Youth Voice | Anna Laura Seifermann: Viamo/Sentreso’s GenAI Voice Assistant Enables Offline Native Language Queries

At the 2025 Acceleration Week for Global Youth Development, Anna Laura Seifermann, Director at Viamo and Co-Founder of Sentreso in Senegal, introduced her Voice-First GenAI Companion Program.

This GenAI-powered voice assistant enables users to ask questions in their native language using any basic mobile phone—no smartphone or internet required. Users simply dial a dedicated number and speak their query. The system converts speech to text, searches relevant databases (AVA uses a general knowledge base, while AAE draws from partner-provided professional databases), and delivers personalized spoken responses within seconds via text-to-speech technology.(Camera: Gao Rongjian, He Yao; Editor: Wang Shuocheng)
