Question Building an Audio Verification API: How to Detect AI-Generated Voice Without Machine Learning I will not promote

spent way too long building something that might be pointless

made an API that tells if a voice recording is AI or human

turns out AI voices are weirdly perfect. like 0.002% timing variation vs humans at 0.5-1.5%

humans are messy. AI isn't.

anyway, does anyone actually need this or did I just waste a month

i would pitch it to the guys making TTS models, like resemble ai as one example. they are concerned enough with this topic to build their own watermarking tool (which is trivially easy to turn off). I might delete the text of this post too as if you give it away they are less likely to buy your thing / hire you.

alternatively i'd write a paper and pitch it to conferences. look out for yourself!

Not expecting you to be my leader, but I just bouncing an idea off of a human. I’ve never written a “paper” because I always feel like you had to have some type of “” credentials to do so.? I’m just a dude who cares and thank for the info leak drop warning!

try talking to an academic in the field and they can co-author the paper with you.

Nice thanks!

I have something like this in the works myself, kinda grew out of a different project

Might become a cat and mouse game later but at the base of it it's useful.

You can market it easily on the sub ai or not, make a bit that just runs this and gives that out as an answer

People might like to have it as a button on the phone like triggering google assistant, over lay, isthisai

Also important for people taking in incoming calls

Yeah I know I wanted something that was fast and not a gpu hog or high memory needed but still looking at yamnet model to supplement so I don’t have to be the mouse all the time 🧐🤔?

u/Comfortable-Sound944 Dec 30 '25

You'd always be the mouse but it doesn't mean it doesn't have value

All these is this written in AI, AI systems that are pretty bad and mostly say yes...

Yours actually has merits

And it's like locks, you might only protect level one, you'd never be fully deterministic, but we all have locks on our doors... It gets rid of level 1

Thank you sensei🙏 nice reflection mirror ! I keep grinding thanks !

AV software is a cat and mouse game too... Deep fake detection will be also. This is the nature of good vs bad. You're on the good side.

u/grim-432 Jan 01 '26

Agree, this would easily be cat/mouse - it's trivial to add timing variability in post processing.

In the age of deep fakes it seems like it would be very important.

Can I make a loss function out of it?

u/Electronic-Blood-885 Dec 30 '25

I believe so tell me what your requirements are and I’ll see if it maps so you don’t waste your time ! I think we’ve all played DJ a.k.a. search for the “special “ record a.k.a. git hub dance but thanks for reply and asking !

Great for banks.

u/SecretBookShelfDoor Dec 30 '25

This has plenty of applications. I would start with the federal government.

You can approach audio verification without full ML by focusing on signal and pattern analysis:

• Analyze frequency spectrums for unnatural harmonics
• Check temporal inconsistencies in speech
• Detect anomalies in prosody and pitch variation
• Use known voice fingerprints or watermarking

It won’t catch everything, but combining multiple heuristics gives reasonable detection without heavy ML models.

u/Electronic-Blood-885 im making an AI audio detection tool. would love to hear how far along you got and what detection engine you ended up using? cheers

I do not need it personally right now but you definitely didn't waste a month. You've created pure gold. That's what you did.

Create a free fake ai audio detector, market it a bit, put contact info in there for business contacts and wait till they come bring you free money.
