Sometimes there are interesting goal conflicts. Consider the lady who told me that she sought me out because she wanted more respect, more authority. I pretend that I don't know that you'd rather die than listen. I play a few statements on the tape and ask for your first impression. As I have you listen and comment on your own voice, I am noticing what you are able to hear and identify and what I will need to guide you to.
Some people are able to notice and describe the characteristics of their speaking quite accurately.
All three descriptions are made by you and all three can be quite different. Now, I give my own feedback. The first thing I do is to point out all the areas that you manage quite well and should not think about changing. This always comes as a surprise. My clients show up with much self-criticism and expect me to be equally critical.
