App comparison
SpeakShark vs Duolingo — different jobs, different tools
Duolingo is the most well-known language app, with breadth across many languages and gamified daily streaks. SpeakShark is single-purpose English speaking. They're complementary more than competitive — but if you specifically want spoken English improvement, they don't compete on equal footing.
Quick verdict
Duolingo is the right pick for vocabulary and grammar foundations, especially if you're learning multiple languages or you're at the absolute beginner level. SpeakShark is the right pick for English speaking specifically — once you can read and write basic English, the bottleneck is usually speaking, and that's exactly what SpeakShark trains.

Where each one actually wins
Where Duolingo leads
- Best-in-class onboarding and gamification — keeps you coming back daily
- Breadth: 40+ languages, so one app for all your language goals
- Excellent for beginners building vocabulary and basic grammar
- Free tier is genuinely usable — you can learn for free with ads
- Strong reading, writing, and listening practice in addition to speaking
Where Duolingo falls short
- Speaking practice is shallow — short prompts, pattern-matching, not open conversation
- Pronunciation feedback exists on Super tier but is not phoneme-level depth
- Designed for breadth, not depth — adults past beginner often plateau
- Gamification can become busywork — daily streak ≠ daily improvement
- AI conversation is gated behind the most expensive tier (Duolingo Max)
Where SpeakShark wins
- Open spoken conversation as the primary mode — real practice, not pattern-matching
- Phoneme-level pronunciation scoring on every utterance
- Four accent targets (American, British, Australian, Canadian) explicitly trained against
- Single-purpose depth: every feature is built for English speaking improvement
- Built by Vietnamese engineers, with phoneme scoring tuned for Asian language speakers
Which one should you pick?
Pick Duolingo if
You're at the absolute beginner level for English (or learning multiple languages), you respond well to gamification and daily streaks, and you mainly need vocabulary and grammar foundations.
Pick SpeakShark if
You can already read and write basic English, the bottleneck is now speaking, and you want deep speaking-specific practice with measurable feedback.
Common questions about this comparison
Should I use Duolingo or SpeakShark?
Use both for different jobs. Duolingo for vocabulary, grammar, and listening foundations — especially if you're a beginner. SpeakShark for speaking improvement — especially once you can read and write basic English but still freeze when speaking. They're not really competing for the same time slot.
Is Duolingo's speaking practice good enough?
For absolute beginners: yes, it gets you started. For adults beyond the beginner stage: usually no. The format is short pattern-matching prompts, which is fundamentally different from open conversation. If your bottleneck is freezing in real spoken English, Duolingo's speaking exercises don't match the real-world task.
Does Duolingo have AI conversation?
Yes, on the Duolingo Max tier (the most expensive plan). It's a meaningful feature, but it's a side feature in a multi-language general app, not the focus. SpeakShark's entire product is built around AI conversation.
Is SpeakShark gamified like Duolingo?
Lightly. SpeakShark tracks daily score trends and progress over time, but it doesn't have the streak-shaming, leaderboard-pushing gamification Duolingo is famous for. The motivation model is more 'measurable improvement' than 'don't break your streak.'
Can I learn other languages on SpeakShark?
No. SpeakShark teaches English only. The UI is available in 19 languages, but the conversation target is always English. If you want multi-language coverage, Duolingo is the obvious choice.
