The sentence landed in LibreOffice Writer after tapping Deliver while the phone stayed on a desk.
Packaged as a .deb and a portable zip for x86-64 Linux, tested on Ubuntu 22.04 under X11.
Across 4 applications on Ubuntu 22.04.5 under Xorg (gedit, LibreOffice Writer, a Firefox textarea, and the VS Code editor), 5 of 5 sends typed into the phone landed at the cursor in each program.
We ran our Linux tests on Ubuntu 22.04.5 under Xorg with an Android 16 tablet over "Local LAN", using sentences typed into the phone and short synthetic-voice clips played into LibreOffice Writer and gedit.
Words on the phone show progress, not the final text.
In GNOME Terminal at a bash prompt, 5 of 5 sends landed on the command line with Ctrl+Shift+V and did not press Enter or run a command.
Do not use FlowMic with xterm or the integrated terminal panel inside VS Code on Linux.
A few common questions
Why does Linux show Input sent (unconfirmed) on the computer after I dictate?
Because X11 gives no read-back from the target window, every Linux send shows "Input sent" with "(unconfirmed)" on the computer and "Delivered" on the phone. "Delivered" means the words reached the computer, not that they were typed into a window, so always check your target window.
Does pasting text from FlowMic overwrite what is on my Linux system clipboard?
FlowMic pastes via the system clipboard and restores your previous text afterward; across all 4 applications on Ubuntu, previously copied text returned to the clipboard after each send. Avoid copying on the computer while a sentence arrives, because a copy made while FlowMic pastes can be lost, an effect measured on Windows.
