Although many claimed the credit, the first voice heard on the radio belonged to Reginald Fessendens. In 1906 Fessendens a physicist born in Canada spoke from Massachusetts to ships offshore. Generally speaking radio communication was most useful in rescues. The "wireless" was used for ship-to-shore messages.

You also do not need a comma behind a certain date. (hint 1888)

Not quite yet. you still need one behind 1906; Generally speaking (rescuses is spelled incorrectly); began

so, put one behind

1906
Generally speaking
began

Correct your spelling typo and you should be good to go.
