I could’n find any spanish model just like “asr-crdnn-commonvoice-fr” (speechbrain/asr-crdnn-commonvoice-fr · Hugging Face)
How can I improve/fine-tune speechbrain pre-trained model with additional language speeches in particular Spanish ???
You can search for other ASR models in Models - Hugging Face, but as you mentioned there are no speechbrain models for Spanish at the moment.
For speechbrain specific questions, their Discourse might be a place where you get better answers. https://speechbrain.discourse.group/ They also have a ASR from scratch colab Google Colab
