Auditory Processing Disorder is a common part of Autism. I only speak 1 language, but frequently have difficulty understanding speech. Sometimes it can be more than 5 seconds after some has spoken that I start understanding what they just said. If I’m familiar with the person (e.g. family) it’s much easier to understand.
I have been told that Auditory Processing Disorder can be treated with speech therapy, but it hasn’t been important enough to me to try, so I can’t give any personal opinion on that.
I had a basic terminal app 10 years ago that was built better than that. It could barely do anything without root access, but at least it want a web app.
