Which of the following describes a technology that can convert spoken words into text?

The technology that can convert spoken words into text is known as speech recognition. This involves using algorithms to analyze audio signals, identifying words and phrases as they are spoken, and transcribing them into written form. Speech recognition systems utilize techniques from fields such as signal processing and natural language processing to improve accuracy and understand variations in accents, intonations, and speech patterns.

Natural language processing, while related, focuses more on enabling computers to understand and generate human language rather than the input of spoken words in an audio format. Computer vision pertains to the analysis and interpretation of visual information from the world, which is unrelated to audio processing. Robotics involves the design and application of robots and does not inherently involve the conversion of speech to text. Thus, the focus of speech recognition specifically addresses the task of transforming vocal expressions into readable text, making it the correct choice in this context.
