Voice Recognition Technologies

Automatic Speech Recognition (ASR) is a technology that enables computers to recognize human speech and convert it into text data. With the advancement of deep learning and large language models, accuracy has dramatically improved, and it is now widely used in various fields such as voice assistants like Siri, Google Assistant, and Alexa, call center transcription, medical record creation, and hands-free vehicle operation. As of 2025, more advanced features such as real-time translation, emotion recognition, and multi-modal dialogue are being realized.
