How does Speech Recognition Work?


                  Now let us understand the four steps involved in speech recognition:
                  1.  Analyse the audio

                  2.  Break it into parts
                  3.  Digitise it into a computer-readable format

                  4.  Apply a set of instructions to match the audio with the most suitable text representation

                  Role of Artificial Intelligence in Speech Recognition


                  AI-powered  speech  recognition  technology  adds  convenience  to  its  users.  It  has  the
                  ability to recognise an individual based on their audio command. These systems use the

                  grammar structure, syntax and composition of audio and voice signals to process the
                  speech. The accuracy of conversion has almost reached 95%.

                  Almost all the smartphones currently use a virtual assistant to understand the human

                  voice and perform actions accordingly. For example, an android-based smartphone has
                  Google Assistant as virtual assistant which listens voice commands and performs action

                  like make a call, send a message, open photos, etc. Some other voice assistants, which
                  works on speech recognition technology, are Apple’s Siri, Amazon’s Alexa, Meta AI, etc.

                  Areas where AI-powered Speech Recognition is Being Used

                  Currently, speech recognition is being used for:

                     • searching information on Google.

                     • writing emails, composing documents on Google docs.

                     • carrying out household tasks, such as turning on the lights, boiling water, adjusting the
                     thermostat, etc with the help of smart devices.

                     • identifying a person’s voice and authenticate.
