• A Japanese text input system by speech that is uttered character by character is described. The system mainly consists of an acoustic processing stage and a linguistic processing stage. Acoustic processing is carried out through speech analysis based on linear prediction, segmentation of input speech into syllable strings and syllable recognition based on a dynamic programming method. Translation of syllable recognition results into Japanese text is done by the processes of word candidate retrieval and word ranking through the use of a Kanji-Kana word dictionary and grammatical rules. To cover for segmentation errors which occur due to inadequate handling in coarticulation, two kinds of error correction algorithms are adopted: One being syllable boundary correction by phonemic distortion rules in the acoustic processing stage and the other being recognition result revision in the linguistic processing stage. The system was tested by running it through acoustic and linguistic processing experiments using a Japanese text uttered by five speakers. A syllable recognition rate of 86. 7% and a Japanese translation rate of 83. 1% were obtained.
