Technical Definition

The ability of a machine to identify spoken words and convert them into human-readable text.

How it works

Speech recognition, also known as Automatic Speech Recognition (ASR), enables computers to accurately transcribe spoken language into text. This involves processing acoustic signals, segmenting speech into phonemes, and mapping these to words and sentences. Deep learning, particularly recurrent neural networks and transformer models, has dramatically improved ASR capabilities, making voice assistants and voice-controlled interfaces commonplace.
