• Chain-of-Thought Prompting 

Kimi-Audio:

Reasoning process:

1. The energy of the audio is dominated by the sound of rain; the speech by the woman is quieter and occurs later. The onset of speech is around 1.5 seconds.

2. The spoken text is \"The Greeks used to imagine that it was a sign from the gods to foretell war or heavy rain.\"

3. The acoustic scene is likely an outdoor environment with heavy rain, possibly near a road given the faint sound of a car.

4. The distinct sound events detected are 'car; rain'

5. Cross-validating the scene and events, the rain event is consistent with the outdoor acoustic scene, and the car event could be a distant vehicle sound. Thus, the final scene is 'outdoor with heavy rain' and the final events are 'car; rain'.

Scene: outdoor with heavy rain

Events: car; rain

Step-Audio 2 Mini:

Reasoning process: 

1. The energy of the speech is much higher than the background noise, indicating that the speaker started talking after the background noise had already begun.

2. The ASR transcription is \"The Greeks used to imagine that it was a sign from the gods to foretell war or heavy rain.\"

3. The acoustic environment has a mix of speech and background noise. The background noise is characterized by low-frequency rumbling, which suggests a potential outdoor setting like a street or a busy area.

4. The events detected include: car engine; footsteps; door closing; music playing; phone ringing.

5. The scene and events are mutually consistent, as the presence of a car engine, footsteps, door closing, music playing, and phone ringing are typical of an outdoor or semi-public space.
