Speech enabled visual acuity test

This paper introduces a novel automatic visual acuity test system employing automatic speech recognition and image recognition. The system provides users a private and self-paced eye assessment experience. During such visual acuity test, the system communicates with user via speech interaction: the system prompts user to speak out the letters shown and recognizes user’s speech input to assess user’s eye sights. The system is also able to automatically detect user’s posture and notify user when incorrect posture is detected. When the testing process is completed, the system will analyze the result automatically and record the details in database.
