I'm trying to record as little lines as possible, and 5-mora was very exhausting for me. 7-mora isn't as much help either. I'd really appreciate your help!
The Insanity Basics reclist maximizes the efficiency of the string patterns and removes all non-standard Japanese syllables. The string length is irregular, but this is a necessity because of the numerous exceptions in Japanese syllable structure. https://utaforum.net/resources/insanity-basics-reclist.310/
