The spelling of the word "rochon" can be explained using the International Phonetic Alphabet (IPA). The sound represented by "r" is produced with the tongue curled back and the little ball at the back of the mouth vibrating. Next, the "o" sound is a short vowel made with an open mouth and the tongue low in the mouth. The "ch" represents two sounds, starting with a plosive consonant made by releasing a burst of air followed by a fricative consonant produced by moving air through a narrow gap. Finally, the "n" is made by vibrating the tip of the tongue against the roof of the mouth.
