+# Speaker embeddings extracted from CMU ARCTIC
+
+There is one `.npy` file for each utterance in the dataset, 7931 files in total. The speaker embeddings are 512-element X-vectors.
+
+The [CMU ARCTIC](http://www.festvox.org/cmu_arctic/) dataset divides the utterances among the following speakers:
+
+- bdl (US male)
+- slt (US female)
+- jmk (Canadian male)
+- awb (Scottish male)
+- rms (US male)
+- clb (US female)
+- ksp (Indian male)
+
+The X-vectors were extracted using [this script](https://huggingface.co/mechanicalsea/speecht5-vc/blob/main/manifest/utils/prep_cmu_arctic_spkemb.py), which uses the `speechbrain/spkrec-xvect-voxceleb` model.
+
+Usage:
+
+```python
+from datasets import load_dataset
+embeddings_dataset = load_dataset("Matthijs/cmu-arctic-xvectors", split="validation")
+
+speaker_embeddings = embeddings_dataset[7306]["xvector"]
+speaker_embeddings = torch.tensor(speaker_embeddings).unsqueeze(0)
+```
