Informal pronunciation refers to speech that deviates from standard pronunciation rules in a casual or relaxed setting, such as with friends or family. This can involve using slang words or phrases, reducing the number of syllables in words, or speaking more quickly. Informal pronunciation is often more casual and relaxed compared to formal pronunciation, which follows strict pronunciation rules.
