摘要

PPROBLEM TO BE SOLVED: To provide clustering technology for accurately estimating the number of speakers and a parameter for characterizing each speaker, in dialization. PSOLUTION: A clustering calculation device 3 includes: an observation amount creation section 26 which reads a power vector extracted from recorded conversation data, to convert it to an observation amount of the vector corresponding to dynamic Hierarchical Dirichlet Process (dHDP) approximation model; a storage means 10 for accumulating and storing a collection data of the converted observation amount; a variation post-distribution inference section 30 in which a value of post-distribution of a plurality of parameters when the plurality of clusters are created from the collection data of the observation amount by dHDP approximation model, is respectively estimated by an expectation-maximization (EM) algorithm, and sequentially stored and updated in the storage means 10; and an output control section 28 for outputting a latest estimation value of the post-distribution of the plurality of parameters, which are stored in the storage means 10, when a finishing condition set beforehand is satisfied.

要解决的问题：在拨号时，提供聚类技术以准确估算发言人的数量以及每个发言人的特征参数。解决方案：聚类计算设备3包括：观察量创建部分26，该观察量创建部分26读取从记录的会话数据中提取的幂矢量，以将其转换为与动态分层狄利克雷特处理（dHDP）近似模型相对应的矢量的观察量;存储装置10，用于累积并存储转换后的观察量的收集数据;变化后分布推断部分30，其中当通过dHDP近似模型从观测量的收集数据创建多个聚类时，多个参数的后分布的值分别通过期望最大化来估算（ EM）算法，并依次存储和更新在存储装置10中;输出控制部28，当满足预先设定的结束条件时，输出存储在存储单元10中的多个参数的分布后的最新估计值。
