…on the dictating machine/dictaphone(?)

on the voice recorder

dictating machine - никогда не слышал, и звучит, как что-то очень большое.
voice recorder - да, добавлю

to dictate/record one’s response ON a dictaphone/dictation machine.

response

Думаю, речь идет о школьном домашнем задании или чем-то похожем, и гугл это подтверждает.

ON🙏

Да, это очень похоже на устный экзамен.

Normally, students don’t use Dictaphone. As far as I know, secretaries, attorneys and translators, use them.  But hey, as long as Google agrees with you! 😉

As far as I know, they normally use voice-recording computer programs during exams in Russia.

"Все дети имеют теперь мобильные телефоны. Можно предложить им при подготовке домашнего задания записать свой ответ на диктофон и устранить имеющиеся недочёты"

ЕГЭ: "Особенное внимание уделили проверке устной части – теперь выпускник должен записать свой ответ на диктофон, после чего запись автоматически отправится ....."

Приложение «Диктофон» превращает iPhone, iPad или Apple Watch в портативное устройство звукозаписи.

A voice recording app would make more sense than a dictaphone. The idea of a student lugging a dictaphone around is actually comical.

lugging around - what does this mean?
Yes, it's unreasonably to expect from every (school) student to have a dictaphone, but it's a very miniature device with much better quality of recording than a smartphone. And you can connect it to a computer and upload the recording to anywhere you want. And it's not very expensive.

Maybe Dictaphone means something different in Russia: https://voxeaglestore.com/dictaphone-2740-standard-cassette-dictation-machine-with-microphone/

Not only in Russia:

However, 'voice recorder' is more common in UK.
And it's a news to me that Dictaphone is a common name - https://en.wikipedia.org/wiki/Dictaphone
Now I know why spellcheckers want to capitalise it.

Yes, it’s a product name and it refers to a rather big piece of equipment. I think they include it in Amazon descriptions so that they can catch people searching for that name. But what you’re showing me in those links is actually what we call a voice recorder. 

I'm surprised that in the 21st century somebody still searches for this expensive 'big piece of equipment'.
I guess those who value its 'foot control'

The pedal is the best part. As a translator, I love them.
