However, most work done in dubbing mistakes is done in post-production which is often not applicable to live broadcasts. This project aims to develop a real-time voice correction system that automatically detects and corrects speech errors in near real-time while integrating the adjusted audio into ongoing conversations without disrupting the natural flow. This paper utilizes various AI tools like the Nous Hermes 2-Mistral 7B DPO large language model to first generate the reference script for Coqui's XTTS-V2 zero-shot text-to-speech voice cloning model. After the correction is generated, it goes through a series of filters to replace the mistake and seamlessly integrates it. The experiment's user survey demonstrates that the corrected audio is of high quality.","doi":"10.24963/ijcai.2025/1253","url":"https://ijcai.org/proceedings/2025/1253","pdf":"https://ijcai.org/proceedings/2025/1253.pdf","markdown":"https://ijcai.org/proceedings/2025/1253.md","bibtex":"https://ijcai.org/proceedings/2025/bibtex/1253","volume":{"slug":"2025","title":"Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2025","url":"https://ijcai.org/proceedings/2025/","year":2025,"location":"Montreal, Canada","dates":"16-22 August 2025","editors":"James Kwok","isbn":"978-1-956792-06-5","publisher":"International Joint Conferences on Artificial Intelligence Organization","doi_prefix":"10.24963/ijcai.2025"},"section":"Demo Track","track":"Demo Track","number":1253,"pages":{"first":11017,"last":11020},"keywords":["Humans and AI: HAI: Intelligent user interfaces","Humans and AI: HAI: Applications"],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
