Maybe after the bell, you might want text to speech to announce periods or special events or emergency procedures.

You will likely need two approaches

• Structured : Series of templated text messages with %VARIABLE% representing 'period number' or 'day' or 'event name' etc...
• Unstructured/Freeform : Straight TTS of text for full control

Being that this is a wall powered device, you don't really need to worry about energy efficiency, but you may want to render the audio ahead of time and spend extra cpu cycles to make sure the audio quality is very clear

You may also want to consider having two different options:

• Relay output to control external mechanical bells (if it's a retrofit)
• Relay output to control dedicated 'visual bell' alarms for deaf students to see

Schools for the hearing impaired use alternative signaling methods, for example sign language from the teacher and lights that illuminate when the public address/bell is sounding.[3]

After rebooting my Raspberry Pi 4, the uptime in the Web Interface showed as 3 days when it should read only a few minutes. Will need to look into this issue. Pasting log file below:

Also note that succesful should be spelled successful. This issue needs to be fixed.
