Speech recognition

Speech recognition is the technology that converts spoken words into text or computer commands.

How It Works

• Audio Input: A microphone captures sound waves and turns them into digital signals.
• Signal Processing: The system removes background noise and boosts clarity.
• Feature Extraction: Software breaks the audio down into basic sound units called phonemes.
• Acoustic & Language Modeling: AI models match sounds to words using grammar and context.
• Output: The system generates the final text or executes a spoken command.

Common Uses

• Virtual Assistants: Tools like Siri, Alexa, and Google Assistant respond to voice cues.
• Transcription: Software turns meetings, lectures, and medical notes into written documents.
• Accessibility: Hands-free controls help people with physical limitations use devices.
