Portable speech interpreter which has voice input and sophisticated correction functions

This paper describes the development of a portable speech interpreter by which the user can look for words and relating sentences easily using his/her voice. The prototype uses a RISC microprocessor for the embedded use, resulting in a compact body of 15cm(W) and 6cm(H). The voice user interface is helpful, especially in small devices, but it has a serious problem related to the recognition errors. The total user interface must be designed carefully to minimize the inconvenience caused by the recognition errors. We have developed an interface in which the confinement of the dictionary realizes the quick and accurate recognition, and the syllable correction procedure provides an easy way to correct recognition errors. These features make it possible to input any words, which are found in a standard Japanese dictionary. Experimental evaluations show that the N-best recognition rate for words and syllables are acceptable.
