Weekly Incubator Update: Tracking Progress from November 6th to November 13th

Several updates from phase 2 courses
It is always nice to hear from the phase 2 courses. These teams work hard to refine their courses with the help of the learning community. The task of going thru the translation suggestions is onerous. This week, we hear from the Hungarian, Ukrainian, and Greek teams.

Yiddish still at 9%, but...
The team has an update for you!

AndrsBrny from Team Hungarian wrote a week ago:


It's been two weeks since the last report, in part because I wanted to see how our day-to-day report handling influences the report rate. A bit erratically, it seems. A bit over a week ago had around 8 reports for a while but then we went back up to around 12. Last week was one of our two most active weeks in the last year though, with around 750 sentences dealt with (and hopefully fixed).

We're obviously continuing to fix as much as we can and with a lot of feedback coming from you we are developing some ideas about future versions of the course and how to improve them!

500K Users!

1 Year, 5 Months, 1 week and four days after Ukrainian for English speakers was released into beta, we have reached 500,000 users! That's like as many people in... well, it's a lot of people!

On behalf of the Ukrainian team on Duolingo, ми дуже дякуємо вам!

We have Audio (TTS)!

Hi everyone!

I'm pleased to inform you that TTS recording was completed and added to our course.
For the next few days we will be reviewing the audio, checking for mispronunciations and things we should disable.
This is the final step before beta!
Thank you for your cooperation.

100K learners

Hey guys!

Wonderful news.

We just reached 100K learners, and that only with the desktop version available.

Thanks everybody for the support.

By the way, the mobile version will be released anytime now, although we have not yet official information.

Greetings from frerejang

Hello! This is frerejang, the newest addition to this exciting project. I briefly introduced myself in the team's chat room, but do consider this a more official introduction. I am a native Korean, so I speak fluent Korean. Like I said in the application, I was educated in English-speaking environment since childhood (since grade 4 to be precise), so I am also proficient in English. Much of this exposure to the English-speaking environment is largely due to my years of stay overseas (Hong Kong, Shanghai, USA) earlier in my life.

Language learning is one of my favorite things in life, and I was eventually led to Duolingo because of this. I started using Duolingo since December 2014 (not too long ago), and first began with German. Gradually I added French and Spanish, and I am now learning (or trying to learn) three languages. Other things I like include watching Association Football (especially the German Bundesliga, thus my interest in German), playing FIFA, walking, climbing stairs, playing PoGo, visiting new places, and eating good food.

Anyways, thank you for the invitation, I feel honored to be part of this amazing project. Korean is not an easy language to teach, and I expect a long and arduous process ahead, but I intend to see this thing through till the end. 잘 부탁드립니다~

Finally Getting Things Going!

After learning how the editor works and a week long trip to Washington, D.C., I finally figured out how to add contributors to the course (as opposed to alpha testers). With my two best Valyrian students, @JustinMans6 and @N.M.C., we're now ready to get the real work going. It'll be a long process, but I'll keep you updated along the way. Rytsas!

mendl from Team Yiddish wrote yesterday:

An update... meshiekhs tsaytn!

Greetings, good people of Duolingo—it's time for an update!

First of all, I would like to apologize for the long lapse in communication prior to the past couple of weeks—our team is much better at teaching Yiddish than we are at PR. (I assure you, that will change going forward.)

The good news is: work on the course has in fact been ongoing! The number on our course progress meter is by no means an accurate depiction of the the percentage of work that remains before the course is ready for beta. This is because we decided to move forward with planning the course offline.

Since I know this is a bit unusual for a Duolingo course, here is a brief explanation of our reasoning:

First of all, in our first attempt at building the course, we essentially tried to go from the ground up, purely on the basis of other Duolingo courses. We realized, after some time, that this approach was not allowing us to produce content that fully utilized our experience teaching Yiddish and creating Yiddish learning materials for various audiences. Since Yiddish is very much in need of high-quality learning materials, we knew we needed to find a way to plan the course so that it would make the best marriage between our practical experience, and the particular strengths of Duolingo's software. This was the pedagogical and methodological challenge.

Secondly, we are constantly astounded and inspired by the incredible diversity of the Yiddish language, and feel that it is imperative to help students of Yiddish become versatile enough in the language to be able to take advantage of all of the many little universes to which it provides unique access. To accomplish this, we needed to construct the course so as to present a balanced version of the language that would allow the student access to as many different types of Yiddish content as possible—written or spoken, leatherbound or online, religious or secular, high-falutin' or informal. This was the sociological and linguistic challenge.

We feel that, in hashing out the outlines of the course over the past few months, we have achieved a balanced approach that will address these needs, and we are happy to say that we are now ready to begin putting this all in place online!

Of course, we will keep you up to date with the latest developments from here on out, and... see you in beta!

El equipo decidió invitar a un nuevo voluntario. ¡Denle una cálida bienvenida a Sahaquiel9102! Él ayudará a combatir la inundación de reportes ;) Además es de Colombia, país que necesitaba representación en este equipo, ya que es un país tan grande y que seguramente traerá buena parte de los estudiantes de este curso.

"our team is much better at teaching Yiddish than we are at PR. (I assure you, that will change going forward.)"

I don't think they should aim for this, though... X-) If one has to choose between those, surely teaching is the more important one?

November 13, 2016

Oh wow. I'm sure they just said that wrong but lol.

November 13, 2016

(Sure, we know what they really meant. :-) )

November 13, 2016

I certainly hope that if the recording begins, that the team will be going for a Yiddish from West Europe accent, since it is where Yiddish is most spoken. Good luck to the team! :D

November 13, 2016

I think you mean Southern Yiddish, as that's the accent most Yiddish people speak. (Polish Yiddish), for example we say "Zugn" or "Zai" but the other Yiddish says "Zagn" and "Zey"

November 13, 2016

It looks like a few courses will be moving to beta soon. I wonder what courses will be added after them.

November 13, 2016

Hopefully less popular languages like Basque, Cherokee, Navajo, Albanian or Serbian (or the other 3 similar to Serbian).

November 13, 2016

Basque and Cherokee are languages I would totally love to learn. When you mention other languages similar to Serbian, are you thinking of Croatian, Bosnian and Montenegrin? I wasn't quite sure what you meant and did some quick research.

November 13, 2016

Yeah, those are all extremely similar.

November 13, 2016

I'm hoping for Arabic.

November 13, 2016

I'm sort of thinking after arabic to spanish, we'll see english to arabic. just a hunch. that team really delivers on courses

November 14, 2016

I would like to see English-to-Arabic added also.

November 20, 2016

Unfortunately, there's no guarantee that some courses moving into beta will mean more languages being added to the Incubator. A year ago this time there were 30 courses in the first phase (and there have been even more at times), so many of those that have graduated since have not exactly been replaced by others.

November 13, 2016

That's true, yet one can always hope.

November 13, 2016

Oh, we're hoping alright! :-)

November 13, 2016

I would like to see more of a focus on languages of Asia and efforts to include indigenous American languages. I feel like they can make more revenue off languages like Japanese or Mandarin or Cantonese, and Duolingo has shown some interest in preserving languages like Cherokee and Navajo (although it's not known if they'll be able to do it.) I also hope the rumors about Arabic for English speakers is true and we'll see it in the incubator by the end of December. Although I would expect at least two more courses either teaching English or adding another option for an existing base language that isn't English.

November 13, 2016

This is the final step before beta

My eyes could really see the final update from the Romanian team!

November 13, 2016

I hope so too - another member of the Romance family in Duolingo!

November 13, 2016

Dang, you're already level 6!!!!

November 16, 2016


November 16, 2016

Haha, now it's 8. :O

November 17, 2016

Welcome frerejang! Nice to work with you! Let's make the Korean course great (again?)!

November 14, 2016

Too soon

November 14, 2016

hey. we've still got the reverse course that we can make great again... am I right guys??? (wink, wink) :)

November 14, 2016


November 18, 2016

I'm glad to hear the Korean course is progressing nicely and thank you for the frequent updates. However, I would strongly encourage you not to reference that hateful and offensive mantra from the Trump campaign, albeit in jest. We should strive not to normalize campaign rhetoric and references that is anathema to millions and millions of Americans.

November 14, 2016

Just joking mate :p. But one also has to consider this has become somewhat of an anti-meme used to poke fun at said candidate

November 14, 2016

There is nothing hateful nor offensive about wanting to make America great again

November 18, 2016

GOOOOOOOOOOOOOO SWAHILI! You can do this! I'll be ready the day it comes to the public, however we do miss you. Please report, we know how much you help others. Thanks! You can do it!

November 13, 2016

I just want to say, congrats to Team Romanian, you guys have come so far, and worked for so long, and this release of the course is going to have to make you guys so proud, because I know that so much work has been put into creating it. Also, I'm glad to know that the Yiddish course contributors haven't given up, as many of us had wondered if that was the case, but in fact were just planning on how to make it even better! It's good to know that we have people like that who are running these courses, that dedicated and hard working. Go Duolingo!!!!

November 13, 2016

Welcome to Team Korean, frerejang! :D

November 14, 2016

I love how Korean's progress has been increasing steadily during the last months. Slowly but surely. Keep it up!

November 14, 2016

Korean did the right thing by putting their release date at something crazy so people don't bug them, but they're seriously moving their course along pretty well.

November 14, 2016

Wow, loads of exciting news this week! Fantastic :D especially excited for the news from Team Romanian and Team Yiddish!

November 14, 2016

Congrats Team Ukrainian for reaching 500K! Excited to be one of the five hundred thousand!

November 14, 2016

can't wait to add to that number once I get the cyrillic alphabet down

November 14, 2016

Just jump right in; the water's fine. :D

Could you be more specific? Really? Only to the quadrillionth? Pfft. Like that tells us anything. And could you update it picosecondly? Plzkthanx. ;D

November 17, 2016

Lol. I'll try to be more specific in the future but I can't say exactly when

November 18, 2016

lol fffffffffffff

November 19, 2016

FYI: Duo just released the RO<-EN course.

November 15, 2016

Thanks for the info! Yeay -- the 66th course is out! :-)

(Soon we'll see if English for Thai comes out within a couple of weeks, or if it beats the current record (979 days), now held by this just published course, of spending the longest time in the alpha stage.)

November 16, 2016

HV seems to be at 1% (and has been for a couple of days so it's not like it changed after the post).

November 13, 2016

That is correct. I use this page to update the stats:

Although for Yiddish, I have to look into the incubator. And I should remind myself that from now on I should look up the incubator for High Valyrian too!

Won't it be nice if Duolingo adds these two course pages so there is one source of truth? :)

Lingots for spotting!

November 14, 2016

Indeed. 1.42% to be exact.

November 14, 2016

How do you check that?

November 14, 2016

Go to the incubator, Right Click on the progress bar and select Inspect Element. The CSS shows the value in % for the width of the progress bar.

November 18, 2016

Not exactly, you can see it upto 17 significant numbers or something like that as DeanG6 demonstrated above. For HV the current number is now 1.5824438307083675%. No userscript needed.
