Generating Credible Sign Language Deepfakes: A Linguistic and Visual Analysis

Q: How can the generated sign language deepfake dataset be further utilized to improve deepfake detection models and protect the Deaf and Hard of Hearing (DHoH) community from potential misinformation?

The generated sign language deepfake dataset can serve as a valuable resource for enhancing deepfake detection models specifically tailored for sign language content. By using this dataset, researchers and developers can train machine learning algorithms to recognize patterns and discrepancies between real sign language videos and deepfake ones. This training can help in the creation of more robust deepfake detection systems that can identify fake sign language videos with higher accuracy. Moreover, the dataset can be used to develop specialized tools and technologies that focus on detecting deepfake videos targeting the Deaf and Hard of Hearing (DHoH) community. These tools can be integrated into platforms and services that provide sign language content to ensure the authenticity and credibility of the videos being shared. By implementing such detection mechanisms, the DHoH community can be safeguarded from potential misinformation and deceptive content that may harm their trust and understanding of sign language communication.

Q: What are the potential ethical concerns and societal implications of using deepfake technology, even for positive applications like sign language content creation?

While deepfake technology can have positive applications, such as creating sign language content for the Deaf and Hard of Hearing (DHoH) community, there are significant ethical concerns and societal implications that need to be considered. One major ethical concern is the potential misuse of deepfake technology to spread misinformation or manipulate individuals through fabricated content. In the context of sign language deepfakes, there is a risk of creating deceptive videos that could mislead viewers, especially those who rely on sign language for communication. From a societal perspective, the proliferation of deepfake technology, even for positive purposes, can erode trust and authenticity in digital content. It may lead to skepticism and doubt regarding the veracity of online videos, including sign language content. This could have detrimental effects on the DHoH community, as they rely on accurate and reliable sign language resources for communication and information. Additionally, there are concerns about consent and privacy when using deepfake technology, as individuals' identities can be manipulated without their permission. This raises questions about the ethical implications of creating deepfake videos, even for beneficial purposes like sign language content creation.

Q: How can this research on sign language deepfakes be extended to other forms of non-verbal communication, such as body language or facial expressions, to create more inclusive and accessible digital content?

The research on sign language deepfakes can be extended to other forms of non-verbal communication, such as body language or facial expressions, to enhance the inclusivity and accessibility of digital content. By applying similar deepfake generation techniques to body language and facial expressions, researchers can create realistic and expressive animations that convey emotions and messages effectively. One approach could involve developing datasets of body language and facial expression movements, similar to the sign language dataset created in the research. These datasets can be used to train models that generate authentic non-verbal communication cues in digital content. By incorporating diverse gestures, postures, and expressions, digital content creators can make their videos more engaging and relatable to a wider audience. Furthermore, the deepfake detection methods and techniques developed for sign language videos can be adapted to identify fake body language or facial expression content. This can help in ensuring the integrity and accuracy of non-verbal communication representations in digital media, promoting inclusivity and accessibility for individuals who rely on visual cues for understanding and interaction.

Core Concepts

This research presents a positive application of deepfake technology in generating visually and linguistically credible sign language videos, while also establishing a benchmark for deepfake detection in sign language.

Abstract

The research aims to extend deepfake technology beyond facial manipulation to generate credible sign language videos that encompass the entire upper body, including hands and fingers. The key highlights and insights are:

Construction of a reliable deepfake dataset with over 1200 videos, featuring both previously seen and unseen individuals for the generation model. This dataset was vetted by a sign language expert.
Linguistic analysis reveals that the generated fake videos are comparable to real sign language videos, with the interpretation of a fake being at least 90% the same as the real video.
Visual analysis demonstrates that visually convincing deepfake videos can be produced, even with entirely new subjects, using a pose/style transfer model for video generation.
Machine learning algorithms were applied to establish a baseline performance on the dataset for deepfake detection, highlighting the challenges in accurately classifying real and fake sign language videos.
The sign language expert exhibited confusion in identifying the real from fake videos, further validating the credibility of the generated deepfakes.
The research makes a pioneering contribution to accelerate work in the sign language production domain and create videos that are visually believable and technically & linguistically credible to human perception.

Quotes

"Our research aims to extend the deepfakes beyond just the facial elements, aiming to create fake videos that encompass the upper body as well, while addressing elements such as the hands and fingers for sign language production."
"Deepfakes pose new challenges such as fake news, rumour propagation, and several ethical concerns. Due to these reasons there have been several algorithms that target deepfake detection [16], [17], [18]. However, none of the aforementioned works focused on sign-language deepfake detection."
