    • There is disclosed an analyser (101) for building a transcription model (112; 500) using a training database (111) of music. The analyser (101) decomposes the training music (111) into sound events (201a-e) and, in one embodiment, allocates the sound events to leaf nodes (504a-h) of a tree (500). There is also disclosed a transcriber (102) for transcribing music (121) into a transcript (113). The transcript (113) is sequence of symbols that represents the music (121), where each symbol is associated with a sound event in the music (121) being transcribed. In one embodiment, the transcriber (102) associates each of the sound events (201a-e) in the music (121) with a leaf node (504a-h) of a tree (500); in this embodiment the transcript (113) is a list of the leaf nodes (504a-h). The transcript (113) preserves information regarding the sequence of the sound events (201a-e) in the music (121) being transcribed.
    • 公开了一种使用音乐的训练数据库(111)来构建转录模型(112; 500)的分析器(101)。 分析器(101)将训练音乐(111)分解为声音事件(201a-e),并且在一个实施例中,将声音事件分配给树(500)的叶节点(504a-h)。 还公开了用于将音乐(121)转录成抄本(113)的抄录器(102)。 成绩单(113)是表示音乐(121)的符号序列,其中每个符号与被转录的音乐(121)中的声音事件相关联。 在一个实施例中,转录器(102)将音乐(121)中的每个声音事件(201a-e)与树(500)的叶节点(504a-h)相关联; 在该实施例中,转录本(113)是叶节点(504a-h)的列表。 转录本(113)保存关于正在转录的音乐(121)中的声音事件(201a-e)的顺序的信息。
