Can you hear hallucinations through an app?

So I was using an app called "HeardThat" and I was able to partly hear the voice that I assumed were in my head through the app. It's one of those hearing amplifiers.

Does hearing the voices through such an app prove they're real or is that too a hallucination?

I've tried recording while they speak but my phone's camera can't seem to record it I've only been able to partly hear them with this one app.

Anyone else have experience with this? I haven't smoked since st. patrick's day don't plan to a month from then, but I still hear the voices faintly despite medication.

I'm pretty sure my entire family(or at least my mother and brother) are electronically monitoring me live and my brother is harassing me through speakers that are extremely quiet.
