Agent can not submit message when using google stt in Japanese

[xubujie]

Issue

When using google STT, and set anguages=["en-US"], everything works just fine. But when set languages to ["ja-JP"], when test in playground, it just listen user speech forever,

Code

assistant = VoiceAssistant(
        vad=silero.VAD(),  # Voice Activity Detection
        stt=google.STT(
            languages=["ja-JP"],
        ),  # Speech-to-Text
        # stt=openai_stt,
        llm=gpt,  # Language Model
        tts=openai_tts,
        chat_ctx=initial_ctx,  # Chat history context
        debug=True,
        allow_interruptions=False,
    )
