I'm getting a warning using the noise_cancellation.BVCTelephony() plugin. Here is my setup, but I'm getting this error: Expected type 'NoiseCancellationOptions | None', got 'BVCTelephony' instead

if is_text_only:
        # Text-only participant: enable text, disable audio
        room_input_options = RoomInputOptions(text_enabled=True)
        room_output_options = RoomOutputOptions(audio_enabled=False)
    else:
        # Voice participant: enable audio, enable text
        room_input_options = RoomInputOptions(
            noise_cancellation=noise_cancellation.BVCTelephony(),
            pre_connect_audio=True,
            text_enabled=True,
            audio_enabled=True,
        )
        room_output_options = RoomOutputOptions(audio_enabled=True)

Thanks for reaching out, Brandon. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

Did you import

from livekit.plugins import noise_cancellation

? The

BVCTelephony()

instance you're creating should be compatible with

rtc.NoiseCancellationOptions

. This type mismatch warning might be due to: 1. Import issues: Ensure you're importing the noise cancellation module correctly 2. Type checker configuration: Your IDE or type checker might not be recognizing the inheritance relationship 3. Version mismatch: There might be a version incompatibility between your type definitions and runtime To resolve this, verify your imports and ensure you're using compatible versions of the LiveKit agents library. The pattern you're using matches the established examples in the codebase, so this appears to be a type annotation issue rather than a functional problem.

Yes. Everything is imported correctly. I am using PyCharm and I've encountered type warnings like this before with this IDE. I'll write off my issue as being just that. Thanks for the help!

oh, I see. I thought you were talking about a runtime warning.

I just ran:

pip freeze > requirements.txt

Turns out my packages were a bit outdated. I'm on the newest versions for everything now. Just updated and the warning went away and noise cancellation improved. I apologize for the miscommunication and I appreciate the help.
