[LAU] Accessibility: Peak indication (OT?)

Friends I am working on a recorder that priorities simple keyboard control, it has very little gui. This is what I need, but one important use is for people who cannot look at a gui (me, I cannot be bothered, I find GUI displays usually very distracting, and at best inconvenient) I do want to have peak indicator, a warning if the level is too high and data loss is occurring. This is a new journey for me, and some concepts might be a bit fuzzy in my head, forgive me. How can I have a warnings in my software that will play nice with accessibility software? Should I output lines on stdout that screen readers can process and then do whatever they are configured for? I want to get this right from the very start. I though this might be a good place to ask I am sorry if this is a bit off topic for Linux audio Sent from [Proton Mail](https://proton.me/mail/home) for Android.
