It sounds like a good idea and it seems interesting but there are two small details in my case:
I haven't had a microphone for a year now. The one I had broke and as I have no reason to use a microphone I don't buy a new one.
English is my third language and I haven't said a single sentence in English (voice) for more than 15 years + I find it very difficult to understand spoken English and to follow a fluent conversation.
If it were something in Spanish it would be obvious that it would be easy to communicate but it is not the case. If everything were written it would also be easy but that is not the case so I see it as very complicated.
I thank you for the offer and appreciate your intentions but it's unlikely to happen, unfortunately.
