Speech Recognition

Speech recognition is the technology by which AI analyzes human speech and converts it into corresponding text data. Also known as automatic speech recognition (ASR) or speech-to-text, it combines natural language processing with acoustic processing to achieve sophisticated understanding of spoken language. While earlier systems struggled with noise and speaker variation, advances in deep learning — particularly RNN- and Transformer-based models — have dramatically improved accuracy in recent years. Notable speech recognition models and technologies include: • Whisper (OpenAI) • DeepSpeech (Mozilla) • CTC (Connectionist Temporal Classification) • End-to-End ASR Key applications of speech recognition: • Voice assistants (Siri, Alexa, Google Assistant) • Automatic captioning and transcription • Automated phone response systems and voice bots • Meeting transcription and minute-taking • Smart home and in-car voice control Speech recognition is an important AI technology that enables hands-free interaction and more natural user interfaces, and its adoption continues to expand across both business and everyday life.
