Speech Recognition

Automatic Speech Recognition (ASR) converts spoken human language into written text: it is the core engine for hands-free computing.

ASR systems leverage advanced AI and machine learning (ML) models to analyze acoustic data, separating speech from noise and transcribing phonemes into words. This technology powers ubiquitous virtual assistants (e.g., Apple's Siri, Amazon's Alexa) and enables critical real-time applications: medical dictation, courtroom transcription, and contact center automation. Accuracy has dramatically improved: modern systems handle diverse accents, dialects, and complex vocabulary with high precision (often exceeding 95% word accuracy).
