A video demonstration of creating a Joplin To-Do with an alarm that triggers a notification at 17:00 hours. Voluble then reads it outloud.
Please, note the extension icon in the top bar. The appearing microphone icon indicates speech input (I am dictating the text into Joplin using BlahST.)
Please, enable the sound and use full screen mode to see the details (the to-do alarm triggers at around 1:06 min):
