What refers to the production of recognizable speech?

Articulation refers to the physical process of producing recognizable speech sounds, which involves the movement and coordination of the lips, tongue, and other speech organs. It is essential for clear communication as it determines how well speech can be understood by listeners. Effective articulation ensures that words are pronounced correctly, making it easier for an audience to comprehend spoken language.

While pronunciation pertains to the accuracy of sounds in words, and fluency relates to the flow and ease of speech, articulation specifically focuses on the clarity and precision with which sounds are produced. Expression involves conveying emotions and enthusiasm through speech, but it does not specifically address the mechanics of speech production. Therefore, articulation stands out as the correct answer for the production of recognizable speech.
