The frequency for my vowels and the downloaded sound are pretty similar. /i/ is high, /u/ is low, and /æ/ is mid. two people’s formant frequencies might differ because of the different vocal folds, language background and accents, and age (children and adults speak in different frequencies) https://seaindia.in/blogs/human-voice-frequency-range/#:~:text=A %20Female%20voice%20frequency%20range,Harmonics%20is%20900Hz %20to%208KHz . The source-filter theory describes speech as a sound made by the vocal folds and filtered by the vocal tract. Different vocal tract results in different formant frequencies. The shape and size of the filter depend upon the shape of the vocal tract.
