Fun-ASR-Nano (Hugging Face Transformers)
This is the Hugging Face Transformers-compatible version of Fun-ASR-Nano-2512.
Fun-ASR-Nano is an end-to-end speech recognition model by FunAudioLLM, trained on tens of millions of hours of real speech data. It supports multilingual speech recognition covering Chinese (with dialects), English, Japanese, Korean, and many more languages.
Transformers quickstart
Fun-ASR-Nano support is being added to Transformers in huggingface/transformers#46180. Until it is included in a Transformers release, use a build containing that PR.

Expected transcription:
The tribal chieftain called for the boy, and presented him with fifty pieces of gold.
