Hello Keith -
These are just software programs or apps that use sound, words or voice fragments in their sound banks. These sounds come through the programs but in no order. Since I do not program software or apps, I have to use those that are made by others. There is a leap of faith as far as what they say is in the sound banks and what actually might be there. For example I have found quite a few programs that do have short sentences and words in their sound banks but these sentences are supposed to be broken up via the program. In some cases the words are even suppose to be in reverse speech.
I have worked with one of Martin Bellefeuille's early programs called the VR Ghostbox since 2017. By working with it that long I figured out what was normal in the program and could hear when something unusual came through. While results, that I might consider paranormal in nature, don't come through all the time, I did notice that when they did come through it was in packets or groups. What I mean by this is that during a session there may be many minutes of nothing understandable or relevant coming through but then I would get several minutes of voices that talked in long sentences or answered direct questions.
I do have some interesting examples from the VR Ghostbox on the YouTube channel of my paranormal investigation team, the Society for Anomalous Studies. The ones of interest are in the Playlist under a heading called Sustained Electronic Spirit Communication. I wrote an article about the VR Ghostbox sessions for a book that features woman in the paranormal and that YouTube playlist is examples I talk about in the chapter I wrote. I'm not trying to promote my team or writing here but rather wanted to point you towards what I have been working on.
As a side note this year my team went through a big shake up and half of the group left. We ended up bringing some new people into the team and when we did that our results with the VR Ghostbox declined. Things have not returned to what we were recording as recently as 2020 but I think things are starting to jell again. That itself is a very interesting topic for another thread.
