The word "cadden" does not seem to exist in any recognized English language dictionaries. However, based on its spelling, it could possibly be pronounced as /ˈkædən/ with the stress on the first syllable. This would mean the word is pronounced with a short "a" sound, followed by a voiced "d" sound and ending with an unstressed schwa sound. It is important to note that without any context or origin, it is impossible to determine whether or not this is the correct pronunciation of the word "cadden".
