Case Study: A Vietnamese Language App

Project Overview

Our boutique software company was approached by a client who wanted to create a web-based language learning app for Vietnamese. The goal of the project was to develop a prototype that could accurately assess a user''s pronunciation and provide feedback on their speaking skills.

Challenges

The main challenge faced by our team was capturing high-quality audio recordings of the user''s speech through the browser, and then processing it in real-time using a voice-to-text model. Additionally, we needed to ensure that the app could accurately compare the expected text with the generated text, and provide a score that reflected the user''s pronunciation accuracy.

Solutions

To address these challenges, our team used a combination of cutting-edge technologies, including Web Audio API for audio recording and playback, and a cloud-based speech recognition service for voice-to-text processing. We also developed a custom algorithm to compare the expected text with the generated text, taking into account the nuances of the Vietnamese language.

Technical Details

Results

The prototype was successfully developed and tested with a group of users. The results showed that the app could accurately capture and process audio recordings, and provide feedback on pronunciation accuracy with an average score of 85%. User testing also revealed that the app was easy to use and provided valuable feedback for improving speaking skills.

Benefits

The Vietnamese Language App prototype has the potential to revolutionize language learning for individuals around the world. By providing accurate and instant feedback on pronunciation, learners can improve their speaking skills more quickly and effectively. The app also has the potential to be used in educational institutions and language schools, providing a valuable tool for teachers and instructors.
