"It is 7:07."
I am having a hard time with this principal as well. For example: 7 is nana until it is in front of a 'ji'(apparently the character for time-much similar to a digital colon) and time is proceeded by the same number.... It is confusing, I recognize/it reads (to me) as Seven time seven but is pronounced shi-ji nana-fun
I'm doing this on Desktop and the exercise has audio for me when I click through to the discussion page.
It would be a huge improvement I think if there could be playback on the page for the exercise, but this is a site-wide complaint / suggestion / improvement for ALL languages. It seems like something that would be trivially easy for them to add too, like, have a speaker appear after the exercise were completed and allow it to play without requiring people to load the discussion page.
Perhaps submitting a bug report could help? I think if they heard from more people on this issue they might add this.
Numbers like kanji have multiple readings and meanings, i reccomend you use an app called "kanji tree" to learn how to recognise, write and read kanji, including numbers
一 ichi, hitotsu ニ ni, futatsu 三 san, mittsu 四 yon/shi, yottsu 五 go, itsutsu 六 roku, muttsu 七 nana/shichi, nanatsu 八 hachi, yattsu 九 kyuu/ku, kokonotsu 十 jyuu/ju
That's how it should be; Japanese has multiple readings for each character based on Chinese or Japanese (On'yomi and Kun'yomi, respectively). Shichi is the on'yomi and nana is the kun'yomi. They're used in different situations and unfortunately Duolingo doesn't really explain it.
And why DuoLingo needs to add an Audio to speak the final sentence!
It would also be appreciated if the tiles some the correct reading for the exercise at hand!
And then since there are exceptions to pronunciations of certain character combinations, a final Audi for the full sentence is needed!
It doesn't help when both 七 in the answer selections are both pronounced しち
Even though there are multiple ways to mix the pronunciations of 七, having one 七 with the しち sound bite and the other 七 with the なな would at least make the answers you construct consistent with the questions/examples it gives you.
I sometimes find the same problem to be honest. Some modules feel like they really ramp up in difficulty compared to the previous one.
My suggestion if you're struggling is to go back to the previous module in the series (i.e. Time 1) and keep doing that. It does get repetitive, but sometimes working up to level 5 in a module before moving on really helps.
