callrecorder-skvalex VS Athena

If you have root you can try this - https://github.com/Magisk-Modules-Repo/callrecorder-skvalex

Call Recorder - SKVALEX is the module needed to record calls using the closed source call recording app.

Hello Guy, to record your calls you can use this magisk module : https://github.com/Magisk-Modules-Repo/callrecorder-skvalex I use it for my business about 1 year, and he work like a charm ! For the automatisation, you can take a look to Tasker !

Again: Some users reported in this subreddit that SKVALEX found in Magisk Manager works if rooted with Magisk.

This setup can be used to create a 'push button' assistant (which is in fact what I am in the process of setting it up for) where you quickly record your command, and once finished it runs through the whole processing pipeline. I will be releasing more python/java scripts to do just this, and eventually turning it into a native Android app once I've formalized some of the design. I figured it was something people in this sub might be interested in. You can get the APK, the sample launching script, and the setup instructions on my Github. If you're interested in following the project you can do so at r/SapphireFramework

This project is still in early but you could like it https://github.com/Tadashi-Hikari/Athena

Google Assistant: Dicio is already on F-Droid but it won't get what you are saying. Possible actions are limited. There's also Athena that's in development, though it is not ready for any kind of use. Depending on whether you need some sort of an accessibility service, you can get away with ditching Ok Google / Alexa / Cortana / Bixby. TalkBack should help with it too.

Along with what you said, the Athena project also seem like interesting - even though you have to build it. Yet this video indicates that the developer knows what he is doing

Athena - intends to completely replace Google assistant,
