Key things to know about automatic speech recognition
ASR technology decodes human speech and converts it into digitised text, transforming human-computer interaction modes.

Headline
ASR technology decodes human speech and converts it into digitised text, transforming human-computer interaction modes.
Context
In the past, people needed to use input devices such as keyboards to give instructions to computers, a method that required cumbersome input operations and time. However, with the continuous development and refinement of Automatic speech recognition (ASR) technology, people can now interact directly with computers through speech, achieving a more natural and convenient human-computer interaction method. Through ASR technology, individuals can easily use speech to open applications, search for information, initiate calls, and perform other tasks, no longer relying on cumbersome input operations. This makes human-computer interaction more intelligent and efficient. ASR technology is a technique based on machine learning and signal processing, among other technologies. It converts human speech into digital signals that computers can process, recognising them as corresponding text, commands, or operational instructions.

Analysis
ASR technology typically consists of three main parts: signal processing, speech recognition, and result processing. Signal processing involves transforming raw audio signals into a form suitable for speech recognition, such as noise reduction and speech enhancement. Speech recognition entails converting the processed audio signal into text form recognisable by computers, often achieved through word or phoneme recognition. Result processing involves converting the text recognised by the computer into readable text output.
