How to get grok to pronounce words correctly?

I am really struggling with getting groks imagine photo to video feature to pronounce words as I prompt them. Sometimes it will be fine, time after time, other times I will end up wasting credits redoing the same thing 10plus times because not one of those times will it speak the prompted sentance correctly. I’m not talking about accents or pauses etc, but about it adding in gibberish or turning the worlds into gibberish.

For example I have tried to get it to say “at least a few million people” about 10 plus 10 times now and I am getting words or gibberish added in, words missed, least being turned to gibberish, and finally it almost said it right but instead of a few million ppl it says “a four man people”

does anyone know any prompting tips or hacks to get it to say what the fuck is typed? I have tried getting ChatGPT to prompt it, tried telling it to enunciate clearly, tried putting commas or full stops between words, tried phonetic versions of words and I am still getting nonsense. It’s not so much mis pronunciation of words, but adding extra syllables or extra gibberish words in between the actual words in my prompt.
