Brighton Etornam Sunu, a Google Developer Expert, presented a YouTube video demonstrating an application built using ElevenLabs and Google Gemini. The app addresses accessibility challenges for visually impaired individuals by converting spoken words into text using speech-to-text, processing the text through Gemini to generate a response, and then using ElevenLabs to synthesize the response into audible speech. The application's source code, a Flutter project, is available on GitHub. The presenter showcased the app's functionality, highlighting the integration of multiple AI APIs to achieve natural-sounding audio responses to user's voice commands. The video concludes with an invitation to explore and improve upon the provided code.
