voice settings

[premmaity]

hi
i am working over a project so i need a real time tts model for the project. I came across this RealtimeTTS and using EdgeEngine
but i am facing problem as i am trying to change the voice of the engine

my code is

from RealtimeTTS import TextToAudioStream, SystemEngine, AzureEngine, ElevenlabsEngine, EdgeEngine,GTTSEngine
from time import time
text_stream='''
hello prem
'''

engine=EdgeEngine().set_voice("en-IN-NeerjaNeural")

stream=TextToAudioStream(engine)

a=time()
stream.feed(text_stream)
b=time()
print(b-a)
stream.play()

error is

C:\Users\Prem\Desktop\innerve\MY_TTS\venv\Scripts\python.exe C:\Users\Prem\Desktop\innerve\MY_TTS\realtime.py
Traceback (most recent call last):
File "C:\Users\Prem\Desktop\innerve\MY_TTS\realtime.py", line 9, in

format, channels, rate = self.engine.get_stream_info()
^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'get_stream_info'

Process finished with exit code 1

can anyone help me in changing the voice and speed of voice

engine=EdgeEngine().set_voice("en-IN-NeerjaNeural")

This code creates a temporary EdgeEngine, calls set_voice and then sets the value of your engine variable to the return value of set_voice, which is None. Therefore later you get the "AttributeError: 'NoneType' object has no attribute 'get_stream_info'" in the line getformat, channels, rate = self.engine.get_stream_info(), because your self.engine is None.

Change above code to:

engine=EdgeEngine()
engine.set_voice("en-IN-NeerjaNeural")

and you should be good.
