The Sumerian language is a language isolate, how did they possibly figure out how to read Sumerian and how did they learn the phonetic sounds that go with the language?

I saw a documentary about Sumer. During it, they showed someone reading a clay tablet out loud in Sumerian. How could that possibly know the sounds of the letters?

There's always more to be said on the topic, but I discussed the discovery and decipherment of Sumerian in When did the modern understanding of the history of Bronze Age Mesopotamia develop?
