Why does the stop-consonant /p/ sound different when followed by different vowels?

💡 Explanation

The sound of /p/ changes because coarticulation causes anticipatory adjustments in the vocal tract configuration to prepare for the following vowel, therefore altering formant transitions. The acoustic properties of the consonant are then influenced, rather than being static due to independent articulation.
