    • In one aspect, an example method for outputting an alert indicating a functional state of a back-up audio-broadcast system involves: a computing device receiving a first audio-stream that represents first audio-content; the computing device generating a first signature based, at least in part, upon an extent of mute/non-mute transitions included within the first audio-content; the computing device receiving a second audio-stream that represents second audio-content; the computing device generating a second signature based, at least in part, upon an extent of mute/non-mute transitions included within the second audio-content; the computing device making a determination that the generated first-signature and the generated second-signature lack a threshold extent of similarity; and responsive to the determination that the generated first-signature and the generated second-signature lack the threshold extent of similarity, the computing device outputting an alert.
    • 一方面,一种用于输出指示备用音频广播系统的功能状态的警报的示例方法包括:接收代表第一音频内容的第一音频流的计算设备; 所述计算设备至少部分地基于包括在所述第一音频内容内的静音/非静音转换的程度来生成第一签名; 所述计算设备接收表示第二音频内容的第二音频流; 所述计算设备至少部分地基于包括在所述第二音频内容内的静音/非静音转换的程度来生成第二签名; 所述计算装置确定所生成的第一签名和所生成的第二签名缺少阈值相似程度; 并且响应于所生成的第一签名和所生成的第二签名缺少阈值相似度的确定,所述计算设备输出警报。
