When transcribing, you should not use symbol characters, for example, if an audio says:
Last week 50% of the payment was completed, which equals $ 200.
It would be correct to transcribe:
Last week 50 percent of the payment was completed, which is equal to 200 dollars.
It would be wrong to transcribe:
Last week 50% of the payment was completed, which equals $ 200.
Another example:
I sent it to the email you sent me, I'll repeat it: nicolas@gmail.com
It would be correct to transcribe:
I sent it to the email you sent me, I'll repeat it: Nicolas at Gmail com
It would be wrong to transcribe:
I sent it to the email you sent me, I'll repeat it: nicolas@gmail.com
