Similarity Analysis between Scarlett Johansson and ChatGPT

Voice analysis reveals a remarkable resemblance between actress Scarlett Johansson and the now-pulled 'Sky' personal assistant developed by OpenAI. The analysis was conducted by researchers at Arizona State University, who compared Johansson's voice to Sky using AI models. The study found that Johansson's voice is more similar to Sky than 98% of other professional actresses. However, other Hollywood stars like Anne Hathaway and Keri Russell also showed similarities with the AI voice in question. The analysis highlighted both commonalities and differences between the voices of Sky and Johansson, indicating subtle distinctions in vocal features and expression.One of the key findings was that Sky's voice had a slightly higher pitch compared to Johansson's. Additionally, the study revealed differences in expressiveness and breathiness between the two voices. Despite these variations, the researchers noted distinct parallels, including identical vocal tract lengths. The debate over whether the similarity was intentional or coincidental sparked discussions about OpenAI's design choices and the implications of AI voices resembling famous personalities. In response to the controversy, OpenAI paused the Sky voice and clarified that it was not meant to mimic Johansson. The company emphasized that the AI voice was developed independently and was not based on any specific individual. However, Johansson expressed her concerns over the resemblance, revealing that OpenAI had approached her for licensing her voice for ChatGPT. She declined the offer, citing personal reasons. The situation raised questions about the ethics of using celebrity voices in AI technology and the potential implications for privacy and safety.
