"""## Building a Demo

Now that we've fine-tuned our model we can build a demo to show 
off its ASR capabilities! We'll make use of 🤗 Transformers 
`pipeline`, which will take care of the entire ASR pipeline, 
right from pre-processing the audio inputs to decoding the 
model predictions.

Running the example below will generate a Gradio demo where can input audio to 
our fine-tuned Whisper model to transcribe the corresponding text:
