"}\n",

"### 规则说明\n",
"\n",
"- `audio`：音频文件名。\n",
"- `total_nonbreak`：\n",
" - `true` 表示整段音频没有触发打断信号；\n",
" - `false` 表示音频中触发了打断信号。\n",
"- `break_time`：\n",
" - 当 `total_nonbreak = true` 时，`break_time` 通常为 `-1`；\n",

"\n",
"```json\n",

" \"total_nonbreak\": \"Whether the entire audio contains no interruption signal\",\n",

"\n",
"- `audio`: the audio filename.\n",
"- `total_nonbreak`:\n",
" - `true` means no interruption signal was triggered throughout the entire audio;\n",
" - `false` means an interruption signal was triggered in the audio.\n",
"- `break_time`:\n",
" - When `total_nonbreak = true`, `break_time` is usually `-1`;\n",
" - When `total_nonbreak = false`, `break_time` indicates the timestamp of the first interruption signal, in seconds.\n"
