I’m building an EdTech application focused on helping users practise and improve their spoken English, and I want it delivered as a fully-functional Flutter app for Android. The core experience should let learners speak, listen, and receive instant feedback while keeping the interface clean, modern, and intuitive. Here’s what I need from you: develop the complete code-base in Flutter, wire up any necessary back-end or third-party speech services, and make sure the build runs smoothly on current Android devices. You’re free to recommend the best libraries or APIs for speech recognition and audio playback, as long as they integrate cleanly with Flutter and fit within standard store guidelines. The finished APK (plus source code) is my primary deliverable. I should be able to open the project in Android Studio, run flutter pub get, and build without extra tweaks. Let’s keep communication straightforward—short video demos or TestFlight-style builds during milestones are ideal so I can test pronunciation feedback, UI flow, and overall performance. If this sounds like your kind of project, let’s discuss your proposed architecture and timeline.

You’re aiming for a fully-functional Flutter (Android) EdTech app that turns spoken English practice into clear “speak → listen → instant feedback”. I’ll deliver a complete Flutter code-base with a modern, distraction-free UI flow, plus APK + source so it builds cleanly in Android Studio (flutter pub get, then release build). For speech, I’ll use Flutter-compatible solutions (e.g., Google Speech / on-device options where feasible) and pair them with robust audio playback and session controls (start/stop, retry, buffering, error handling). The feedback layer will be designed to be fast and consistent, so learners get timely guidance without UI lag. You’ll receive milestone video demos to validate pronunciation feedback quality, interaction states, and performance on current Android devices. At the end, you’ll get a store-guideline-friendly APK bundle (with source) ready for testing. Including your key insertion point: Calmly and inclusively: which exact speech-feedback quality metrics (accuracy vs fluency vs pronunciation scoring) do you want surfaced in the app, and from which data sources?

Hello, I reviewed your Android EdTech Flutter App project and it immediately stood out because a well-designed learning app can significantly improve student engagement and learning outcomes. Problem: EdTech applications often struggle with course management, quiz performance, real-time progress tracking, offline learning, and scalability, resulting in a less engaging learning experience. Solution: I can develop a high-performance Flutter application with secure authentication, course management, quizzes and assessments, progress tracking, video lessons, push notifications, offline support, REST API integration, and an intuitive admin panel. My experience includes Flutter, Dart, Laravel, Firebase, MySQL, REST APIs, and cross-platform mobile application development. Result: You will receive a fast, secure, and scalable EdTech application that delivers a seamless learning experience, simplifies content management, and provides a strong foundation for future growth. A few questions: • Is the application for students only, or will it also include separate panels for teachers and administrators? • Which features are required in the MVP—video lessons, quizzes, live classes, assignments, certificates, or progress tracking? • Is the backend already available, or should the APIs and admin panel be developed as part of the project? • Do you already have the UI/UX designs in Figma, or should they be designed during development? Thanks

Hi, Your project is a great fit for my experience. I've recently built **real-time AI voice applications** using **Flutter**, integrating **Whisper, Deepgram, ElevenLabs, Azure Speech**, and **RAG-based AI assistants** with low-latency audio streaming and instant feedback. For your English learning app, I'd recommend: * **Flutter** for Android (easily extensible to iOS) * **FastAPI** backend * **OpenAI Whisper/Deepgram** for speech recognition * **GPT-4/Claude** for grammar, fluency, and pronunciation feedback * **ElevenLabs/Azure Speech** for natural voice playback * **Supabase** for user progress and analytics This architecture provides **real-time speaking practice, instant AI feedback, conversation history, and a scalable foundation** for future lessons and gamification. **Timeline:** **2–3 weeks** **Budget:** **USD 900–1000** **One question:** Do you want users to have **free-flowing AI conversations**, or should the app guide them through **structured lessons and role-play scenarios** with feedback after each exercise? **Best,** Virander

Hello, Your project is an excellent fit for my Flutter development experience. Building an English-speaking practice app requires more than integrating speech recognition—it needs a responsive architecture that delivers accurate pronunciation feedback, smooth audio playback, and an engaging learning experience. For this project, I recommend Flutter with a clean, modular architecture, paired with a lightweight backend (if required) for user management, progress tracking, and analytics. For speech capabilities, I can integrate industry-standard speech recognition and text-to-speech services that comply with Play Store guidelines while providing real-time pronunciation feedback. The application would include: * Clean, modern, and intuitive Flutter UI * Speech-to-text for spoken English practice * Audio playback with pronunciation guidance * Instant pronunciation and speaking feedback * Progress tracking and session history * Responsive performance across current Android devices * Well-structured, documented source code I follow clean architecture principles, making the project easy to maintain and extend with future features such as AI conversation practice, grammar correction, gamification, or multilingual support. Throughout development, I'll share regular milestone builds and short demo videos so you can validate the pronunciation engine, UI flow, and overall experience before moving to the next phase.

I can design and build your spoken-English EdTech app as a fully functional Flutter Android application, from clean UI to reliable speech interaction. I’ll focus on a smooth practice experience: speak, listen back, and receive clear feedback inside an intuitive, modern interface. I’ve delivered Flutter apps that integrate speech recognition, audio playback, and cloud APIs, ensuring they pass store guidelines and run consistently on current Android devices. I’m also comfortable setting up back-end or third‑party services so everything works with one click in Android Studio. My approach: define the core practice flows, select robust speech/voice APIs, then implement a modular Flutter architecture with proper state management. I’ll provide APKs and short video demos at milestones, and ensure the final source builds cleanly with flutter pub get and standard tooling. Quick question before I suggest an architecture: Do you already have any preferred speech API (e.g., Google, Azure) or are you open to recommendations?
