I can hear it! It kind of sounds like someone got a microphone and recorded it in a house that was just emptied for moving. Not that it's bad. It's clear and it works.
Other courses use TTS. This (and Irish, and maybe some more) has the real person to record the phrases
Which is still funny. The artificial language is one of the few with a natural voice.
Technically it's wrong (if you are a grammar nazi :) ), but recently we are using it less and less, perhaps because of all the USSR work on diminishing Ukrainian, or perhaps because there are just so many cases already! Similar to Germans using less and less Genetiv and often replacing it with Dativ
Кличний відмінок ніхто не відміняв і менше не стали його використовувати. Правильною формою тут буде саме "тату", а не "тато".
Так, звісно, ніхто не "відміняв", але сучасна молодь вживає його менше і менше, як я написала, можливо через совіцький вплив. Я завжди кажу "тату" та "мамо", але доволі рідко вживаю з іменами ("Маріє", "Олеже")
Audio is pretty clear here. Check your settings, maybe? If you are studying from your mobile device on a mobile version - this happens. Several people reported that. Desktop version works better.
Can you accept "Yes, it is dad" as a translation ? Someone having a conversation with dad would reply (to a yes or no question) , так тату. However, if the question is something like "Who is downstairs, is it dad?", then the answer should be так тато. Does this make sense?
I have done this before using the app on my phone but I have to say I enjoy this a lot better on my PC. I find it so relaxing
