5. A language data storage and reproduction apparatus comprising: a language data inputting section for inputting an electric signal string representative of language data; a data recognition section for producing a plurality of recognition data sets, wherein each recognition data set corresponds to a portion of said electric signal string, and each recognition data set contains a plurality of candidates for recognizing said language data, wherein each of the candidates of one recognition data set corresponds to the same portion of said electric signal string as the other candidates in said one recognition data set, and wherein each of the candidates of said one recognition data set is different from any other candidate in said one recognition data set; a storage section for storing each recognition data set together with the corresponding portion of said electric signal string; an inputting section for inputting a desired word or phrase to be retrieved; a retrieval section for comparing the desired word or phrase to said plurality of candidates in said recognition data sets, and for retrieving the recognition data set which contains the candidate most closely matched to the desired word or phrase; a reproduction section for reproducing the segment of language data which corresponds to the recognition data set retrieved by the retrieval section.
