摘要： A non-transitory processor-readable medium storing code representing instructions to be executed by a processor includes code to cause the processor to receive acoustic data representing an utterance spoken by a language learner in a non-native language in response to prompting the language learner to recite a word in the non-native language and receive a pronunciation lexicon of the word in the non-native language. The pronunciation lexicon includes at least one alternative pronunciation of the word based on a pronunciation lexicon of a native language of the language learner. The code causes the processor to generate an acoustic model of the at least one alternative pronunciation in the non-native language and identify a mispronunciation of the word in the utterance based on a comparison of the acoustic data with the acoustic model. The code causes the processor to send feedback related to the mispronunciation of the word to the language learner.

摘要翻译： 存储表示要由处理器执行的指令的代码的非暂时处理器可读介质包括代码，以使处理器响应于语言学习者的提示而接收表示语言学习者用非母语表达的话语的声学数据 用非母语背诵单词，并以非母语接收单词的发音词典。 发音词典包括基于语言学习者的母语的发音词典的单词的至少一个替代发音。 该代码使得处理器基于非原生语言的至少一个替代发音生成声学模型，并且基于声学数据与声学模型的比较来识别话语中的单词的错误发音。 该代码使处理器发送与语言学习者错误地发音相关的反馈。
