[Bug Report] It appears that the Azure Python SDK currently does not support emotion settings for speech synthesis.

Hi,

I'm trying to set the voice emotion using the following code:

from RealtimeTTS import TextToAudioStream, AzureEngine

engine = AzureEngine(
    speech_key=speech_key,
    service_region=service_region,
    voice="zh-CN-XiaoxiaoMultilingualNeural",  # New voice
    rate=0
)
engine.emotion = "empathetic"
engine.emotion_degree = 1.0
engine.emotion_role = "YoungAdultFemale"

However, this doesn't seem to have any effect. I then tried using the SSML approach, and it worked perfectly. This raises the question: does the emotion setting still function in RealtimeTTS?

Here's the SSML code that worked:

ssml = f"""
<speak version="1.0" xmlns="http://www.w3.org/2001/10/synthesis" xmlns:mstts="https://www.w3.org/2001/mstts" xml:lang="zh-CN">
    <voice name="zh-CN-XiaoxiaoNeural">
        <mstts:express-as style="empathetic">
            {content}
        </mstts:express-as>
    </voice>
</speak>
"""

result = synthesizer.speak_ssml_async(ssml).get()

I will check that
