Have you ever wondered how many words you say in a day?

If you’re short on time, here’s a quick answer to your question: The average person speaks around 16,000 words per day.

In this article, we’ll explore the science behind how many words the average person speaks, how it varies between individuals, and some interesting facts about language and communication.

What is the Science Behind Speech Production?

Speech production is a complex process that involves several parts of the body working together. It starts with the brain, which sends signals to the muscles involved in speech. These muscles include the tongue, lips, jaw, and vocal cords. When these muscles move, they create sound waves that are then shaped into words by the mouth and throat.

The Anatomy of Speech

The tongue, lips, and jaw are responsible for forming different sounds that make up words. The tongue helps create sounds such as “t,” “d,” and “l,” while the lips and jaw are responsible for sounds such as “p,” “b,” and “m.” The vocal cords, located in the larynx, vibrate to create sound.

The brain also plays a crucial role in speech production. It sends signals to the muscles involved in speech, telling them when to move and how much force to use. The brain also helps us choose which words to say and how to say them.

The Process of Speech Production

Speech production involves several steps. First, the brain processes the information it wants to convey. Then, it sends signals to the muscles involved in speech, telling them which sounds to make. The muscles move to create sound waves, which travel through the throat and out of the mouth as speech.

As we speak, our brains are also constantly monitoring our speech and making adjustments as necessary. For example, if we mispronounce a word, our brains will send signals to the muscles involved in speech to correct the mistake.

Factors Affecting Speech Production

Several factors can affect speech production. For example, certain medical conditions, such as stroke or Parkinson’s disease, can affect the muscles involved in speech. Injuries to the head or neck can also affect speech production.

Additionally, environmental factors can affect speech production. For example, loud noise can make it difficult to hear oneself speak, which can lead to changes in speech patterns. Stress and anxiety can also affect speech production, causing stuttering or difficulty finding the right words.

How Many Words Does the Average Person Say?

Measuring speech production is a complex task, and the number of words an average person says per day can vary based on a variety of factors. However, studies have shown that the average person speaks around 16,000 words per day.

This number can vary depending on a person’s age, gender, and occupation. For example, men tend to speak less than women, and people in certain professions that require a lot of communication, such as sales or teaching, may speak more.

Variations in Speech Production

Interestingly, the number of words a person speaks per day can also vary based on their social situation. For example, a person may speak more or less depending on whether they are alone or in a group, or whether they are talking to a friend or a stranger.

Another factor that can affect speech production is a person’s mood. Studies have shown that people tend to speak more when they are in a positive or excited mood, and less when they are feeling down or depressed.

Other Interesting Facts About Speech

  • On average, women tend to speak more than men, with some studies suggesting that women speak up to 20,000 words per day.
  • Children typically speak less than adults, with toddlers averaging around 250 words per day and pre-schoolers around 2,000 words per day.
  • People who are bilingual or multilingual may speak more or less depending on which language they are speaking at the time.

Why Does Speech Production Matter?

Speech production refers to the process of creating spoken language. It is an essential part of human communication and helps us convey our thoughts, emotions, and ideas to others. The average person produces thousands of words every day, which can have significant implications for communication, speech disorders, and therapies, as well as future directions in speech research.

Implications for Communication

Speech production plays a crucial role in communication. The ability to speak fluently and clearly is essential for effective interpersonal communication. According to a study by the University of Arizona, the average person speaks around 16,000 words per day. However, this number can vary widely depending on factors such as age, gender, and personality. Understanding the average number of words people say per day can help us better understand how to communicate effectively with others.

Speech Disorders and Therapies

Speech production disorders can have a significant impact on a person’s ability to communicate. Conditions such as stuttering, apraxia, and dysarthria can make it difficult to speak fluently and clearly. Speech therapy can be an effective way to treat these disorders and improve communication skills. By understanding more about speech production, therapists can develop more effective therapies and treatment plans for those with communication disorders.

Future Directions in Speech Research

The study of speech production is a rapidly evolving field, and there is much that researchers still do not understand. Advances in technology and neuroscience are providing new insights into how speech is produced in the brain and how it can be improved. For example, researchers are exploring the use of brain-computer interfaces to help people with communication disorders communicate more effectively. As our understanding of speech production continues to grow, we can expect to see new and innovative approaches to improving communication and treating speech disorders.


In conclusion, the average person speaks about 16,000 words per day, but this can vary widely depending on factors such as age, gender, personality, and context.

Understanding how speech is produced and how it varies between individuals can have important implications for communication, speech therapy, and other areas of research.

So the next time you’re talking to someone, remember that every word counts!
