Abstract
This paper introduces a support system for inputting electronic medical records based on the automatic voice recognition. The system is being constructed by the combination of an electronic medical record that has the ontology-based structure, and a voice recognition engine, and is expected to work in the actual environment. In our previous study, we found that environmental noises caused the failure of the voice recognition, and resulted in the low recognition rate to some subjects. In this study, a recognition experiment was conducted to examine the influence of an acoustic noise in a real situation. Environmental noises were recorded in a medical clinic, which were used in the voice recognition experiment. We found that the noise greater than 20 [dB] in the S/N ratio caused the failure of the voice recognition. In the future work, by employing a noise reduction technique in the voice input part, we further examine the recognition ability.
