    • A method and apparatus for laughter detection. Laughter is detected through the presence of a sequence of at least a predetermined number such as three consecutive bursts, each burst comprising a voiced portion and an unvoiced portion. After detecting bursts, n-tuples such as triplets are detected, and a likelihood of each burst N-tuple to represent laughter is provided by comparison to predetermined thresholds. Finally, a total score is assigned to the signal based on the grades associated with the triplets and parameters such as the distance between the N-tuples, the total score representing the probability that the audio signal comprises a laughter episode. The method and apparatus preferably comprise a training step and module for determining the thresholds according to manually marked audio signals.
    • 一种用于笑声检测的方法和装置。 通过存在至少预定数量的序列(例如三个连续脉冲串)来检测笑声,每个脉冲串包括有声部分和无声部分。 在检测到突发之后,检测诸如三元组的n元组,​​并且通过与预定阈值进行比较来提供每个突发N元组表示笑声的可能性。 最后,基于与三元组相关联的等级和诸如N元组之间的距离的参数将总分数分配给信号,总分表示音频信号包括笑声情节的概率。 该方法和装置优选地包括用于根据手动标记的音频信号来确定阈值的训练步骤和模块。
