## vowelchart_variation.jpg

The image is a graph that plots two variables: First formant frequency (F1) on the x-axis in Hertz (Hz), ranging from 0 to 1200 Hz, and Second formant frequency (F2) on the y-axis also in Hz, ranging from 500 to 4000 Hz. The graph is divided into several regions or clusters, each representing different vowel sounds.

Each region is labeled with a letter indicating the type of vowel sound it represents:
- **i** and **ii**: These are likely representing front vowels.
- **e**, **ε**: These represent mid-front vowels.
- **a**: This could be a central vowel.
- **æ**: This might indicate an open-mid front vowel.
- **o**: This is typically associated with back vowels.
- **u**: This represents the highest back vowel.

The regions are outlined in black and appear as elongated ellipses, suggesting that there can be some variation within each vowel sound. The labels for these vowels (i, e, a, etc.) are written inside or near their respective clusters on the graph.

There is no additional text or diagrams present other than the axis labels and the vowel labels in the regions of the graph.
