# Whisper Large Spanish |
|
|
|
This model is a fine-tuned version of [openai/whisper-large-v2](https://huggingface.co/openai/whisper-large-v2) on Spanish using the train split of [Common Voice 11](https://huggingface.co/datasets/mozilla-foundation/common_voice_11_0). |
|
|
|
## Usage |
|
|
|
```python |
|
|
|
from transformers import pipeline |
|
|
|
transcriber = pipeline( |
|
"automatic-speech-recognition", |
|
model="jonatasgrosman/whisper-large-es-cv11" |
|
) |
|
|
|
transcriber.model.config.forced_decoder_ids = ( |
|
transcriber.tokenizer.get_decoder_prompt_ids( |
|
language="es", |
|
task="transcribe" |
|
) |
|
) |
|
|
|
transcription = transcriber("path/to/my_audio.wav") |
|
|
|
``` |
|
|
|
## Evaluation |
|
|
|
I've performed the evaluation of the model using the test split of two datasets, the [Common Voice 11](https://huggingface.co/datasets/mozilla-foundation/common_voice_11_0) (same dataset used for the fine-tuning) and the [Fleurs](https://huggingface.co/datasets/google/fleurs) (dataset not seen during the fine-tuning). As Whisper can transcribe casing and punctuation, I've performed the model evaluation in 2 different scenarios, one using the raw text and the other using the normalized text (lowercase + removal of punctuations). Additionally, for the Fleurs dataset, I've evaluated the model in a scenario where there are no transcriptions of numerical values since the way these values are described in this dataset is different from how they are described in the dataset used in fine-tuning (Common Voice), so it is expected that this difference in the way of describing numerical values will affect the performance of the model for this type of transcription in Fleurs. |
