Searching for the earliest sound recordings from Slovak Republic

Dear Madam/Sir,

I am searching for the earliest sound recordings from the area that is now Slovak Republic.

Are there any Slovak institutions in your Association? Or can you maybe point me to other sources where I could possibly access them?

I can explain in more detail if necessary.

Thank you very much.
Best wishes,

Dusan Barok
