I am building a simple Python application using continuous speech translation through the Azure Cognitive Services Speech SDK. Translation and detection between languages works as far as I can tell. My goal is to update the UI according to the detected language. However, I cannot get a detected language signal. The docs say that for Python continuous language detection works. Can I get a signal for the detected language?

My question is about:

speechsdk.languageconfig.AutoDetectSourceLanguageConfig(self.detectable_languages)

I am setting the languages according to the SDK specs using the language code and locale:

detectable_languages = ["en-US", "es-MX"]

This is where I am configuring the translation recognizer:

speech_translation_config.set_property(property_id=speechsdk.PropertyId.SpeechServiceConnection_LanguageIdMode, value='Continuous')

def configure(self):
        self.speech_translation_config = self.init_speech_translation_config()
        self.audio_config = self.set_audio_source()
        self.auto_detect_source_language_config =  speechsdk.languageconfig.AutoDetectSourceLanguageConfig(self.detectable_languages)
        print("Detectable languages set in AutoDetectSourceLanguageConfig:")
        print(self.auto_detect_source_language_config.languages)
        self.translation_recognizer = self.init_translation_recognizer()
        self.set_event_callbacks()

When I run my app I get this output:

'AutoDetectSourceLanguageConfig' object has no attribute 'languages

It seems to me I should get a signal for “en-US” or “es-MX”.
