Speech recognition software is a technology that allows computers to understand and process human speech. It converts spoken words into text, enabling users to interact with devices using their voice. This software is commonly used in applications like virtual assistants, transcription services, and voice-controlled devices. The technology works by analyzing sound waves and matching them to known patterns of speech. It uses algorithms and machine learning to improve accuracy over time. Popular examples of speech recognition software include Google Assistant, Siri, and Amazon Alexa, which help users perform tasks hands-free.
