Adjusting Output Tone in Email Communication

I’ve noticed lately the tone of the produced output is becoming overly formal and sounds quite different from my input. I end up going through the results and changing it to sound less formal, more like myself. It has also been missing key points in its output, which I go back and put in. It’s still excellent at taking my meandering speech and making it organized, but I’m not loving the added formality. Is there a way to suggest tone? This is mostly in emails, and my tone is different depending on the person I’m emailing. Thanks for all the work, blood, sweat and am sure tears you’ve put into this!!
