Speak vs Duolingo: which is better for speaking English, and how to decide in 20 minutes

The short answer

Choose by the goal, not by the brand.

This comparison uses what each company says about its own product, on its website and its App Store page, plus a third-party comparison for the language count. It does not rank the apps by price. Prices differ by country, change often and include trials, so check the current price on the App Store or the company's own page before you decide.

YoFluent, which publishes this blog, is also an AI speaking-practice app. It is not part of this comparison, and the advice below applies whichever app you choose.

How Speak says it works

Speak's App Store page says its key difference is getting you speaking out loud from day one. It lists English, Spanish, French, Italian, Japanese and Korean as languages you can start speaking in the app.

The company's own website describes the Speak Method as a loop in three steps:

1. Learn the phrases native speakers use.
2. Practise them until they feel natural.
3. Apply them in real conversation.

The website also says you repeat the same patterns in new situations, again and again. The App Store page adds that AI technology lets you practise real-life conversations and get instant feedback.

What this means for you: the app is organised around saying sentences, not around reading or matching words. Every lesson ends with you speaking. That suits a learner whose problem is I know the words but I freeze when I speak.

Things to check for yourself: how detailed the feedback is on your pronunciation, whether it corrects grammar as you speak, and whether the conversations feel like real life or like a script.

How Duolingo works

Duolingo is known for short lessons that feel like a game: you earn points, keep a daily streak and move up levels. A third-party comparison reports that Duolingo says its free app teaches more than 40 languages.

The strengths are easy to see:

• Habit. Five minutes a day is enough to keep the streak going.
• Range. If you also want to learn another language, one app covers both.
• Low risk. You can try the free version before you decide anything.

The weaker points for a speaker are also clear from the format. Lessons rely heavily on tapping, matching and typing, with some speaking exercises. A learner can finish many lessons and still not have spoken for ten minutes in a row. That is not a fault of the app; it is what the format does.

For open conversation, you need to add something: a speaking partner, a tutor or an AI speaking app. For ideas, see free English speaking apps, which explains what free plans really give you.

Side by side: what matters for speaking

Two cautions about tables like this. First, apps change often: features move between plans and new ones appear. Second, "has conversation practice" does not tell you how good it is. Quality depends on how well the app hears your voice and how specific its feedback is.

That is why a test on your own phone beats any comparison page, including this one. The next section shows how to run one.

A 20-minute test you can run yourself

Do this once with each app. Use the same level and the same topic, such as ordering food or introducing yourself.

1. Minutes 1 to 5: do a normal lesson. Notice how many times you actually speak, not tap.
2. Minutes 6 to 10: say a sentence badly on purpose. Use a wrong word or a wrong stress. Does the app notice? Does it tell you what was wrong?
3. Minutes 11 to 15: try a conversation. Can you say what you want, or does the app only accept one answer?
4. Minutes 16 to 20: read the feedback. Is it specific (you said "ship" instead of "sheep") or general (good job)?

Score each app out of five on three questions: Did I speak a lot? Was the feedback specific? Would I come back tomorrow? The best app for you is the one with the higher total, not the one with the bigger name.

If you want to check your own stress and rhythm after the test, the guides on word stress and English intonation explain what good feedback should mention.

Using both, and what is still missing

Many learners get the best result by combining tools, because they do different jobs.

• Duolingo for the habit. Five minutes a day keeps English in your life, even on busy days.
• Speak for the speaking. Use it two or three times a week for a longer spoken session.
• A real person for the unpredictable part. A friend, tutor or language partner will interrupt, change the topic and speak unclearly, which no app copies perfectly.

A weekly plan could look like this:

The goal of the plan is simple: speak more, get feedback and repeat. If you want a full daily plan, see English speaking practice.

Mistakes learners make when choosing

• Choosing by the streak. A 300-day streak does not mean you can hold a conversation. Count the minutes you spoke, not the days you opened the app.
• Staying in the comfort zone. If every answer is a tap, you are practising recognition, not speech.
• Never recording yourself. Listen to one minute of your voice each week. It is uncomfortable and very useful.
• Expecting an app to replace a real conversation. Apps build confidence and accuracy. People test them.
• Paying before testing. Use the free version or trial first, and cancel in time if it does not suit you. Read the trial terms in the App Store before you start.

The point of all of this is to choose the tool that makes you speak the most. Everything else is a detail.
