How Does the Human Body Produce Voice and Speech?

How Does the Human Body Produce Voice and Speech? Short Description: An explainer (NIH/NIDCD) that shows how the body produces voice and speech through three linked processes: breathing (airflow from the lungs), voicing/phonation (vocal fold vibration in the larynx), and speaking/articulation (shaping sound in the mouth and nose). Ideal as a short primer for courses in anatomy/physiology, speech science, linguistics, or communication disorders.

About Course

The How Does the Human Body Produce Voice and Speech? course introduces learners to the physiological processes involved in human voice and speech production. The course explains how breathing, phonation, and articulation work together to generate and shape speech sounds.

Students will explore how airflow from the lungs powers sound production, how the vocal folds in the larynx vibrate to create voice, and how the mouth, tongue, and nasal structures modify sounds for clear speech. This course serves as a concise primer for students in anatomy, physiology, speech science, linguistics, and communication disorders, helping them understand the biological foundations of human communication.

What You'll Learn

By the end of this course, you will be able to:

  • Describe the three core processes of speech production: respiration, phonation (voicing), and articulation.
  • Identify the main anatomical structures involved (lungs/diaphragm, larynx/vocal folds, oral and nasal cavities).
  • Explain, at a basic level, how changes in airflow and vocal fold vibration affect voice.
  • Summarize how the mouth, tongue, lips, and soft palate shape sound into speech.

Prerequisites

Helpful background: basic human biology (respiratory system) and familiarity with simple anatomy terms (larynx, trachea, mouth/nose).

Who Can Take This Course?

This course is for undergraduate or graduate SLP, Medical and Speech processing learners who need a quick foundation in how voice and speech are produced. Students of linguistics, biology/anatomy, education, audiology and communication sciences can also benefit from this content.
