I've seen some people attempt to make a voice gender recognizer through machine learning, but nothing that has actually worked well. I'm not an ML expert, but I expect they're overfitting on just a small subset of accents and specific formants. The one I played with (can't find the link) was just trying to show weight vs resonance, and it got very confused by my voice. I am never misgendered from my voice but I (intentionally) have a slightly deeper femme voice than what it had been trained on.
IMO, the best way to learn to control your voice is to learn to hear variations in size, weight, pitch, open quotient, prosody, etc. From there you can become your own coach so you're not focused on an app while having a real world conversation with someone. Would a gamified version help? Possibly.

More or less everything changes. For trans men who are on HRT the voice's lowest pitch will get lower, as it would for someone AMAB going through puberty (since a second puberty is literally what's happening on HRT). Trans women do not get any voice changes from HRT though, so they train to raise their larynx when speaking to get up into the "perceived female range."
But pitch is far from the only thing that someone gendered one way or another in western culture (and presumably elsewhere). Resonance, weight, breathing patterns, word choice, and prosody all matter too. That's way too much to go into in a post here on HN, but the easiest one to understand is resonance or "size." Female-perceived speakers have higher resonance / smaller size. This means that some of the higher harmonics are amplified more than the lower harmonics, an it's called a "small size" because the actual resonating area from the larynx to the tongue is made smaller (mostly through tongue placement). Male-perceived speakers do the opposite, creating a larger space for resonance and resulting in a lowered resonance.
I know quite a few cis people who are also going through some of this training to help with their voice acting, or even just for fun.
There are a lot of good (and unfortunately some bad) resources online for trans voice training in both directions. My personal favorite (and where I started my lessons) is Seattle Voice Labs, but Online Vocal Coach / Vox Nova is also a great resource.
The ability to switch mid-sentence is mostly just something I discovered I can do and is fun. But the ability to pass as my real gender is something that helps me feel safe. And when needed, being able to occasionally pass as my prior gender (e.g., when calling my bank until I can change my name/gender legally), it also quite useful.
I'm referring to speaking, not singing. After a _lot_ of work, I can speak passably as a woman or man and switch freely between the two. Depending on context I generally choose just one for the entire conversation, as switching tends to cause whiplash in the listener (^_^).
Vocal lessons are both a lot of fun and a lot of work. I haven't been using any voiceprint systems but I know most humans are unable to tell that my trained voice is the same physical person as my old voice. Would be curious to find out if an AI voiceprint system can discern whether it's the same or not.
As a trans woman who started transitioning at 43... I agree 100%.
This article mostly discusses waist size, for which I'm in the lower quartile. But after 40 years of testosterone poisoning my underbust is above the median. Finding clothing that fits and is flattering is really difficult!
A few years back I discovered that the third-party licensing files we had used in the '90s would roll over in 2016. The format used four ASCII digits for the number of days in an otherwise binary file and the epoch was the founding of the licensing company, sometime in 1988. If they had just used a 32-bit integer instead it would have saved me a lot of headache!
DEC WARS is full of great computer jokes. It's a 1983 Usenet posting by Alan Hastings and Steve Tarr: https://www.bsd.org/decwars.html
> It is a period of system war. User programs, striking from a hidden directory, have won their first victory against the evil Administrative Empire. During the battle, User spies managed to steal secret source code to the Empire's ultimate program: the Are-Em Star, a privileged root program with enough power to destroy an entire file structure. Pursued by the Empire's sinister audit trail, Princess _LPA0: races aboard her shell script, custodian of the stolen listings that could save her people, and restore freedom and games to the network...
I particularly enjoyed _Everything and More: A Compact History of Infinity_ by David Foster Wallace. It gave me a new appreciation of not only the last two centuries of math, but also the english language and the abuse of sentence structure, asides, and footnotes[1][2][3] for educational and entertainment purposes.
