While voice assistants like Siri, Alexa, or Google Assistant can be useful for various voice-based functions, there are times when you need to perform some tasks without disturbing others in, say, a library or quiet zone in the office. So, to help users silently deliver voice commands to smart devices, two Cornell University researchers developed a silent-speech recognition wearable camera. Let’s take a look at the details.
Cheng Zhang, an assistant professor of information science at Cornell University’s Ann S. Bowers College of Computing and Information Science, and Ruidong Zhang, a doctoral student at the same university developed the special silent speech recognition camera.
The researchers say that the silent-speech recognition camera can recognize 54 English phrases and general voice commands, and 44 words and phrases in Mandarin Chinese. They tested SpeeChin with 20 participants, and the device was able to deliver a 90.5% of accuracy rate when recognizing the English commands and a 91.6% of accuracy rate when recognizing Chinese commands. But, the accuracy rates fell when the participants moved while giving silent commands to the camera.
