Close Front Unrounded Vowel
/i/ is a close front unrounded vowel. The tongue is raised as high and as far forward as possible without creating friction. Commonly found in the vowel of English "see" or French "si".

Description
Close front unrounded vowel, as in English 'see' or French 'si'. The tongue is raised as high and as far forward as possible without creating friction.
Pronunciation
/i/Close front unrounded vowel
Close-Mid Front Unrounded Vowel
/e/ is a close-mid front unrounded vowel. The tongue position is higher than /ɛ/ but lower than /i/. Commonly found in the vowel of Spanish "peso" or French "été".
Open-Mid Front Unrounded Vowel
/ɛ/ is an open-mid front unrounded vowel. The mouth opening is larger than /e/, and the tongue position is slightly lower than /e/. Commonly found in the vowel of English "bed" or French "mère".
Open Front Unrounded Vowel
/a/ is an open front unrounded vowel. This is the basic open front vowel, with the mouth opened to its maximum. Found in French "patte" and many other languages.
📖 A Comprehensive Guide to the Vowel Chart
The vowel chart is one of the most representative diagrams in the International Phonetic Alphabet (IPA) system. Through a side profile of vowel articulation, it visually displays the three major dimensions of each vowel: tongue height, tongue backness, and lip rounding. This interactive vowel chart is not only suitable for phoneticians and language teachers but is also an important aid for broadcasting training and language learners. It solves the problem of difficulty in intuitively perceiving the relative position of the tongue during traditional audio imitation. By visualizing the articulation process, it helps learners understand the pronunciation principles of each sound from a physiological perspective, thereby mastering standard pronunciation more efficiently.
1. Vowel Chart Content Analysis: Detailed Analysis of Four Phonetic Symbols and Articulation Features
The vowel chart displayed on this page clearly presents four core front vowels: /i/, /e/, /ɛ/, and /a/. These four phonetic symbols show a clear gradient in tongue height: /i/ is a close front unrounded vowel with the highest tongue position, where the tongue surface is close to the hard palate, the oral passage is narrowest, and the timbre is the most "tense"; /e/ is a close-mid front unrounded vowel with a slightly lower tongue position than /i/ and a slightly larger mouth opening; /ɛ/ is an open-mid front unrounded vowel with a further increased mouth opening and a lower tongue position, commonly found in the vowel of English "bed"; and /a/ is an open front unrounded vowel with the lowest tongue position and the maximum mouth opening. These four vowels are all unrounded vowels. By observing the subtle spacing between the four curves, learners can intuitively grasp the decisive influence of mouth opening and tongue height on timbre.
2. How to Use the Side Profile on This Page for Practice
To practice pronunciation using the side profile on this page, the following method is recommended: Step 1, locate the tongue position. Observe the colored curves and determine the position of the highest point of the tongue dorsum for the target vowel to establish a visual impression. Step 2, imitate the movement. Imagine your tongue reaching the position marked by the curve in the oral cavity, paying attention to controlling the height and backness of the tongue. Step 3, listen and compare. Click the curve to play the standard IPA pronunciation and carefully distinguish whether the timbre matches your current pronunciation. Step 4, adjust repeatedly. Combine with the lip shape descriptions on the right panel, adjust your mouth shape and tongue position until the sound produced closely matches the recording. Through the cycle of "observe—imitate—compare—adjust," gradually build accurate muscle memory.
3. Advanced Practice Combining with the Trapezoidal Vowel Chart
After mastering the side profile on this page, it is recommended to combine it with the traditional trapezoidal vowel chart on that page for comprehensive training. The side profile focuses on showing the physiological spatial position of the tongue, while the trapezoidal chart provides abstract acoustic coordinates. You can first feel the muscle memory of tongue raising and mouth opening on this page, then switch to the trapezoidal chart to locate these phonetic symbols in the two-dimensional grid and establish an abstract concept of acoustic space. By combining physiological sensation with abstract coordinates, learners can more firmly master the vowel system, correct pronunciation deviations, and achieve a leap from "perceptual imitation" to "rational control."
❓ Frequently Asked Questions
What is a vowel chart?
A vowel chart is a diagram used in the International Phonetic Alphabet (IPA) system to visually display the three major dimensions of each vowel in the oral cavity: tongue height, tongue backness, and lip rounding. Through a side profile of vowel articulation, it transforms abstract articulatory positions into visual spatial coordinates and is an important tool for phonetics and language teaching.
What is the purpose of the side profile of vowel articulation?
The side profile is drawn based on the physiological structure of the human articulatory organs, showing the oral cavity, hard palate, soft palate, jaw, and lips. It can clearly reflect the position of the highest point of the tongue and the degree of mouth opening when producing different vowels, helping learners understand the principles of articulation from a physiological perspective, which is more intuitive and reliable than simply imitating audio.
How do I read the curve positions on the vowel chart?
The curves in the diagram represent the trajectory of the highest point of the tongue dorsum within the oral cavity. The higher the curve position, the higher the tongue is raised (e.g., /i/); the lower it is, the lower the tongue is placed (e.g., /a/); the further to the left, the further forward the tongue arch is; the further to the right, the further back. By observing the relative positions of the curves, you can quickly determine the articulatory differences between different vowels.
What accent is the audio on the page? Is it standard?
The audio materials on the page are sourced from Wikimedia Commons and use standard IPA vowel recordings. These recordings were made by professional phoneticians and have a high degree of accuracy and authority, making them suitable as a reference standard for pronunciation imitation.
How can I use this chart to distinguish similar vowels (such as /i/ and /e/)?
To distinguish similar vowels, you can first observe their curve positions on the vowel chart. For example, the tongue position of /i/ is higher and further forward than that of /e/. Click on these two phonetic symbols to listen separately and pay attention to the difference in tongue height. Combine with the lip shape descriptions on the right panel and practice comparing them repeatedly to gradually master the subtle differences between them.
Does this chart include all IPA vowels?
This chart mainly displays the basic vowel pairs among front vowels, central vowels, and back vowels, including unrounded and rounded pair relationships. It covers the most common core vowels and is suitable for beginners and intermediate learners to build foundational knowledge. The complete IPA vowel chart also includes more central vowels and secondary vowels. You can refer to the links at the bottom of the page to browse the complete phonetic symbol chart.
