What is Conformer2?

Conformer-2 Conformer‑2 is an automatic speech recognition model trained on 1.1 million hours of English audio, improving accuracy for proper nouns, alphanumeric text, and noisy environments. It delivers faster inference, reducing transcription time for an hour‑long file from 4.

01 minutes to 1.85 minutes, and offers up to 55 % lower latency across file durations. The model incorporates noisy student–teacher training with an ensemble of teacher models to increase robustness and generalization. Conformer‑2 supports a new API parameter, `speech_threshold`, allowing users to skip low‑speech content and control processing costs.
