The Significance of Artificial Intelligence in Speech and Facial Recognition
Introduction
Artificial Intelligence (AI) has become increasingly important in speech and facial recognition technology. By recording and synthesizing brain signals associated with speech and facial expressions, AI has enabled remarkable advancements in these areas. Additionally, AI has the ability to encode and decode these signals at a rapid rate, further enhancing the capabilities of the system. While these techniques are still relatively new, AI has already produced impressive results in speech recognition, particularly for individuals with paralysis.
UC San Francisco and UC Berkeley’s Brain-Computer Interface
Researchers from UC San Francisco and UC Berkeley have developed a Brain-Computer Interface, also known as a smart brain. This interface establishes a direct communication pathway between the brain’s electrical impulses and an external device, such as a robot or AI chatbot. This breakthrough technology has allowed individuals with paralysis to communicate using a digital avatar. The goal of the researchers is to create a seamless and natural way for people to communicate. By implementing a rectangle-shaped electrode on the surface of the individual’s body, the researchers were able to capture and interpret her brain signals, improving the accuracy of speech recognition. They trained the AI model using various techniques, including the bag-of-words model in Natural Language Processing, which helped recognize and encode words into phonemes. As a result, the system became more accurate and faster than before.
Voice Generation and Face Recognition
In their study, the researchers developed an algorithm to generate the woman’s voice using her recorded voice from her wedding. Although the initial output had some defects, the researchers were able to improve the quality of the generated voice. They also created a Digital Avatar that assisted with the woman’s facial recognition. A Machine Learning model was developed to merge the Avatar with the woman’s brain signals, capturing every movement of her jaw, lips, tongue, mouth, and other facial features.
The Future of the Technology
The researchers are currently working on developing a wireless connection between the human body and the software, which would be the next version of this model. This wireless setup would offer the advantage of non-direct contact. Ongoing work involves refining various Deep Learning algorithms and conducting hyperparameter testing to improve the efficiency of the model.
