About Conformer2

Conformer-2 is a state-of-the-art speech recognition model developed by AssemblyAI, trained on 1.1 million hours of English audio data. It builds on Conformer-1 with significant improvements in proper nouns (6.8% error rate reduction), alphanumerics (31.7% improvement), and noise robustness (12.0% improvement), while maintaining word error rate parity. The model leverages model ensembling for pseudo-labeling and scaling laws inspired by DeepMind's Chinchilla paper. Additionally, inference latency has been reduced by up to 53.7% compared to Conformer-1, making it suitable for real-time applications. Conformer-2 is designed for real-world audio conditions and is available through AssemblyAI's API.
