Branches of AI
Speech RecognitionThe process of enabling a computer to identify
and respond to the sounds
produced in human speech.
What does it do??• •Verbal human – machine interaction• •Response from computer in natural language• •User reliability• •Simplified tasks
Types of ASR
• •Text-independent identification • • Text-independent verification• • Text-dependent identification• • Text-dependent verification
Types of speech recognition system
••Speaker dependent••Speaker independent••Speaker adaptive
How does it work??!!
Advantages • •Menial computer tasks• •Assists paralysed people• •Comfortable human-machine interaction • •Saves time for user• •Simple handling of software
Applications
