Title:

Automatic Video Dubbing Challenges and Solutions

Abstract:

Traditional Automatic Video Dubbing (AVD) pipeline consists of three key modules, namely, Automatic Speech Recognition (ASR), Neural Machine Translation (NMT), and Text-to-Speech (TTS). Guaranteeing synchronization with respect to the alignment of video and audio subsequent to the dubbing process is one of the most challenging research problems. Within AVD pipelines, isometric-NMT algorithms are employed to regulate the length of the synthesized output text. Previous approaches have focused on aligning the number of characters and words in the source and target language texts of Machine Translation models. However, our approach aims to align the number of phonemes instead, as they are closely associated with speech duration. This work has been published at NAACL 2024. Furthermore, we propose a novel method, Dub-Wise: Multi-modal Large Language Model (LLM)-based TTS, which can control the speech duration of synthesized speech in such a way that it aligns well with the speaker's lip movements given in the reference video even when the spoken text is different or in a different language. This work has been accepted in Interspeech 2024. Furthermore, TTS necessitates the extraction of voice identity and emotional style from a reference speech in a source language and subsequently transferring them to a target language using cross-lingual TTS techniques. To this end, we introduce an end-to-end Voice Identity and Emotional Style Controllable Cross-Lingual (VECL) TTS system using multilingual speakers and an emotion embedding network. This work has also been accepted in Interspeech 2024.
