[OWSM-CTC](https://arxiv.org/abs/2402.12654) is an encoder-only speech foundation model based on multi-task self-conditioned CTC.
It is trained on 180k hours of public audio data for multilingual speech recognition, any-to-any speech translation, and language identification, which follows the design of the previous [encoder-decoder OWSM](https://arxiv.org/abs/2401.16658).
