What does [ALARM SOUNDING] mean in Gemini's API?

When i send a requst to Gemini-1.5-pro API with aduio and prompt like that:

response = model.generate_content([prompt, audio_file])

Occasionally, i got response text like that:

{“text”: “{"text": "[ALARM SOUNDING]"}\n” }

And what doed this flag mean ?

Thanks.

This isn’t a flag. This is a response.

Remember that Gemini (and all LLMs) are just pattern systems. They are designed to take a pattern (your prompt) and then continue the pattern (the reply). You don’t show what your prompt is, but it has prompted Gemini to continue the pattern with that response.
