Advantages of Far-Field Automatic Speech Recognition (ASR)

Far-field speech and voice recognition is the ability to interact with smart devices using natural human language from a distance ranging from 1 to 10 m. Far-field speech recognition systems are used to recognize the user voice in a noisy environment based on speaker localization using a microphone array.
