Synthesizer skips over embeddings file if model only has one speaker

[wonkothesanest]

It looks like the Neon model is special in that t does not have a speaker_name and it wants to get the only item available. This was blocking a valid model with one speaker and a d_vector_file from being executed to get the embedding.

Leaving the check to be second still works fine for the case that there is only one model and no speaker name.

This is in reference to bug 2320

Can someone please guide me to some documentation on how to get the tests to pass? I believe there is not a correct token setup for Coqui TTS.
"No API token found for 🐸Coqui Studio voices - https://coqui.ai/ \n"

@erogol I'm sorry to bug you (and please take your time, I just wanted to tag you to make sure I wasn't expected to do something else). Do you have any tips for getting the tests to pass, do I need an API key?

[wonkothesanest]

I have 5 failing tests all of which seem to have to do with not having a Coqui Studio Token. Can someone please help me understand how I might be able to fix this issue? I don't see where I could set the environment to add this token.
