This image displays a scientific chart containing eight individual spectrograms arranged in a grid of two rows and four columns. The background is white, and the graphical elements are black. There are no people or characters in this image.

The vertical axis on the far left represents frequency in Hertz (Hz), with markings for 1000, 2000, 3000, and 4000 Hz increasing from bottom to top. The horizontal axis at the very bottom represents time in milliseconds (ms), with markings for 0, 300, and 400 visible.

Each of the eight panels displays a spectrogram of a specific vowel sound, identified by an International Phonetic Alphabet (IPA) symbol centered below each graph. In these graphs, darker horizontal bands represent formants, which are concentrations of acoustic energy at specific frequencies. Small black arrows point from the left margin toward these dark bands in most panels to highlight them.

Top Row (from left to right):
1.  **Panel labeled [ i ]**: Shows a spectrogram with distinct dark bands. One band is visible near the top around 3000 Hz, another below it around 2500 Hz, and a lower one near 1000 Hz. Arrows point to these frequencies.
2.  **Panel labeled [ ɪ ]**: Similar to the first panel but with slightly different band positions. The upper bands are clustered between 2000 and 3000 Hz. Arrows indicate specific formant locations.
3.  **Panel labeled [ ɛ ]**: Shows bands that are generally lower in frequency than the previous two. There is a cluster of energy around 2000-2500 Hz and a distinct band near 1000 Hz. Arrows point to these features.
4.  **Panel labeled [ æ ]**: This graph shows dark bands distributed across the vertical range, with significant energy visible between 2000 and 3000 Hz and another band lower down around 800-900 Hz.

Bottom Row (from left to right):
1.  **Panel labeled [ a ]**: This spectrogram shows three distinct dark bands indicated by arrows on the far left. One is low, near 500 Hz; one is in the middle around 1200 Hz; and one is higher up around 2800 Hz.
2.  **Panel labeled [ ɔ ]**: Shows a pattern with energy concentrated between 1000 and 2500 Hz. Arrows point to bands near 600 Hz, 1200 Hz, and 2300 Hz.
3.  **Panel labeled [ ʊ ]**: This graph shows a concentration of energy lower down on the frequency scale compared to the front vowels. There are arrows pointing to bands around 800 Hz and 1500 Hz. The texture is somewhat grainier than the others.
4.  **Panel labeled [ u ]**: This final panel shows dark bands primarily in the lower half of the graph, below 2000 Hz. On the right side of this specific graph, there is a distinct curved line or "hook" shape rising from the middle frequency area up towards the top right corner. Arrows point to bands near 500 Hz and 1200 Hz.
