mfcc-rust VS Leon

hey, quick question. do you mind if I use your stft function in the speech preprocessing library I've been working on? we've been trying to add support for doing mel spectrograms to build a runner for openwakeword, but progress is pretty slow because I've been soloing something I really don't have the right background for(I've never directly studied or worked with signal processing)

So I've been working on an speech preprocessing library for rust for a minute now. The tl;dr is it contains functions related to preprocessing audio for use in speech-centric models. I've run into a situation where I'm running against a few conflicting design constraints and trying to figure out the best way to handle state for a set of functions.

we could always use contributors for mfcc-rust/speechsauce(we're planning on changing the name as it's not limited to just computing mfcc's).

The code has comments and in the GitHub issues is written what's missing, the goal is to mimic functionality from NumPy not present in NDArray (a library for maths operations). You can find the code here: https://github.com/secretsauceai/mfcc-rust. Take a look, if you feel that you can give a hand, that would be amazing!!! Let's make a new exciting voice future!!!

This release represents the first phase in the wakeword project, we are working on a Rust wakeword engine based on Precise and a SpeechPy MFCC port in Rust so that user's can run the wakeword easily on their phone and other devices. It is hard to believe that there aren't any current good solutions to running a modern FOSS wakeword engine on a phone in real time. We want to change that and allow everyone access to this technology, with their own wakeword of choice.

It's indeed suspicious. You're sending your voice samples, your various services accounts, your location and more private data to some proprietary black box in some public cloud. Sorry, but this is a privacy nightmare. It should be open source and self-hosted like Mycroft (https://mycroft.ai) or Leon (https://getleon.ai) to be trustworthy.

I literally had this thought a couple of days ago and went down a small rabbit hole looking into it too! There's some stuff out there (I saw Mycroft and Coqui mentioned in the comments already, also check out Leon, Jarvis, and OA although not sure they all deploy to Linux) but ultimately, I just don't think the tech is there yet.

Mycroft is pretty decent and there are a few other similar open source projects if you're interested (https://github.com/MycroftAI, https://github.com/leon-ai/leon)

Take a look at Leon I'm not sure it's what you're looking for but it look pretty awesome.

Leon is an open-source personal assistant who can live on your server. He does stuff when you ask him to. You can talk to him and he can talk to you. You can also text him and he can also text you. If you want to, Leon can communicate with you by being offline to protect your privacy.

There is also Leon - https://getleon.ai. But I’m not using any of the self hosted yet.
