The documentation asks to look at the site Documentation Amazon the voice options, but it generates an error when using one of the best voices in portuguese brazil. The only one that's neural called Camila.

Additional information

I believe it should just be a matter of including that voice in the integration template. The voice . The other voices of Ricardo and Vitoria available are very bad, very robotic.
