Method for searching data in at least two databases

本发明涉及用于在至少两个数据库(D#-[n])中搜索数据的方法数据库系统，该方法数据库系统特别用于在至少两个电话号码簿、地址簿或者组织者数据库等等中搜索电话号码簿、地址簿或者组织者记录等等。通过语音识别来允许对两个或者多个数据库同时进行访问，以便能够在其中实现搜索就像在一个单独的数据库中进行搜索一样，搜索项经由话音控制的用户接口(28)通过语音加以输入，所述话音控制的用户接口被连接到数据库主控制设备(26)，并且包含语音识别前端装置(8，9)，该前端装置用于处理通过语音输入的搜索项的声音序列，以便获得它的可比较语音模式(X)。通过与数据库(D#-[1]-D#-[6])相连的语音识别后端装置(6)，比较该可比较语音模式(X)与相应的数据库记录(E#-[n，j])的语音模式(A#-[n，i])，以便为至少两个数据库(D#-[n])中的每一个确定其语音模式(A#-[n，i])与所述搜索项的可比较语音模式(X)最佳匹配的至少一个数据库记录(E#-[n，j])。其后，数据库主控制设备(26)的语音识别中间部分装置(7)从前一步骤中确定的记录(E#-[n，j])中选择搜索项最佳的数据库记录(E#-[p，j])，其中数据库记录(E#-[p，j])被存储在相关的搜索表存储器(27)中。至少，在前一步骤已被选择的数据库记录(E#-[p，j])的标识符被输出。 The present invention relates to a method database system for searching data in at least two databases (Dn), in particular for searching telephone directory, address book or organizer entries or the like in at least two telephone directory, address book or organizer databases or the like. To allow simultaneous access to two or more databases by means of speech recognition in order to be able to perform a search therein as in a single database a search term is input by speech via a voice controlled user interface (28) that is connected to a database primary control apparatus (26) and comprises speech recognition front end means (8, 9) for processing a sound sequence of a search term input by speech to obtain a comparable speech pattern (X) thereof. By means of speech recognition back end means (6) associated with databases (D1-D6) the comparable speech pattern (X) is compared with corresponding speech patterns (An,i) of database entries (En,i) to determine for each of the at least two databases (Dn) at least that database entry (En,j) the speech pattern (An,j) of which matches the comparable speech pattern (X) of the search term best. Thereafter, a speech recognition middle part means (7) of a database primary control apparatus (26) selects that database entry (Ep,j) the speech pattern (Ap,j) of which matches the comparable speech pattern (X) of the search term best from the entries (En,j) determined in the previous step and stored in an associated search table memory (27). At least, an identifier of that database entry (Ep,j) that has been selected in the previous step is output.
