Clipped audio

Konnichiha, minna-san !

I'm a new Japanese Duolingo user. I've been practicing Mandarin Chinese on Duolingo with my phone for months now. For Japanese, I've switched to my computer as an experiment (phone is very old). Turns out practically all audios are clipped (Japanese and Chinese alike ; no clipped audios on phone). Does anyone else have this problem ? Even with the new voices it still happens. It doesn't matter whether I change browsers (main browser = Firefox -> tried on Chrome -> still clipped audio). The audio clips toward the end of the sound so it's not too bothersome when dealing with sentences. It becomes very annoying when learning new Hiragana characters (and other single syllable words) though, as almost 100% of the audio is clipped.

Is there something I can do to fix this ?

Thank you, all !

I've done some research on this myself, actually. Here are some things I've noticed about audio clipping for me:

  1. Audio is more likely to clip the longer I leave the logged-in tab open. Also more likely the longer I go without restarting my computer.

  2. Audio is loaded every time you start the next question in a lesson. In other words, it loads the audio on the spot. From what I've heard it's not so with the mobile version, but I don't use it so I wouldn't know. The loading-as-needed system means that more internet speed is needed.

  3. Usually (but not always) clicking on the speaker icon to have it repeat the clipped audio will play it back normally, since it's now had a moment to load.

  1. There does seem to be a delayed as I have to press the speaker icon multiple times to hear the majority of the audio file.

  2. I haven't noticed an improvement of the audio after restarting my pc in past. I'll do it later on and pay attention to see if it changes something.

So, your explanation is the best yet I've seen for this problem! As such, I've referenced it in another post in the troubleshooting forum (and provided a congratulatory lingot ;) );

Any further movement? It looks like a web developer thought this would be a good idea, but the UX department (User experience) didn't get a look in! Easily done - I'm a software developer!!

I have never encountered this issue but I suspect it could be an internet connection issue. If you are using WiFi try hard wiring into your internet and see if that makes a difference. Additionally, have you tried clearing the browser history including the cookies? (Make sure you have logins somewhere accessible outside your browser before you try that)

Hello, Thanks for the reply. (+ 1 lingot :p)

Do you mean using an ethernet port by hard wiring ? Unfortunately my laptop has no such port.

About the cookies, I recently cleared them but it had no effect on the audios either.

Yeah, it's a wi-fi speed thing. If you have a slower connection speed, it'll take longer to load the audio clips.

Clearing cookies shouldn't make a difference, but it's true that your browser could run out of memory space. It can hold a lot though, so just have it cleaned once in a while and you should be good.

If in doubt about the audio, you can try to double check it here:

Amusingly I've found the best browser for this problem is old IE 11. If it is an audio loading problem a slow browser seems to mitigate the problem somewhat by slowly loading the page.

This would probably be better in the Troubleshooting forum since it isn't language-related.

I've noticed it clips pretty often on Firefox on my Windows 10 desktop computer. But I've never had it clip on my ancient Windows 7 wireless laptop with the old Firefox. (Note these are in two different towns though so they're not running on the same connection). I'm not sure what causes the clipping but it's possible it is an internet issue. My desktop at home that is hardwired tends to load slower than my old laptop on wifi, but it also tends to load slower and freeze up more often in general even when not using the internet so that isn't much to go on.

Is there some way to move the discussion to the Troubleshooting forum ? Or should I start a new discussion there ?

I was actually thinking of trying Duolingo on another computer to see how the audio fares but I've not been able to get my hands on one for the time being.

If you edit your original post you can change the forum. There'll be a green button at the top that says "Topic: Japanese" you can click on to get a dropdown menu.

I have the same problem and it is very annoying!
