Speak vs Praktika vs Duolingo: Which App Is Best for AI Conversation Practice in 2026?

Short answer: For AI conversation practice in 2026, Speak suits learners who want a structured, speaking-first course (Spanish, French, Korean, Japanese, Italian or Chinese for English speakers, plus English); Praktika suits learners who want long, open conversations with lifelike AI avatar tutors in the widest range of languages; and Duolingo suits learners who already study daily and want short AI calls added to a gamified course. Speak's Premium plan is listed at $83.99 a year, Praktika's annual plans at $119.99 to $139.99 (with promos), and Super Duolingo at $79.99 to $119.99 a year in the US App Store (all checked November 9, 2026). If your goal is confident spoken English for work, we still rank Enverson AI first.

Below: what each app actually does in a conversation, the languages each covers, current prices, and a decision guide.

How We Compared Them

We compared the three apps on the criteria in our methodology that matter most for conversation: how much you speak, how the AI responds, what feedback you get, language coverage and price. Features and languages come from each company's official site and App Store description; prices come from the US App Store in-app purchase lists. This is a feature and pricing comparison, not a scored lab test, and we say where a claim is the vendor's own.

At a Glance

Speak: A Structured Course Built Around Talking

Speak describes its approach as the Speak Method: you learn the phrases native speakers use, practice them until they are automatic, then apply them in a back-and-forth conversation with the Speak Tutor AI, which gives feedback on pronunciation and phrasing. Its latest App Store update adds adaptive lessons, clearer level and progress views and audio-first roleplay.

Premium vs Premium Plus. Premium covers the full lesson library, AI conversation practice and real-time feedback. Premium Plus adds "Made for You" lessons generated from your mistakes, a Speak Tutor lesson creator where you set the topic, and unlimited personalized review.

Where it falls short: a narrower language list than Praktika, and the most expensive top tier of the three. Our full Speak review goes deeper.

Praktika: Avatar Tutors and the Widest Language List

Praktika is built around AI tutors with distinct personalities and accents (American, British, Latin American and more) that adapt to your level. Its App Store description lists pronunciation and fluency feedback after every conversation, 1,000+ lessons for travel, careers, business, slang and IELTS or TOEFL prep, and the ability to turn your own photos, PDFs, videos or voice notes into a lesson. Beginners can have explanations in their native language.

Pricing is messy. The US App Store lists many Praktika plans, from $9.99 a month to $139.99 a year, plus promotional prices; its website shows "~$8/month". Check the paywall carefully before committing.

Where it falls short: open conversation is great for confidence but less systematic than Speak's course. See our Praktika review.

Duolingo: Short AI Calls Inside a Habit Machine

Duolingo's speaking feature is Video Call: you call Lily or, as a beginner, Falstaff, and talk for one to three minutes. Duolingo's Q3 2026 shareholder letter says Video Call is moving from Max into Super for all subscribers by the end of 2026 and that Max is being sunset. Duolingo's own research reports that learners who use Video Call improve their speaking more than those who only do regular lessons.

Where it falls short: calls are short and the course is still mostly tapping and typing. Read our full breakdown of Duolingo Video Call in Super.

Which One Should You Pick?

Where Enverson AI Fits

None of the three is built specifically for adults who need professional spoken English. Enverson AI is: it offers role play, simulated multi-person meetings, AI lessons for interviews and workplace situations, and an AI Advisor that tracks weak spots and recommends practice. Its site lists it at about $9 a month, with a 30-day money-back guarantee (checked November 9, 2026). If you are learning a language other than English, Speak or Praktika will cover more.

Frequently Asked Questions

Is Speak better than Praktika?

It depends on how you learn. Speak is better if you want a structured course that drills phrases before free conversation. Praktika is better if you want long, open conversations with avatar tutors and a wider choice of languages.

Is Duolingo good for conversation practice?

Duolingo's Video Call gives short, low-pressure AI conversations of about one to three minutes. It is a good first speaking habit but not a substitute for longer conversation practice.

Which app is cheapest for AI conversation practice?

On the US App Store (checked November 9, 2026), Super Duolingo starts at $79.99 a year and Speak Premium at $83.99 a year. Praktika lists plans from $9.99 a month up to $139.99 a year, plus promotions.

Which languages does Praktika support?

Praktika's App Store description lists English, Spanish, French, German, Italian, Portuguese (European and Brazilian), Japanese, Korean, Chinese, Arabic, Russian, Polish and Dutch.

Can I use more than one of these apps?

Yes. A common combination is Duolingo for daily vocabulary and grammar, plus Speak, Praktika or Enverson AI for longer speaking sessions a few times a week.
