  Real-time captioning is a useful technique for deaf and hard-of-hearing (DHH)
people to talk to hearing people. With the improvement in device performance
and the accuracy of automatic speech recognition (ASR), real-time captioning is
becoming an important tool for helping DHH people in their daily lives. To
realize higher-quality communication and overcome the limitations of mobile and
augmented-reality devices, real-time captioning that can be used comfortably
while maintaining nonverbal communication and preventing incorrect recognition
is required. Therefore, we propose a real-time captioning system that uses a
transparent display. In this system, the captions are presented on both sides
of the display to address the problem of incorrect ASR, and the highly
transparent display makes it possible to see both the body language and the
captions.
