Abstract

The rapid progress in technology has transformed the way people learn languages, offering students innovative tools to improve their skills. SpeakBuddy is built using the Flutter framework and utilizes Azure Speech AI for speech functionalities. Speak Buddy incorporates various features, such as interactive conversation practice, detailed lessons covering vocabulary, grammar, and pronunciation, fun games, and AI-powered voice assistance. The app's creation involved several design cycles where feedback from language experts and user testing was used to ensure it was easy to use and effective. Continuous assessments were conducted to evaluate the app's usability, performance, and impact on language learning outcomes. The results showed high levels of satisfaction among users, who reported feeling more confident and proficient in spoken English after using the app. A key feature of Speak Buddy is its ability to provide instant feedback on pronunciation, helping students improve their speaking skills.
