Using current track variables (%artist, %title) in Text-to-Speech announcements

[eLEn]

Hello,

I am using RadioBOSS 7.2.1.8.

I have successfully configured automatic weather announcements and variables like temperature and humidity work correctly in TTS announcements.

However, I would like to create an automatic announcement of the currently playing song and, if possible, the next song.

For example:

"Dear listeners, you are currently listening to %artist - %title. Next up is %next_artist - %next_title."

I found the Title Format Variables documentation and variables such as:

%artist
%title
%casttitle

but when I use them in a Text-to-Speech announcement, RadioBOSS reads them literally instead of replacing them with actual track information.

My questions:

1. Is it possible to use current track information in a TTS announcement?
2. Are there special variables for TTS announcements?
3. Is there a built-in way to announce the current and next track automatically?
4. Would this require a script or API command instead?

Thank you.
