# π₯ Whisper-NER: ASR with zero-shot NER | |
WhisperNER is a unified model for automatic speech recognition (ASR) and named entity recognition (NER), with zero-shot capabilities. | |
The WhisperNER model is designed as a strong base model for the downstream task of ASR with NER, and can be fine-tuned on specific datasets for improved performance. | |
The [aiola/whisper-ner-tag-and-mask-v1](https://huggingface.co/aiola/whisper-ner-tag-and-mask-v1) model was finetuned from | |
the [aiola/whisper-ner-v1](https://huggingface.co/aiola/whisper-ner-v1) checkpoint using the NuNER dataset to perform joint audio transcription and NER tagging or NER masking. | |
The model was not trained on PII specific datasets, hence can perform general and open type entity masking. | |
It should be further finetuned in order to be used for PII detection. The model was trained and evaluated only on English data. Check out the paper for full details. | |
