StreamVoice: Streamable Context-Aware Language Modeling for Real-time Zero-Shot Voice Conversion

no code implementations19 Jan 2024 Zhichao Wang, Yuanzhe Chen, Xinsheng Wang, Zhuo Chen, Lei Xie, Yuping Wang, Yuxuan Wang

Specifically, to enable streaming capability, StreamVoice employs a fully causal context-aware LM with a temporal-independent acoustic predictor, while alternately processing semantic and acoustic features at each time step of autoregression which eliminates the dependence on complete source speech.

LM-VC: Zero-shot Voice Conversion via Speech Generation based on Language Models

no code implementations18 Jun 2023 Zhichao Wang, Yuanzhe Chen, Lei Xie, Qiao Tian, Yuping Wang

An intuitive approach is to follow AudioLM - Tokenizing speech into semantic and acoustic tokens respectively by HuBERT and SoundStream, and converting source semantic tokens to target acoustic tokens conditioned on acoustic tokens of the target speaker.

Multi-level Temporal-channel Speaker Retrieval for Zero-shot Voice Conversion

no code implementations12 May 2023 Zhichao Wang, Liumeng Xue, Qiuqiang Kong, Lei Xie, Yuanzhe Chen, Qiao Tian, Yuping Wang

Specifically, to flexibly adapt to the dynamic-variant speaker characteristic in the temporal and channel axis of the speech, we propose a novel fine-grained speaker modeling method, called temporal-channel retrieval (TCR), to find out when and where speaker information appears in speech.

Zero-Shot Accent Conversion using Pseudo Siamese Disentanglement Network

no code implementations12 Dec 2022 Dongya Jia, Qiao Tian, Kainan Peng, Jiaxin Li, Yuanzhe Chen, Mingbo Ma, Yuping Wang, Yuxuan Wang

The goal of accent conversion (AC) is to convert the accent of speech into the target accent while preserving the content and speaker identity.

Delivering Speaking Style in Low-resource Voice Conversion with Multi-factor Constraints

no code implementations16 Nov 2022 Zhichao Wang, Xinsheng Wang, Lei Xie, Yuanzhe Chen, Qiao Tian, Yuping Wang

Conveying the linguistic content and maintaining the source speech's speaking style, such as intonation and emotion, is essential in voice conversion (VC).

Understanding Hidden Memories of Recurrent Neural Networks

1 code implementation30 Oct 2017 Yao Ming, Shaozu Cao, Ruixiang Zhang, Zhen Li, Yuanzhe Chen, Yangqiu Song, Huamin Qu

We propose a technique to explain the function of individual hidden state units based on their expected response to input texts.

A new network-based algorithm for human activity recognition in video

no code implementations21 Feb 2015 Weiyao Lin, Yuanzhe Chen, Jianxin Wu, Hanli Wang, Bin Sheng, Hongxiang Li

Based on this network, we further model people in the scene as packages while human activities can be modeled as the process of package transmission in the network.

Intra-and-Inter-Constraint-based Video Enhancement based on Piecewise Tone Mapping

no code implementations21 Feb 2015 Yuanzhe Chen, Weiyao Lin, Chongyang Zhang, Zhenzhong Chen, Ning Xu, Jun Xie

In this paper, we propose a new intra-and-inter-constraint-based video enhancement approach aiming to 1) achieve high intra-frame quality of the entire picture where multiple region-of-interests (ROIs) can be adaptively and simultaneously enhanced, and 2) guarantee the inter-frame quality consistencies among video frames.
