Artificial intelligence is the intelligence of machines or software and is a branch of computer science that studies and develops intelligent machines and software. The study and design of intelligent agents is where an intelligent agent is a system that sees its environment and takes actions that maximize its chances of success. Speech recognition is a part of computer science. It is also known as computer speech recognition, automatic speech recognition, and speech to text. The training is where an individual speaker reads sections of text into the system. The systems use the person’s voice to fine tune it. The recognition of that person’s speech leads to more accurate transcription. Speaker Independent systems are systems that do not use training. Speaker dependent systems are systems that use training.
