The people copying code off the air were mainly trained that a particular sound required that you type a particular key. The traffic was all encrypted. The cypher text was passed off to others for decryption.
The US Navy trained Filipina natives who did not speak English to copy Morse by ear on typewriters. Cypher text was 5 character code groups. A lot of routine Pacific Fleet traffic went that route. The decryption was done by military personnel with clearances.
