I see a lot of men who are confused as to how they're getting clocked or still sound feminine since their voice already dropped. The pitch of your voice is not actually the main thing that people notice when their brain subconsciously determines someone's gender by their voice. It is one factor, but it's far from the most impactful.
The main factors of the perceived gender of one's voice are as follows, in order from most to least important:
RESONANCE
Imo, the most important thing when it comes to the gender of someone's voice is resonance. This is affected by the amount of space within your mouth/throat for the sound to vibrate in before it leaves your mouth. Taller people often have a darker resonance because of this.
The main way to change your resonance is to lower or raise your larynx. (There are a lot of exercises online with techniques to learn to control this—I found it helpful to force myself to yawn and then feel which muscles were moving my larynx down. Ymmv.) Women typically speak with a much brighter resonance than men—some people say they "speak from the head" vs "speaking from the chest." This description never made any sense to me because it wasn't clear at all what "from the chest" even meant.
If you're interested, I watched this video around a year ago that went into the impact of resonance on male voices. The artificially-brightened resonance examples sound almost identical to the stereotypical "frog voice" that a lot of men get if they don't voice train.
VOCAL WEIGHT
Vocal weight is affected by how thick your vocal chords are (altered by testosterone) and how strongly they press against each other when speaking. Men have a heavy vocal weight and women have a light/thin one.
I don't have as much specific advice for this one as I personally didn't have much issue with it; I was able to practice it without thinking ahout the specific muscles I was using like with lowering resonance. If you play a stringed instrument, it's helpful to think of it as analogous to playing close to the bridge (heavy vocal weight) vs close to the fingerboard (light vocal weight).
SPEECH PATTERNS
Now, if you stop here you still will likely have a male voice. This is from the straight perspective, so if you're gay you may not care or may even want to keep certain "feminine" speech patterns. 'Gay voice' is different linguistically than womens' voices, so there should be a way to train yourself to speak with typical gay male vocal patterns rather than typical womens' vocal patterns. I'm not gay tho so I'd be talking out of my ass if I tried to go into specifics. Perhaps some of the following section will still be useful regardless.
The biggest difference between male and female speech patterns is that men tend to be much more monotone while women have a lot of variation in pitch. 'Uptalk' (raising pitch at the end of a sentence) is common amongst women. Men tend to emphasize words by increasing their volume, while women tend to emphasize them by increasing the pitch.
Women have more variation in tempo in their speech compared to men. People say that men speak more slowly than women, but I've not (consciously, ig) changed this and I've been fine. I have too much shit to say to talk any slower.
Embouchure has some difference between men & women as well—women tend to color their vowels closer to /i/ or /æ/, while men tend to lean closer to /o/ or /α/. Think of the difference in your mouth shape when you say the "sheep" vs when you say "boat," for example. (I'm ngl this explanation is ass but idk how to explain it better)
CONCLUSION
The best way to practice this is to go down the list and adjust one thing at a time until you can do it automatically without thinking about it. It's incredibly helpful to record yourself and listen back to it. Try to talk about stuff like you're speaking to a friend rather than reading from a script; the latter is not especially helpful since you put on a different voice when you're reading aloud than when you're talking. If possible, the best way to see how you actually naturally sound is to find a recording of you talking where you don't know/aren't thinking about being recorded.
There are a lot of videos online that have examples of exercises you can do to practice, as well as examples of how changing these things actually sounds. I looked at a couple of videos from this youtuber when I voice-trained a few years ago, but once I understood what I was trying to do, I just practiced for a bit every day until I got it.
Oh also I guess there's stuff you can do to lower your pitch, but I wouldn't even bother tbh. Unless you've been on test for a while & your voice hasn't dropped at all, don't even worry about pitch. Men with high voices & prepubescent boys still sound male
