 ### Speaker embedding (Experimental)
 
-This is an implementation of https://arxiv.org/abs/1710.10467. This model can be used for voice and speaker embedding. So you can generate d-vectors for multi-speaker TTS or prune bad samples from your TTS dataset. Below is an example showing embedding results of various speakers. You can generate the same plot with the provided notebook. 
+This is an implementation of https://arxiv.org/abs/1710.10467. This model can be used for voice and speaker embedding.
+
+With the code here you can generate d-vectors for both multi-speaker and single-speaker TTS datasets, then visualise and explore them along with the associated audio files in an interactive chart.
