Paige,
I think the pitch is only slightly low and that there is still a bit too much resonance, but it's getting pretty close! I think you could pass on that pitch just fine if you eliminated the extra resonance (a small amount of resonance is still good; all women have it -- it's how a voice carries and has a discernible shape when speaking).
I may be wrong, and I am sorry if I am, but it sounds to me like it takes a lot of effort for you to maintain that voice. If this is the case, then I would recommend that you continue to try and keep speaking in it until it's comfortable for you. The elasticity of your voice will expand naturally as a result.
Stranger,
I think your voice might need a higher pitch and to spend less time brushing up against your nose. Have you tried resonating in the front of your chin while speaking from the high back side of your throat? It might make your pitch control easier.
Seras,
I think your resonance needs the most work. I get the impression that your voice is still spending a lot of time in your chest; have you tried to really squeeze the entirety of your voice into your head? I think a higher pitch with your voice in particular may also help hide some of your extra resonance, too.
Angélique,
I think your voice sounds really good! I would consider lowering it ever-so-slightly, though. The more you use your voice, the more you'll become comfortable with it and shaping it how you prefer. I really think you're on the right track and have a good grasp on what to do, and that the kinks will work themselves out over time.
Sam,
I think resonance is likely your largest obstacle. It sounds like your voice spends a lot of time in your throat (particularly the front) and bounces around in your mouth a bit. I'd like to suggest trying to make it feel as though your voice emanates from the top of your throat and funnels only through the middle of your mouth (over the center of your tongue), towards the front of your teeth.
I'm sorry if anything I said to anyone was off-putting or seemed too harsh, my only intent is to be helpful and I did try to phrase my insight as gently as possible. I'm also only speaking from my own experiences and experimentation with sounds, so hopefully what I've suggested is something that travels well between individuals. Good luck to all of you!
