    • The present invention provides a method and apparatus for training a prosody statistic model and prosody parsing, a method and system for text to speech synthesis. Said method for training a prosody statistic model with a raw corpus that includes a plurality of sentences with punctuation, comprising: transforming said plurality of sentences in said raw corpus into a plurality of token sequences respectively; counting a frequency for each adjacent token pair occurring in said plurality of token sequences and frequencies of punctuation that represents a pause occurring at associated positions of said each token pair; calculating pause probabilities at said associated positions of said each token pair; and constructing said prosody statistic model based on said token pairs and said pause probabilities at associated positions thereof. With the present invention a prosody statistic model can be trained from a raw corpus without manually prosody parsing tags. And the prosody statistic model can be used in the prosody parsing and further voice synthesis.
    • 本发明提供了一种用于训练韵律统计模型和韵律解析的方法和装置,一种用于文本到语音合成的方法和系统。 用于训练具有包括多个具有标点符号的句子的原始语料库的韵律统计模型的所述方法,包括:分别将所述原始语料库中的所述多个句子变换成多个令牌序列; 计算在所述多个令牌序列中出现的每个相邻令牌对的频率和表示在所述每个令牌对的相关联位置发生的暂停的标点符号的频率; 计算所述每个令牌对的所述关联位置处的暂停概率; 以及基于所述令牌对和在其关联位置处的所述暂停概率构建所述韵律统计模型。 利用本发明,可以从原始语料库训练韵律统计模型,而无需手动韵律解析标签。 韵律统计模型可用于韵律解析和语音合成。
