If you gotten results before please read!!

Thank you for taking the time to read this! I am currently in the process of making my own subliminal. I just want to know what I can do to make mines better, I heard using your own voice is better than AI. But I'm still wondering if sound, layering, length, format of affirmations, etc plays a part of the effectiveness of the subliminal. Since assuming you've gotten a result from a subliminal, do you mind telling me what sound it used, the length, if the affirmations were layered, etc? I'll greatly appreciate it ❤
