Can you guess this note? Perfect Pitch and Physics

The missing ingredient is in our language. Each vowel is a musical note that does not change except with accent and that changes a semitone or two. If my Australian accent says see-saw, there are 2 vowels, each in the pitch of C an octave apart. You may recall movies where opera singers tune their voices by singing me-me-me, also in C. Though I don't have perfect pitch, my relative pitch is enhanced and I have learned 12 musical instruments though I only maintain 6. If I sing a song, it will always be in relative pitch as it will conform to the music I know from the vowels, a skill enhanced by becoming an overtone singer. Here is my video explaining overtone singing and vocal projection.  https://youtu.be/L9uZX2sjOqA
