MS Windows 10 and 11 has Voice Typing by pressing the Windows button and H key. A small window comes up where you can dictate your content. This sort-of works on eM Client but it does not capitalize the letters in new sentences and has some other glitches.
I recommend the team at eM Client try to fine tune the use of Windows Voice to Type.
I use it all the time because it allows me to articulate more on my e-mails without the need for typing. Only thing is that then I need to go back and delete the extra spaces before periods, add two spaces after the period and capitalize the letter in the subsequent sentence.
