Voicelator is a voice and text translator that allows users to eliminate language barriers and communicate while traveling around the world. The app delivers fast and accurate translations due to real-time voice recognition. Users can pronounce or type the text they want to translate, and Voicelator speaks or displays the text in the target language.

    Voice Translator

    To implement voice translation, we used AVFoundation to view translations in full screen on the user’s phone with no hindrance whatsoever. To allow users to receive translations in real-time immediately when they type in or voice out any language, we used Google API with recognition on neural networks. In addition to translations with AVFoundation, we implemented a voice playback feature with the opportunity to choose between male or female voices, which could make the user experience even more pleasant.

  2. Text Translator

    Our team used native technologies and Realm database to develop a text translator function that gives users the ability to translate between 100+ languages in online and offline modes easily.

    The app allows users to save the translations to Favourites and create their words database. Thus, app users can build up lists for future reference, ready for when they go on vacation, for example.

Project Results

Our team developed a brand-new mobile app that gained over 100 thousand downloads and more than 2000 reviews in the App Store in just two months after release. Using the latest technologies and speech recognition software, Voicelator listens to the user's voice, converts the spoken text into the desired language in real-time, and displays it on the screen, making communication and translation seamless.
