ERROR: Failed to detect voice's [en-USGuyNeural] endpoint for synthesizing.

Question

I am running into an error when changing voice using the Speech Studio.

If I change voices in the SSML file, the synthesizer outputs an error. Below is a script that generates the error.

Answer 1

This issue is fixed by moving the <break> before the </voice>.
