Since then, I’ve been looking for a simpler way. I ended up using Audacity to record the computers audio. I liked the voices but it doesn’t have an option to save the audio as an MP3 file. When I did those, I used to convert text to speech. One in a clock that plays announcements and the other a countdown timer.
I’ve made a couple of projects that play audio alerts using a dfplayer and MP3 files.
