You do it by making your trained voice second nature. The reason your voice is where you want it while training but not in a conversation is because you have to practice not thinking about maintaining the voice. When you fall into a conversation, you're thinking more about maintaining the conversation and what you're going to say than what your voice sounds like, so you end up just sounding like your default, you need to just practice until your trained voice becomes the default
i will admit i code switch a LOT when it comes to how low my voice depending on who i’m talking to but my best advice would be to try it with strangers and make sure you are mentally aware of how you start speaking before you do. there are some people i genuinely can’t control it around tho (like my parents, close friends, partners, etc) and thats prob cos i feel most comfortable around them
I really struggled with this too. What helped me the most was practicing with real people who I knew I’d never see again. I started with restaurant drive-throughs that aren’t in my normal area, and I really sucked at first, but got much better with time. Then when I was feeling a bit more confident, I started actually going inside stores and restaurants I don’t frequent, and asking where things are or ordering food. Practicing regularly with real people is the only way I was able to improve
