from transformers import pipeline
pipe = pipeline("text-to-speech", model="YOUR_ACCOUNT_NAME/speecht5_finetuned_voxpopuli_nl")

Pick a piece of text in Dutch you'd like narrated, e.g.:

text = "hallo allemaal, ik praat nederlands. groetjes aan iedereen!"

To use SpeechT5 with the pipeline, you'll need a speaker embedding. Let's get it from an example in the test dataset: 

example = dataset["test"][304]
speaker_embeddings = torch.tensor(example["speaker_embeddings"]).unsqueeze(0)
