Vladyslav Khambir is a software engineer with over 10 years of experience in mobile development and scalable high-load systems. His projects have been used by millions of users in the finance and tech industries. Today, he's focused on his product, VocaTalk, an innovative app for learning English with the help of artificial intelligence.
We spoke with Vlad about how VocaTalk was built, what technologies power it, and how he envisions its future.
The Idea and Purpose of the Project
VocaTalk was born out of a real need: how to learn English in a way that goes beyond memorizing words and grammar rules, to speak the language confidently and fluently. Vlad shared that the idea came from his own experience communicating in an international environment. He noticed that most people lack speaking practice - the chance to train their speech and listen to natural language in near-real conversation scenarios.
VocaTalk solves this with AI-powered dialogue practice, offering natural conversations with a virtual partner who adapts to the user's level and leads the discussion in a way that feels intuitive and engaging.
How It Works
The app is built around Google Gemini AI, which enables realistic conversation flows and smart speech analysis. Users engage in dialogues based on everyday topics - job interviews, travel, business, and daily life situations.
Today, VocaTalk offers:
- Real-time dialogues tailored to the user's language level
- Feedback after each session with AI evaluation of the conversation
- Multilingual interface and hints in the 7 most widely spoken languages
The Tech Stack Behind VocaTalk
When building VocaTalk, Vladyslav focused on modern technologies that ensure the app is flexible, scalable, and ready for constant growth. He emphasized that choosing the right stack was a strategic decision:
"It was important to build an architecture that supports rapid feature development without sacrificing app stability."
VocaTalk is powered by:
- SwiftUI for a modern, responsive user interface
- TCA (The Composable Architecture) for a modular codebase that's easy to scale and maintain
- Tuist for managing and generating Xcode project structure
- Gemini AI for generating and guiding conversations
- Google TTS for high-quality voice synthesis
- Whisper for accurate on-device speech recognition
- RevenueCat for handling subscriptions and monetization
- Xcode Cloud for automated build, test, and release processes
This tech foundation allows for rapid iteration and future scaling.
What's Next
We asked Vladyslav about upcoming plans for the app. He shared a few key updates that are in the works:
- A vocabulary and grammar module with adaptive exercises
- Listening comprehension exercises to boost audio understanding
- Enhanced progress tracking and insights
Why VocaTalk Is a Game-Changer in English Learning
VocaTalk focuses on active learning through conversation. Vladyslav noted that real-time speech and interactive dialogue help users break language barriers faster and build confidence in real-world situations.
The app offers a modern, personalized way to learn English, combining cutting-edge technology with real user needs.
