Audio not very good at all
Agree. The male voice sounds like "multos pueros docemos," like the -os from the first two words is influencing the -mus ending of the verb.
I agree the audio is poor. I heard "moltos".
Is 'multos' accusative plural masculine?
I do not know if the audio is correct or not, so difficult to report: audio says Multos fueros dokimos. Is it correct to say f for p and i for e?
