I have changed the line 299

 config = speech.RecognitionConfig(
        encoding=speech.RecognitionConfig.AudioEncoding.LINEAR16,
        sample_rate_hertz=SAMPLE_RATE,
        language_code="en-US",
        max_alternatives=1,
    )

into

 config = speech.RecognitionConfig(
        encoding=speech.RecognitionConfig.AudioEncoding.LINEAR16,
        sample_rate_hertz=SAMPLE_RATE,
        language_code="ja-JP",
        max_alternatives=1,
    )

Describe the issue

streaming_recognize() method doesn't work properly. For even when a speaker utters a simple greeting like こんにちは in a very silent environment, this method returns StreamingRecognizeResponse object with a result of is_final == False. And always returns a result with is_final set to True exactly 90 seconds later.
this doesn't happen when the language is English or Chinese.
The same thing also happens in transcribe_streaming_infinite_v2.py

I am not sure if this report should be post here for this seems to be more internal problem.
Appreciate any help or clues anyways.
