Imagine you throw a door on your finger. Often, no sudden blow of pain creates a voice response. Maybe “Ouch!” Or leave a cry or a loud shout. But do the sounds we do in such moments differ between cultures?
Humans are humble vocalities. Scientists shout, complaining, complaints, complain, complain, complain, complain or scream. In addition, our species uses interjections to express emotions. One word words are such words, such as “Ouch” or “wow”, they don’t match other words grammatically.
Sent vocalized and interjections have been seen in all human cultures studied. However, scientists still do not know how these sounds can change around the world or why they can do it. In recent research, we have address this question The sound of the vowel is focused on sounds based on pain, disgust and joy over world languages. We wanted to verify whether interjections and vocalizations that indicate these emotions consistently with the same vowels and vocalizations that are consistent. What we have found can offer traces of the evolutionary history of language and voice communication.

The central idea of driving our work was that people did not arbitrary. Instead, we believe that these sounds have evolved to protect communication functions. For example, pain shouts are often loud, hard and hard to receive attention and attention to the attention of the audience. They are also essentially produced with a wide spacious mouth, which forces the vocalizer (a) vowel sound (as “cat”). Give it tested. See whether you can say “ski” or “knee” with a wide open mouth. You will find that it is almost impossible (i) to create these vowels with your jaw! Instead, vowels will be easier to create when our lips, tongue and jaws smile.
Several sounds matching the idea that matching particular emotions, the researchers found that words will link together with particular vowel sounds or perceptual associations. For example, people in several languages are smiling (i) the vowels tend to link positive and bright things.
To build these ideas, vocalizations and interjections associated with emotional experiences, we decided that there are specific vowels of pain, joy and disgust with specific vowels. In addition to predicting that pain interjections would have a large number of vowels, we were planning that joy would have excessive presentation of vowels (i). In addition to disgust, we expected a greater proportion of what they are called vowels like Schwa, such as “Uh”, an eager or complaining of a person.
To test our predictions, we gathered more than 600 pain, disgust and joy, African, Asia, Australia, Europe and Latin America dictionaries. We also used large language databases to collect thousands of words from these languages. Then we statistically compare the proportions of different vowels in the general lexicon of each language in emotional interjections.
As a second step, we asked English, Japanese, Mandarin, Spanish and Turkish speakers without using words to indicate pain, disgust and joy. With acoustic analysis, 375 vowels of these vocal vocal vocabulary measured by measuring voice tract resonances, or part of the air path used to produce voice in each vocation. (Because these resonances are planned from vowel vowel path, they measure how the vowel is producing when a person who is producing.)
Our results revealed the interjections of the planned pain (A) with a single vowel and diphthong (AY “or” OW “or” OW “). The joy and disgust did not show strong vowel models that were consistent among cultures .
But when we ignore the interjections and looked broadly on vocalizations in non-vocal vocalities, we found specific vowel signatures for each emotion. As announced, the pain shouts (a) were more open vowels (a) with joy expressions (i) more vowels, and disgust had more central vowels such as Schwa, such as “Uh”.
Most human beings can convert certain emotional experiences to communicate, but pain, in our research, creating the same as the same vowel patterns between cultures, whether people produce noise or interjections. This suggests that pain interjections can be the origin of ezistic vocalizations. These findings also accept the idea that some words may not be arbitrary or random. Rather, somehow, they may be acoustic forms that reflect their meaning or communicative function.
The study of voice voice and interjections is still very limited, especially the work that studies comparisons between cultures and languages. These results are the first steps in human behaviors that we expect to be a long line of research in the form of form function, with the aim of throwing new light in voice behaviors. Meanwhile, make sure you do your finger and cry in response, most people understand the culture or language.
