I'm in online therapy but I often imagine speaking in a child like tone.
I've also read that people with cptsd or childhood trauma sometimes have child sounding weak voices. I definitely have that. My voice is more like a 10-12 years old girl than an adult woman. Maybe it's because I'm short, I don't know.

I usually speak in a high and "soft" way. Recently I've recorded myself singing and it sounds like my throat is tense and constricted.
I listened to a lady explaining singing technique and she said that people talk with their throats open and only tense them for singing. I didn't understand the concept of free and open throat... I had to practice for 3 days and I noticed my normal talking voice is richer and more "adult" today.

I guess this came from childhood anxiety and always trying to be quiet and invisible. I didn't even realize I had this weakness in my voice.
Today I'm a little positively surprised by the "richness" of my relaxed vocal cords. My tone is still high but a little stronger. I hope I'll be able to keep this openess and gain even more strength and confidence.

I'm sorry this was off topic but I had to share.
