I have found that my Pixel with CalyxOS and microG doesn't have any text to speech engine. So the maps apps work, but with no turn by turn audio.

RHVoice is a free and open source text-to-speech output engine for Android. Try it out:

- F-Droid: https://f-droid.org/en/packages/com.github.olga_yakovleva.rh...

- GitHub: https://github.com/RHVoice/RHVoice

Alternatively, if you prefer Google's closed source text-to-speech engine (that is preinstalled on most commercial Android devices), you can download Speech Services by Google through Aurora Store:

Instructions for configuring the default text-to-speech engine on Android are here:

Most navigation apps come with their own voice banks for turn-by-turn navigation audio, and installing a text-to-speech engine isn't necessary for these apps. However, Organic Maps (which is a recommended app in the CalyxOS setup wizard) doesn't, and it relies on the default text-to-speech engine.

Thanks! I didn't know about RHVoice. I tried installing a couple others I found through searching F-Droid, but nothing worked. I just installed RHVoice.

Thank you for that insight! My comment was based on some (older) Reddit comments. I'm glad to hear there are working apps.

If you're not sure whether an app is compatible with microG or a flavor of Android without Google Play Services, Plexus is a helpful database of crowdsourced compatibility ratings:
