The spelling of "more loudvoiced" is a bit unusual, as "loudvoiced" is not a commonly used word. However, it can be analyzed phonetically using the International Phonetic Alphabet (IPA) as /lˈaʊdvɔɪst/ (loud-voiced) with stress on the first syllable. Adding the word "more" in front of it simply means louder than what is already being described. While it may not be a commonly used phrase, it can be easily understood through its phonetic representation.
