Recognition?

Automatic Speech Recognition (ASR) software transforms voice commands or utterances into digital information that computers can use to process human speech as input.  In a number of varying applications, speech recognition enables users to navigate a voice-user interface or interact with a computer system through spoken directives. How It Works Given the sheer number of words… Read More
