Dicio is nice, but doesn’t have many features (not in my German language) and has no STT, as far as I can see.
Genie Smart Assistant looks nice, but it doesn’t seem to have an Android app.
I’ve search a lot, but didn’t found any usable STT app for Android 
besides Google’s GBoard
Dicio: not many features, but dictation works in german if you downloaded the accompanying model (the small one seemed good enough). I think it’s a matter of integration.
On github you can find “Sayboard” that is vosk+keyboard IME as app, but it’s very barebones and downloads I think the large models (gui is hard to click in darkmode), taking lots of space - so I didn’t link it yet.
LocalSTT isn’t publicly packaged yet afaik (beyond the catalan/spanish prebuilt) so I can’t speak to is quality, should give this a go
Edit: misstated - yes not IME input through Dicio. I meant to say “it will faithfully translate your sentence to text”. Dictation really is not yet a function, it’s command / assistant focused

I noticed today that /e/ did experiment with Vosk ~1yr ago and packaged alphacep/vosk-android-demo with additional integration (choose language) as foundation.e.voice. You have to sign the apk yourself before install.
If you activate it as input method (slide to on as for aosp-keyboard) you can use it through the mic icon on any input field… though when I do, I’m blind to how to return to text input and am stuck

Go to Settings and deactivate the input method again 
.
At least that’s what I did to get my normal keyboard back, perhaps there’s something more convenient?
But the speech to text works really well, I was pleasantly surprised.

Thanks for your hints. Basically I’m just a user who looking for a dictation app that is Open Source and is relatively easy to install on Android. It should work rather reliable (not many bugs) and the quality of STT should be acceptable and in my language (German). It should be possible to integrate the STT app into a keyboard.
I understand that LocalSTT, Sayboard or foundation.e.voice may be candidates for this.
It is recommended to try out foundation.e.voice
…there are no easy options currently, [only] prototype stage…
Android STT Dictation
LocalSTT - see Forum
Sayboard
foundation.e.voice (based on vosk) - Package signing required → Forum → more Info + (recommended)
GBoard from Google - available on Aurora Store. Can be used in combination with Shelter (a privacy app). It’s not very practical to often switch between Gboard and an Open Source Keyboard app. I.e. freeze and unfreeze Gboard app. Also, Gboard installed with Shelter can only be used with Shelter installed apps. See forum
Elivia - no APK available
Mycroft - no APK available. It’s a smart Assistant hardware box
Mozilla DeepSpeech - no APK available. It’s just a model for developers to be used
Vosk - no APK available .it’s a backend that doesn’t work on it’s own.
Smart Assistant
Dicio - Android (F-droid) APK available
Mycroft - hardware box
Genie - no Android APK available. Only for Linux

nice overview. Yes there are no easy options currently, prototype stage.
For the voice/text method switch: I had System → Accessibility → Voice recognition → Shortcut for VR enabled when fumbling around - that icon stopped the keyboard symbol in the bottom right to show up.
With this out of the way, I’d recommend you to sign the foundation.e.voice apk (4 commands) and give it a try. You’ll need android sdk tools. If you run a debian based Linux, those are packaged already.
zipalign -p 4 app-release-unsigned.apk app-release-unsigned-aligned.apk
zipalign -c 4 app-release-unsigned-aligned.apk
keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app
apksigner sign --ks-key-alias app --ks my.keystore app-release-unsigned-aligned.apk
adb install app-release-unsigned-aligned.apk
You’ll need to enable both input methods in the Language and Keyboard: AOSP keyboard and the newly added Voice Recognition.
Before usage, start the VR App and let it download the language model (~50mb?)

On my phone it’s quite simple to switch: when both keyboards are enabled, tere is a small button/icon that appears to the right of the Recents button when either keyboard is active. Pressing this will allow you to switch between keyboards

I use Anysoft keyboard and I can’t see a button to switch between keyboards. Even if there was a button, I can’t switch to Gboard because I can’t see it in my Android settings. This is because it’s installed with Shelter and I can use Gboard only with Shelter installed apps. However, my main Apps I would use Gboard with are not Shelter installed apps (e.g. chat app, car navigation or note app).
Installing Gboard without Shelter is not an option for me.
@tcecyk thanks for your hints. I’ve updated the summary and will try out foundation.e.voice.
I don’t use Shelter. Gboard is installed in the ‘normal’ profile, so switching in easy
I can switch to different keyboards and language settings by press and hold the “space”. I think there is a specific setting for this.
it’s not working for me with Anysoft and even if it did, the gboard keyboard would not appear there since it’s installed in Shelter.
I know that the space bar supposed to work with Anysoft and other keyboards but I dunno why it’s not working for me and I also don’t need it currently.
Finally Dicio has released a working STT app version of Dicio. 
It is a first version, so don’t expect too much (e.g. there are not punctuation marks), but I find it useful and it save’s me time with dictating text for SMS, chat or notes vs. writing it with the keyboard.

True. Works quite good for me too.
Dicio seems to recognize text well enough. Nice!
I’m a bit lost in this thread… is there some way to trigger Dicio to input text instead of me typing, in any arbitrary app?
I can copy and paste what I say into Dicio, but that’s quite a few taps (see below). I’m looking for something more like what gboard does when you tap on the mic icon (and I’d rather not use gboard).
Right now my “quite a few taps” process is to:
- open Dicio
- touch the hamburger menu icon
- touch “Speech to text service”
- say something
- touch the copy button, and finally:
- paste that text into another app
I tried fiddling with Android OS settings a bunch and was able to set Dicio as the “digital assistant”, but this doesn’t seem to do anything useful.
if you use another keyboard app (AnySoftKeyboard) it will recognize the availability of Dicio on microphone-tap. The service will not be instantly available though. System IME integration as voice input (or by intent) is lacking currently.
For both issues there are entries at:

My recommendation is Futo for several reasons.
- It has an extremely good recognition of language. So most words will be recognized correctly.
- It recognises in contrast to Dico capital letters and the punctation and end of sentences.
- If you are speaking more than one language it can be set to automatically detect the language. It will recognise and switch to the other language automatically.
- Completely offline
- No known trackers

Interesting topic and information, thank you all!
When activating Futo it says that the app will be able to read all passwords on a site you use it, is that the same for all STT models?
Or shouldnt I worry about it and its even a good sign they tell me?..

That appears to be the same for every input app (Keyboard, voice app) you may add. Just try to deactivate a keyboard and re-activate it and you’ll see that you’ll get the same message. The app is open source and offline. So no data/passwords should be transferred anyways.

As Lyerbird said, it theoretically shouldn’t be an issue. If you’re worried about it sending data, you can always take away it’s ability to access the internet from the Settings app. I’ve done this with a few privacy invading apps such as Gboard, and the Pixel camera app.
Do know that FUTO apps use a weird pseudo open source license. The code is viewable, but they can take down forks of the project for any reason. Not ideal imo, but certainly better than Gboard.

The Futo licence an be found here. The do say:
This temporary license is intended to protect our intellectual property while we work towards a more open and permissive license. This license is subject to be replaced with one that will grant you more rights, not less.
which sounds reasonable to me.
