@s710 You can compare with Geekbench 5 scores if you keep in mind that all Vollaphones are variants of Gigaset phones. (Yes, Geekbench is Android based, but it should be a good indication for Linux, too.)
The first Vollaphone corresponds to the Gigaset GS290; I see a single-core score of 150 and a multi-core score of 902. The FP4 is much faster: 642 and 1878.
BTW: The Vollaphone 22 corresponds to the Gigaset GS5 and is somewhere in the middle, with scores 352 and 1296.
You can run Kaldi-based ASR on UBports. This solution needs no Internet and preserves privacy. I am using this for German and English. But this is not an app, only a tool for converting wav files to text.
@melu9wuv Kaldi is a toolkit and far from an easy installation. If more people are interested, I can share a recipe, mabye including ASR models for EN and DE.
The installation of UT on a Cosmo Communicator works for me and others after installing Gemian. Has anybody managed to avoid this extra burden? I am willing to try suggestions on another fresh Cosmo Communicator.
(Could somebody create a Planet subcategory and move my post and others there? That would help ...)
I can add some details. The LED is on and white. The device is getting warm, so in a sense it is hot spot 
@mv I own a VP22 running UT. Dual booting is only possible (currently?), if your device comes with VollaOS. Installation of a second OS like UT is done from within VollaOS. (There are good docs for this on the Volla site.)
Thanks for clarifying and good to hear that it worked. Which file did you use for downgrading to Android 9?
A discussion on a similar topic was started 3 days ago https://forums.ubports.com/topic/6561/oneplus-6t-and-speech-to-text
You can add upstart scripts in user space. Example: put into .config/upstart/local-init.conf:
description "run script local-init"
start on started unity8
exec /home/phablet/local/bin/local-init
and add your commands into the file given in the exec line.
I found some info in the FAQ: which says to do :
Call up the entry "System", "Advanced" and "Volla Boot Manager".
This refers to the Volla OS, which is not on your phone.
Can anyone tell me what to do, I'd love to be able to use this phone!
People have done this, but it is not easy if I recall correctly.
You can contact Volla support who can reflash your phone to a dual boot setup.
BTW: If you have a dual boot phone, remember to never update any of the OSes from within the OS; only the Volla Boot Manager will be ok for this.
@andrew907 Yes, piper has no code for integration into a browser.
@andrew907 The quality of most voices from https://github.com/rhasspy/piper/ is impressive. I use them on some phones with pmOS. (I have no experience in packaging for Ubuntu, so I cannot comment on this.)
@deathmist Good to hear. But I tried the Waydroid Helper method, which seemed to work, but crashed after some minutes of light use.
@deathmist Thanks for the description for the Volla X23. Is there a similar method for the Volla 22 under Focal-OTA2 ?
In the xda-developers page, there are two files labelled OB25.
I bought a used one (for 400 EUR) some days ago. I am still undecided whether to try UBports or postmarketOS first. @krang Is your development channel 20.04 or 16.04?
@s710 Still running OTA-24, i.e. Ubuntu 16.04. I use my phone rarely, so I have no valuable impressions from the user interface.
