Vietnamese keyboard setup

Hi all,

I will show you how to set up Vietnamese keyboard on your computer.Although there is on-screen Vietnamese keyboard to install, my recommendation is to learn typing Vietnamese because it is more efficient and can actually help you learn the language! In general, there are two main input method: TELEX and VNI. This instruction will go with TELEX (recommended for new learners).

For Mac OS

Mac OS has a built-in Vietnamese keyboard already. You only need to go to System Preferences, choose Keyboard, then choose tab Input Sources. Click the plus icon (+), choose the language (Vietnamese) and select input method as Simple Telex (Telex is fine, there is no difference).

It should look like this:

Next, you must tick the box that say Use modern orthography as shown in this screenshot:

The only difference between traditional and modern orthography is that the tonal mark in modern orthography is placed on the second vowel in a diphthong (oà, oè, oẻ, oá, oả…) while it is placed on the first vowel (òa, òe, ỏe, óa, ỏa…).

Duolingo answer database will base on the modern orthography so if you use the traditional one, you will get an unnecessary typo notification.

To change your keyboard back to English, click on Telex at the top right corner of your screen and choose English.

For Windows OS

You may need to use a third-party software to type Vietnamese. It is called Unikey and can be downloaded for free at Note that this program is virus-free and has been used by majority of Vietnamese for years.

Go to and choose Download on the left side. Under UniKey 4.2 RC4 (this is the latest version), you will need to choose either 32 bit or 64 bit version. Windows 10 is also supported.

You will download a ZIP file. After extracting the file, run the exe file. A control menu will appear but in Vietnamese interface. Click on Mở rộng as shown in this screenshot:

Then, un-tick the Vietnamese interface box. Your interface will turn to English.

Finally, tick Use oà, uỳ box to use modern orthography as I mentioned above.

Click close. You can always check it at the bottom right corner to see if it shows E (English) or V (Vietnamese). You can type Vietnamese when it shows V. Click on it to switch between Vietnamese and English.

Note: Windows 10 and 8.1 do have built-in Vietnamese keyboard and you just need to download the language pack from Microsoft. However, they are likely to have VNI input method only and very limited options. If there is a demand for VNI input method, I will post a separate instruction later. Additionally, I cannot confirm if Windows 8, 7 or earlier have built-in Vietnamese keyboard. The easiest way is to use Unikey.

Manic Monday

Hello, hello,

it's Monday (wish it were Sunday?), sorry about that. And for a couple of days I thought this was going to be a blue Monday, as we've been struggling to figure out how to plug the holes I was talking about in the previous update. After a good start, it turned out that my first approach didn't quite achieve what it should have.

But since, Ferenc (woolfool) figured out how to do it — so now, we're back to swift progress! This should soon be reflected in the predicted completion date, too. What happened was that when moving some skills, I duplicated a few words, thinking that I could easily remove them once the new skills were done. It turned out that it wasn't quite that simple.. but now we know how to do it and I've (re)moved three lessons worth of words — these won't push the completion date further back.

In other news, nearing beta, we're going to take on two new contributors to the team! We are receiving many, many applications and I'm very sorry to say that we probably won't be able to contact everyone who does apply (at least right away). Thanks to everyone who shows interest and is keen to help — there'll be plenty to do during beta. I'll keep you updated on when our team is growing!

Summary (tl;dr)

After some confusion about how to fix the holes I created, woolfool figured out a way to do it, so the scary completion date should normalise soon. We're also going to add two contributors to the team, and we're looking at applications! As usual, thanks to everyone and have a good week!

Typing Vietnamese guide


Here is how to type Vietnamese character with TELEX input method. If you have not set up a Vietnamese keyboard with TELEX on your computer, please refer to my previous post.

Make sure your Vietnamese keyboard is active. When done, make sure you deactivate the keyboard or it will mess up your typing in other languages badly.

In general, with Telex input method, users are required to type in a base letter (a, e, i, o, u, d) or diphthong or triphthong, then type in a corresponding letter to add tonal marks to that base letter.

How to type special Vietnamese vowels

Here is the table showing how to type special vowels (đ is not a vowel).

How to type tonal marks

The following table shows you how to add tonal marks to the base letter.

Complete set

As you combine both methods above, you can easily add tonal marks to either regular or special vowels. Here are some examples:

All diphthongs and triphthongs could be typed and added tonal marks in the same way since they all have vowel(s) as a base letter. As long as you activate modern orthography, the keyboard will automatically placed tonal marks above the second vowel.

Note: You must activate modern orthography typing mode from your Vietnamese keyboard or else you will receive typo notification. For more information about this issue, please check my previous post.

It may take one or two weeks for you to get used to these typings. As long as you are familiar with typing Vietnamese, you will learn Vietnamese much faster.

Course Update

Breaths of life! As I predicted, the progress of our course slowed significantly in the past month. It has been a very busy time here at Peace Corps Tanzania with the end of the most recent training arriving this past week. You can check out some of the updates about what's been going on here at Peace Corps Tanzania's Facebook. We recently swore in 43 new Volunteers.

This update's Swahili proverb is indicative of what's been going on. Literally, it means the vessel does not go but without a roller. Essentially, progress cannot be made without someone driving that progress, and since all three of the core team members have been busy working with the training in rural Tanzania, our ability to drive course development has been hindered lately. But, we're back! Right now, I'm working on restructuring a lot of basic elements of the course based on the last few updates and some of the Incubator changes. I wasn't able to do as much of this as I wanted before I joined Mama Rehema and Emilian in the field, but I'll be working on that in the coming month so that we can really hit the ground running with the rest of the course. We anticipated that this would be a small road bump before being able to make fast work of the rest of it, but I believe that once we nail down how we're structuring all of our exercises, the process of course creation will be a lot easier.

Our Alpha Testers have been doing a good job testing the elements of the course that do exist, so we're also going to be working on making those necessary changes while the restructuring goes on. We apologize for the silence in the past few weeks and continue to be thankful and appreciative of the support and enthusiasm we've been getting for the course. We really look forward to delivering a quality course that really helps teach functional and useful Swahili!

Al compartirlo en redes sociales seguro que sorprenderá a más de un amigo y podrá animarles a aprender esperanto contigo. El vídeo es una entrevista corta a algunos nativos de esperanto.

And EnricBaltasar from Team EO for ES further added 5 hours ago:

Soy Enric, y ahora tengo superpoderes en Duolingo

Saluton! Soy Enric Baltasar, un joven idealista de Valencia (España) que un día se dio cuenta de la necesidad de una lengua internacional justa y decidió crear un nuevo idioma. Descubrir luego el esperanto fue un hecho previsible, pero jamás me hubiera imaginado cuánto aquello cambiaría mi vida.

He estudiado informática y ahora estoy con marketing, pero no me atrevería a definir mis intereses de esta manera. Me considero un autodidacta con una curiosidad insaciable por prácticamente cualquier tema, y por ejemplo llevo años asistiendo a clases universitarias de un montón de grados diferentes: psicología, filología, ciencias políticas, sociología, etc.

Soy un apasionado de los movimientos sociales, tanto a nivel práctico como teórico. Mi aventura con el esperanto me ha llevado a hacer de todo: enseñar el idioma, organizar encuentros, dar charlas, escribir poesía, formar a activistas, fundar organizaciones y más. He sido activista a nivel local, regional, nacional e internacional. Ahora mismo soy el Comisionado Europeo de Acción Territorial en TEJO, la organización mundial de jóvenes, y he sido elegido por el Foro Europeo de la Juventud como líder nacional y experto en movimientos sociales.

¿Qué más? Podrías conocerme desde hace años y aun así no adivinarías qué es lo siguiente que voy a hacer. Soy políglota (5 idiomas), viajar a nuevos países es una de mis aficiones (por suerte cojo un avión cada cuarenta días), me encanta trabajar en equipo y una de las cosas que más me motivan es que me propongan proyectos para los que no estoy preparado.

GunnyTunes from Team DE for AR wrote after the bell:

Our course is now on the mobile apps!

Hello everyone, we're glad to announce that our course has reached its second milestone, and that is getting on the mobile apps!

Next milestone would be getting out of beta, then of course updated tree versions!

If you happen to know any Arabic speakers wanting to learn German, please guide them to the app!

And now in Arabic:

Thanks very much, All of them are wonderful, thanks you very much, here you are 2 lingots for my appreciate and you appreciate more than that of course. :)

April 24, 2016

I see Finnish in there, so a lingot for you!

April 25, 2016

And of course, a lingot for you as well!

April 26, 2016

Ahh if they make Croatian, Serbian or Bosnian course (or all three since they are pretty much like British and American English), I'd LOVE to contribute!

From the Hungarian Facebook page:

"Hey everyone. Sorry for only one update this week — busy times. I can report some good news, however. All the holes are plugged, all the words have sentences, all the skills light up in beautiful gold in our course tree. From what I've been told over the last weeks, we've done everything we had and wanted to before going into beta, so we'll try and make it happen with help from duolingo! Thanks once again for all our patience and I hope you won't have to wait much longer!"

April 24, 2016

If I'm understanding it correctly, it's now only matter of duo team doing their prep work?

April 25, 2016



Now all of a sudden the Turkish, Polish, Esperanto, Norwegian, Russian, Vietnamese, and Ukrainian courses have come out

And now all of a sudden there are courses for Welsh, Hindi, Hebrew, Korean (dang it!!), Czech, Indonesian, Greek, and Swahili, as well as a Guarani for Spanish and so many other great courses that I haven't paid attention to because they don't apply to me as an English speaker (sorry, I know you deserve attention too, courses that don't apply to me as an English speaker, and I know your contributors worked hard on making you)!!! Duolingo has been busy and booming!!!!!



April 24, 2016

Guessing through the courses that you've mentioned, have you been gone for at least one year?

April 25, 2016

It certainly doesn't feel like it ;)

April 26, 2016


April 25, 2016

I can't wait for all those languages, especially for Czech and Hebrew!

When a new language will be added to the Incubator?

April 24, 2016

That's what I keep wondering. What's the next language? Not knowing just makes it more exciting.

April 24, 2016

Finnish! It really wouldn't surprised me if it finally is Finnish. I read somewhere (I don't remember where) that they were planning on adding Finnish this year, and this seems like a particularly good time. :-)

April 25, 2016

Alfmf! A lingot for mentioning Finnish! Let's go! (Why am I always the one to start this, anyway?!) :)

April 25, 2016

You aren't. You haven't been paying close enough attention. :-P

April 25, 2016

I don't remember anyone saying anything like that, but I wish it was true!

April 25, 2016

I seem to remember it being in an interview with Luis. I'll go looking and see if I can find it. :-)

April 25, 2016

Or 124 someones. :-)

April 25, 2016

Well there's someone hoping you find it! :D

April 25, 2016

Agreed! Especially with Hungarian on the brink of Beta. I'm studying both right now at home and one skill set definitely lends to the other.

April 25, 2016

Yay! We haven't heard from Swahili in a while. Just to note, the estimated completion date is August 1 now, not July 1 any longer.

April 24, 2016

Good catch! I will update the date.

April 25, 2016

Hey jitengore! When will we have some new courses in the incubator?!

April 27, 2016

Unfortunately, I do not know! Duolingo makes that call based on several factors as one can imagine.

May 1, 2016

Can't wait for Greek next month!

April 24, 2016

More like in two weeks or so. I hope it will reach beta before my trip to Greece (1st of June)

April 24, 2016

Unfortunately for us, one of the Greek contributors said there might be a slight delay. I'm waiting impatiently for the course as well.

April 24, 2016

I'm going to Athens at the end of June, and I plan on visiting some Greek Islands this summer while living in Turkey. So I really hope the Greek course hatches on time.

April 25, 2016

If you're interested in Greek, check out the (free) Language Transfer course :)

April 25, 2016

I love you Czech team ! You keep your fans updated weekly and make steady progress. I will definitively try your course when it will be available

April 24, 2016

And now it seems that they'll even be the Leader Extraordinaire regarding the pace of all the other teams :-P

April 25, 2016

Haha yeah. With 6 courses at 100% the mean is going to be very low. Although Romanian can still be a leader one last time :)

April 25, 2016

Or if the Hungarian graduates this week, than they will be the Leaving Leader Extraordinaire ;-)

April 25, 2016

Folks, stating what is now obvious! Today's WIU is running late by a few hours. Please stay tuned!

May 1, 2016

Awesome! I really want to try Esperanto for Spanish! :D

April 24, 2016

Y yo quiero aprender Español de Esperanto!

April 25, 2016

While waiting for your next course, why not try Vietnamese? It is very challenging and a load of fun. ckhadung's keyboard instructions are spot on. The course is off and running and at least one person has already completed the tree!

Now I'm waiting for Hindi & Swahili, while learning Vietnamese and keeping French and Spanish sharp, whew!

Merci, gracias, vè cảm ơn jitengore for the great updates.

April 24, 2016

News from the Hungarian team that has me pleased.

A shiny golden tree...

Hey everyone,

our tree just lit up all golden again. We've fixed all the holes and since we've finished adding all the new sentences to our new skills a week ago, this is it. We don't need to add any words or sentences for beta, and we won't add any new skills or mess with the tree now either!

We'll compile a list of sentences we would still like audio recordings for and continue to add translations to our sentences missing them, but to the best of my knowledge there is now nothing stopping us from going into beta and I'll try and get us there as soon as possible — you'll get an update about that!

With any luck, I'll have that Hungarian flag by my name in 2-3 days :)))

April 25, 2016

I'd say longer than 2-3 days especially if they have to wait for a few more recordings but yes!!! So excited XD

April 25, 2016
  • 1391

The wait is never over for us who follow the WIU! I'm so happy for VN to be out in beta, but I'm waiting for Guarani next :-) and in the long run, for Romanian and Czech.... Go Guarani go!

April 24, 2016

What about Greek? Just not into it?

April 25, 2016
  • 1391

Not really... neither Hebrew... I might dabble a bit in them but I don't really have a motivation to learn them seriously. There are so many languages coming up, it will be hard for me to focus on those I personally want to learn, for some reason or other.

April 25, 2016

Cool. Yeah, it's great to focus 4sho.

April 26, 2016

I am really looking forward to being able to learn Hebrew! :)

April 24, 2016

Yay! French for Chinese made progress!(Although I doubt I'll ever take the course)

April 24, 2016

Probably the second most notable news this week.

April 24, 2016

And now it broke the incubator(kidding, of course) with progress. Maybe I will take the course and until I get my tablet fixed so I can install ChineseSkill the struggle will be real. #WhatIJustSaid

April 26, 2016

I am so happy to see a Swahili update! I can't wait for that course.

Also, gyah, I can generally only handle two new languages at once but Hebrew is almost done! Then again I'm still torn on whether to go for Yiddish or Hebrew. There are some really amazing books in Yiddish, especially from the mid 1900's. Hebrew is more commonly spoken in the world, but Yiddish is still more common than Hebrew in the US. Although both are rather rare. Decisions, decisions. At least I have a bit of time before Hindi finishes. Otherwise I'd be buried. Too many amazing languages! It's like an all-you-can-learn buffet. :D

April 25, 2016

[deactivated user]

    Really looking forward to Greek, Hindi and Korean. Big thanks to all contributors!

    April 25, 2016

    GunnyTunes from the German for Arabic team has a newly added update regarding their course availability on the mobile apps. Please revisit to read the English and the Arabic versions of the notice.

    April 25, 2016

    I am waiting!!!!

    April 24, 2016

    So glad that Vietnamese is out! I've been making slow progress but I've enjoyed every second of it. I'm also especially lucky to live someplace where there is a strong Vietnamese presence and can ask some of my friends to help me with pronunciation. Though I do have to say I'll only be going up to around level 7 before returning to finishing my Esperanto tree, I will absolutely return to Vietnamese as soon as I do.

    One thing I have to ask, if there's anyone out there that can provide an answer, is why is Telex such a preferred layout? If VNI is the one that replaces your number row with the letters and tonal marks and uses RightAlt + these keys to use said numbers (I'm using Google Input Tools and the keyboard I use is called TCVN 6064), then I have to say I find it easier and more intuitive. Well, in the end a preference is a preference and it matters little which people use.

    Oh, and good to hear from Team Swahili. While I pretty much look forward to any course that comes out, I have to say I'm as excited for Swahili as I was for Vietnamese.

    April 24, 2016

    I would not say Telex is a preferred input method for everyone. It really depends. However, using Telex is more efficient than others because your fingers don't have to reach out for number keys or alt key then press another key to add tonal mark to base letter. This would make more sense when you type with smartphone keyboard. Then again, it still depends on individual preference.

    April 24, 2016

    Ah, that makes sense. If efficiency is what one's after, Telex definitely makes more sense. I just found the other one easier to get used to. It only took a few days rather than the couple weeks suggested above, but as you said, it depends on the individual. Thank you for the reply!

    April 24, 2016

    No news about an updated version of the Turkish tree?

    April 25, 2016

    Keep going Klingon! Can't wait for August!
