Eren Gölge is a Chief Architect of Voice Products based in Germany with 13 years of experience building production-grade AI/ML systems, particularly in text-to-speech and speech synthesis. As a co-founder and former Head of AI at Coqui and an early creator of Mozilla TTS, he has led ML and data teams, designed controllable TTS models like XTTS/YourTTS, and driven major open-source projects used across languages. His hands-on work spans model design, performance optimization (e.g., Tacotron2 tf.function optimizations), vocoder benchmarking, and backend model engineering, reflecting deep expertise from research to productization. He combines startup grit—founding and exiting an earlier company—with academic rigor from Bilkent University, and a knack for turning messy research problems into robust, community-driven code. An uncommon strength is his focus on both low-level performance fixes and community-facing documentation, ensuring models are fast, reproducible, and widely adoptable.
