Voice Input and Speech Recognition

• Microphones convert spoken words (analog signals) to digital signals that can be processed by a computer.  (Words are ‘digitised’)

• Digitized words are compared to  ‘voice templates’ stored in memory.

• Customizable devices can be ‘trained’ to recognize an individual’s speech.

• Current systems are still rather primitive and have limited vocabularies: however, rapid developments are ..being reported.
• If a word is recognized, it is processed: if not, then the user has to give a recognizable input.
