Model Card for whisper-large-v3-taiwanese-hakka
This model is a fine-tuned version of the Taiwanese Hakka openai/whisper-large-v3, which uses the ids of each dialect as prompts during training, to experiment whether the addition of prompts to the finetune of whisper when using multiple dialects will give better results.
