Publication number: 20180039625Abstract: A translation device includes an input unit, a controller, a notification unit, an output unit, and a memory. The input unit inputs an utterance of a speaker to generate utterance data. The controller determines accuracy of a translation result when translated utterance data from the utterance data is obtained. The notification unit notifies the speaker of the determination result of the controller. The output unit outputs a translated utterance according to the translated utterance data. The memory stores dictionary data associating utterance data with translated utterance data. The controller performs translation based on the dictionary data. When the controller determines that the accuracy of the translation result is lower than a predetermined value, the controller controls the output unit not to output the translated utterance, and controls the notification unit to issue a notification regarding the determination result.Type: ApplicationFiled: October 3, 2017Publication date: February 8, 2018Inventors: Takayuki HAYASHI, Tomokazu ISHIKAWA
