How do you get a less-squeaky and a less annoying voice?

You can work with a voice coach who may be able to teach you to modulate your voice and dampen the squeakiness down.

What do you mean by “I’m in speech”? Is that therapy or a class in school? Listen to a tape of your voice, too. And get some opinions other than that of your sister. She may not be the most objective judge.

Sisters do that kinda thing, but I have actually always wondered about that. I knew a girl in high school who has the tiniest, high pitched voice. She was super cute and sweet and no one gave her a hard time, but I wonder if it matured as she got older. @gailcalled GA

I recommend smoking… Or talking slower, and more gently.

You know take your time and think about what you’re saying.

How cruel sisters can be. I think your voice is lovely just the way it is.

You can consciously pitch your voice lower. Practice. After a while it becomes automatic.

After I had sinus surgery, the tonal quality of my voice changed. It became higher and thinner. No one had told me that might happen. I didn’t like it and made up my mind to change it, so I simply made an effort to pitch it lower until it became second nature.

I was once waited on by a clerk in a store who was an attractive young woman in her mid-twenties with a speaking voice so childishly high and tinny that she sounded like a cartoon character. It was so unexpected that I was nearly startled into laughing out loud, which would have embarrassed both of us. Even for a child it would have been high, and to make it worse she seemed to have a habit of speaking in her own highest registers. She spent about ten minutes helping me, and she had plenty to say. I could hardly bear it. She would have been wise to ask the question you’re asking and then do something to change her voice.

I agree with Jeruba. I had a laugh I didn’t like. I laughed on the in breath instead of the out breath. I guess you call that a horse laugh? I was high school age and it took one session at dinner. I started practicing a laugh on the out breath. My family started laughing at me and we all laughed so hard the new laugh became comfortable for me quickly.
Ask your friends about your voice. You can change the pitch and then practice. Or try different pitches. I’ve heard little old ladies speak with tiny little voices . . . not quite like 5 year olds, but almost. I find this kind of voice wimpy. You’ll never sound like a bass, but you can decide (within reason ) what you want your voice to be. Have fun and good luck.

It’s possible to consciously train your voice to pitch lower, to some degree. I know because I’ve done it, though I couldn’t tell you HOW I did it. I just deliberately force my voice to stay low. You say that you already have a voice coach – ask them for advice.

When I said ‘in speech’, I mean therapy. You know, how to say ‘rs’s. You’re supposed to say ‘right’, not ‘wite’. Yeah, that type. It’s not exactly a voice coach. More like.. speaking coach. She dosen’t work with pitch and tone, she works with conversation, the tongue, and mouth, so you can speak clearly. But I’ll ask her. She might known.

Not recommended, but you could try Frank Zappa’s approach. During the encore of a concert at the Rainbow Theatre, London, an audience member pushed Zappa off the stage and into the concrete-floored orchestra pit. He suffered a crushed larynx, which caused his voice to drop a third after healing. Before you go and try it out, you should probably note that he also had serious fractures, head trauma and injuries to his back, leg, and neck.
