This is a diagram of two oral cavities where phonetic sounds are formed. Animals can produce vowel sounds and musical notes can be used to imitate vowels. Facing right is the consonants chart. Facing left is the vowel chart. The vis-a-vis presentation is my contribution but I did not include the letters. Your home work assignment is to search engine the term phonetic chart diagram in image mode and review your preferred JPEG. This is how we all should have learned our ABCs, with the help of diagrams like this! The Nosov vowels are A=Ape, O=Open, E=East, I=In, O=Offer, A=Apple, U=Us and R=Ripe semivowel? The consonants are G=Got, K=Kite, N=Nice, D=Day, S=Sane, V=Vine, L=Lamp and Z=Zigzag.
