Two-dimensional t-SNE projection of ECAPA-TDNN utterance embeddings. (a) Hue determined by speaker ID. (b) Hue determined by speech style. Note. Each marker represents one speech utterance and, as illustrated by (a), each cluster of markers represents utterances by one speaker. When visualizing the colors of each dot based on its speech (trial) style (b), we see that generally the individual speech styles cluster together within each speaker's utterances. This hints towards a separability of speech styles based on speaker identification techniques using acoustic properties
