This video was interesting to me: https://www.youtube.com/watch?v=dNQyubd9ARc&t=60s in it you are asked to shout "I like crickets" <In your mind> and then to whisper "I like crickets" again, in your mind and not out loud.
The presenter then claims, "The volume is the same because you can't change the volume of the voice in your head, only the tone and pitch."
My experience of trying this is that I can produce the phrase "I like crickets" in my mind but I have no conception of what it means to "shout" or "whisper" this in my mind and the idea that there is tone or pitch to the representation is meaningless to me.
I can think in words so that I can prepare to write something (like this) but there is no audio. I'd say it's more like a stream of words on a screen except that there is no screen, it feels more like a buffer. The experience is the same as reading to me, no audio, just a stream of words.
My partner says she hears her own voice in her head and it's quite critical, prompting her to action. I feel motivation to do things but there is no voice.
Can someone report on their experience with the crickets experiment above, do you hear a voice, can you change its volume or tone?
