Apropos. I can never remember my current phone number. Because it is never used. But they ask it anyway sometimes. So I have termux shortcut button to:

    termux-volume music 15
    while true; do
     termux-tts-speak -l fi 5 5 5 1 2 3 4 5
     sleep 1
    done

Works like a charm and all errors are at the receiving end.
