Wakeword engine oww unknown/unsupported or wake_words not specified. Please specify one of: pvporcupine, openwakeword. NoneType: None

Hi! I found that this issue still exists in the current version:
Unable to use 'oww' as the wake word engine, the error is as follows:

RealTimeSTT: realtimestt - ERROR - Wakeword engine oww unknown/unsupported or wake_words not specified. Please specify one of: pvporcupine, openwakeword.

Could you please resolve it as soon as possible? Thank you!

Alright, I found the issue:
Even if the pvporcupine engine is not used, the wake_words parameter must not be omitted.

I think this is unreasonable.
When using wakeword_backend='oww', it should check the openwakeword_model_paths parameter instead of the wake_words parameter.

[leap233]

I have discovered a new issue: when using "oww" as the wake word engine, it does not respond to voice and fails to detect the wake word. Why is that?

experiencing this same issue with wakeword_backend='oww' in current version.

^^^^^^^^^^^^^
AttributeError: 'AudioToTextRecorder' object has no attribute 'owwModel'

Looking into your library i found self.owwModel is not present.
pvporcupine works well but wakeword_backend='oww' , throws error.

even with your example it throws error.

[leap233]

当前版本中 wakeword_backend='oww' 也遇到了同样的问题。

AttributeError：“AudioToTextRecorder”对象没有属性“owwModel”

查看您的库，我发现 self.owwModel 不存在。pvporcupine 运行良好，但 wakeword_backend='oww' 会引发错误。

即使按照你的例子，它也会引发错误。

Try setting wake_words=xxx
Use the oww engine promptly

adding wake_words=.... gives below error:

I was getting the same issue. Resolved by using the below:

with AudioToTextRecorder(
        model='small',
        language='en',
        wakeword_backend='oww',
        wake_words="hey jarvis",
        spinner=True,
        device='cpu',
    ) as recorder:
        while True:
            query = recorder.text(process_text)

by specifying wakeword_backend='oww' and wake_words='hey jarvis' based on the pretrained model wake words found here: https://github.com/dscripka/openWakeWord?tab=readme-ov-file#pre-trained-models
