Hi,
some languages offer more than one voice, so you could pick a matching voice. For some chinese voices different roles are supported, as described here: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/speech-synthesis-markup?tabs=csharp#role , but this does not seem to be supported by other languages (https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/language-support?tabs=stt-tts#voice-styles-and-roles )
