Posting here, as this has more to do with the human voice itself than electronics.

I am planning to build a simple human voice synth, but I couldn't find much on the internet. The overall plan is to generate a signal, pass it through about 10-ish bandpass filters and adjust each filter's gain to create speech.

For my source signal, I found this, which seems to be the sound generated by the larynx before passing through the throat and mouth. From what I read online, a relaxation oscillator or a sawtooth wave seems to be a close approximation of it.

One of the things I am struggling to find is the frequency components corresponding to certain phonetics. Though I am pretty sure it is either because I can't find the right keywords or because SEO ruined the internet.

US2121142A is the patent for Voder, the first human voice synthesizer by bell labs. It has a similar structure to what I've been modeling in my head. Should I just use the frequency values here for my bandpass filters or should I use something else?

I don't like acidity in my coffee much. Stuff I get from my moka pot on the other hand was always very acidic.

Recently I bought a bag of very good, beautiful smelling beans from my favourite coffee shop and brewed it on moka pot. The results are still the same, it almost tastes like lemonade. It is undrinkable amounts of acid in there.

I use the 1zpresso Q Air. I tried nearly every grind setting between 1.6-0.9 (chart, please click). Always the same result.

I also tried starting with both hot and cold water. No difference.

I do not tamp my coffee and flatten it nicely by shaking the basket. I don't overfill the basket.

My moka pot is 2-3 years old and I might need to change its gasket, wonder if that has anything to do with it but i doubt it since the gasket still seals pretty good except for a 5-10mL water leak every brew.

I have 91 flatpaks, and it is my primary way of getting apps. But the (not very shared) dependencies have been bothering me lately.

I was primarily drawn in because Gnome Software has a cool UI and because I wanted the magic of one-click installs. I heard a lot of things about Flatpak and gave it a try.

I have a relatively small 72GB BTRFS root partition with zstd:1 (lowest) enabled. I think disk compression helps with the Flatpak dependency mess, as I only have 60% disk usage currently.

Idk how much extra RAM my flatpaks use, but I don't want 4 versions of the same dependency taking up space in my RAM. Thought about enabling zram to compensate for this. As different versions of the same library in RAM are easy to compress.

I don't think this compression mentality I instinctively adopted is healthy. Make stuff reliable in expense of storage/ram -> compress storage/ram in expense of proc. power

Another thing is slow Flatpak downloads. I have a gigabit connection, and Arch mirrors generally work around 30MB/s with WiFi. Flatpak, on the other hand, hits at max. 5MB/s with its "CDN"

Overall, even though it's kind of ugly, I absolutely love the "don't think about it" mentality of flatpaks. It just works most of the time. I simply use the system package manager for programs that heavily interact with the system (like IDEs, management stuff, and so on)

I am interested in hearing your opinions.

i couldn't upload a video so it's a link

Hi. I am currently using google drive mounted with rsync (encrypted) to stream files over my VPS since my VPS provider charges a lot for extra storage compared to google. I have offline backups of the said data at home

I currently have a 100GB google drive plan and it's working suprisingly great. Also it's cheap in my country due to regional pricing

Now, as I learned, Google keeps your files for 2 years after you cancel your extra storage subscription. It also doesn't allow you to upload anything which locks up Gmail but that doesn't matter if it's an alt account. So, can I just create an alt account, buy a 1 month subscription, upload everything, cancel it, then read it using rclone? Does Google restrict api access (for rclone) on drives with expired subscriptions?

Yeah I know I'm stretching this a bit too far but I just wanna know

Hi there. My guide is currently hosted at survival.aesistril.com. I wrote some stuff but it's really hard to write every guide by myself.

My goal is to create a easy to follow guides for the average joe and compile every other guide into one web page. I want to be able to link this whenever a relative or a friend asks me how to get rid of x

Name and URL suggestions (under .aesistril.com subdomain) are welcome. I am currently using open source hardware icon because it looks cool

I am using the CGA color palette and I would appreciate if you don't use any other colors. Not a strict restriction though
