ASR (Automatic Speech Recognition)

Automatic Speech Recognition (ASR) is the computational process of converting spoken language into written text. ASR systems use acoustic models (to understand sounds), language models (to predict words), and pronunciation models (to map sounds to words). Modern ASR uses end-to-end deep learning models like Whisper, DeepSpeech, and proprietary models from Google, Apple, and Amazon. Zavi AI builds on top of ASR by adding an AI post-processing layer that transforms raw transcription into polished, professional text.
