Its Speak Method loops through three stages — learn the phrases native speakers actually use, practice them until they become automatic, and apply them in real conversation with the AI Speak Tutor, which returns immediate feedback on your pronunciation and phrasing. The curriculum is created by language education experts and personalized by AI, with lessons matched to your level. **Preços e planos:** Free trial plus subscription. Speak offers a 7-day free trial; afterwards a paid plan is required. Two tiers exist — Speak Premium for the core experience and Speak Premium Plus for unlimited personalized lessons, custom review from your mistakes, Made for You lessons and the full tutor experience. Prices vary by plan, region and promotion and are displayed in the app. - **AI conversation practice:** The Speak Tutor holds a real back-and-forth conversation with you in the target language and gives feedback on what actually matters, as many times as you want. - **Real-time pronunciation feedback:** Speak flags pronunciation and phrasing problems as you speak, so you can correct habits before they set in. - **Phrases-first curriculum:** Every lesson is built around the phrases and patterns native speakers use in real situations, avoiding textbook sentences and grammar drills. - **Personalized lesson paths:** The app adapts lesson order and content to your level and goals, with Premium Plus adding Made for You lessons and review built from your own mistakes. - **Learn on your own schedule:** Lessons and tutor practice work on a phone, so a session fits into a commute or a coffee break rather than needing a scheduled class. **Pontos fortes:** Built around speaking from day one instead of vocabulary drill and grammar exercises; Immediate AI feedback on pronunciation and phrasing without the pressure of talking to another person; Curriculum designed by language education experts and personalized by AI; Backed by OpenAI via a formal partnership and the OpenAI Startup Fund **Limitações:** A paid subscription is required after the 7-day free trial; Exact pricing is shown inside the app and varies by region, so it is hard to compare before signing up; Learning content targets the languages Speak supports rather than the full range of world languages; Conversation-first design means less emphasis on reading and writing drills [Profile (Markdown)](https://openaitools.app/pt/tool/speak.md) ## Perguntas frequentes ### Como Knowt e Speak se comparam em tráfego mensal?
