Speech: Include the 'diarization_config' parameter in the RecognitionConfig object.

Hello,

I am trying to include the SpeakerDiarizationConfig to the RecognitionConfig via the ‘diarization_config’ parameter but I am not being able to do that and I don’t see any example on the documentation page in order to make it work.

My approach looks as follow:

diarization_config = { "enableSpeakerDiarization": True, "minSpeakerCount": 2, "maxSpeakerCount": 3}

config = types.RecognitionConfig( encoding=enums.RecognitionConfig.AudioEncoding.LINEAR16, sample_rate_hertz=frame_rate, language_code="es-ES", enable_word_time_offsets=True, diarization_config=diarization_config, enable_automatic_punctuation=True)

As far as I understand, the ‘diarization_config’ is supposed to be a SpeakerDiarizationConfig object but I don’t get how to use it properly.

My actual result is: “ValueError: Protocol message RecognitionConfig has no “diarization_config” field.” In contrast, my expected result is a transcript that includes the ‘speakerTag’ in the word list, like:

{ "startTime": "127.500s", "endTime": "127.700s", "word": "la", "speakerTag": 2 }, { "startTime": "127.700s", "endTime": "129.300s", "word": "direcci\u00f3n.", "speakerTag": 2 }

Thanks in advance for your kind help.

I’ve started the process to release google-cloud-speech 1.3.0 with that feature.

@kamrankausar Speaker diarization is only a beta feature now so you need to use the beta library.

client = speech_v1p1beta1.SpeechClient()
