Speech recognition

Speech recognition is a field of speech processing that aims to automatically transcribing the audio signal into text using machine learning. Sometimes, the system is also referred as Automatic Speech Recognition, or ASR in short. This technology allows users to extract text from the audio without any need of intense human labor. The text data extracted from a speech recognizer engine can also be used to further extract more useful information using Natural Language Processing (NLP) technology. This is very beneficial for some companies that contain a heavy audio data traffic like call center, movies transcription, online courses, and so forth.
