摘要： Embodiments for measuring content coherence and embodiments for measuring content similarity are described. Content coherence between a first audio section and a second audio section is measured. For each audio segment in the first audio section, a predetermined number of audio segments in the second audio section are determined. Content similarity between the audio segment in the first audio section and the determined audio segments is higher than that between the audio segment and all the other audio segments in the second audio section. An average of the content similarity between the audio segment in the first audio section and the determined audio segments is calculated. The content coherence is calculated as an average, the maximum or the minimum of the averages calculated for the audio segments in the first audio section. The content similarity may be calculated based on Dirichlet distribution.
摘要翻译：描述了用于测量内容相干性的实施例和用于测量内容相似性的实施例。测量第一音频部分和第二音频部分之间的内容相干性。对于第一音频部分中的每个音频段，确定第二音频部分中的预定数量的音频片段。第一音频部分中的音频片段与所确定的音频片段之间的内容相似性高于音频片段和第二音频片段中的所有其他音频片段之间的内容相似度。计算第一音频部分中的音频片段与确定的音频片段之间的内容相似度的平均值。内容相干性被计算为平均值，对于第一音频部分中的音频段计算的平均值的最大值或最小值。内容相似性可以基于Dirichlet分布来计算。
