TokAN: Accent Normalization Using Self-Supervised Speech Tokens

Qibing Bai, Shuai Wang, Yuhan Du +3

Accent normalization (AN) seeks to convert non-native (L2) accented speech into standard (L1) speech while preserving speaker identity. The current techniques either require natura…

PhiNet: Speaker Verification with Phonetic Interpretability

Yi Ma, Shuai Wang, Tianchi Liu +1

Despite remarkable progress, automatic speaker verification (ASV) systems typically lack the transparency required for high-accountability applications. Motivated by how human expe…

Borderless Long Speech Synthesis

Xingchen Song, Di Wu, Dinghao Zhou +12

Most existing text-to-speech (TTS) systems either synthesize speech sentence by sentence and stitch the results together, or drive synthesis from plain-text dialogues alone. Both a…

AlphaFlowTSE: One-Step Generative Target Speaker Extraction via Conditional AlphaFlow

Duojia Li, Shuhan Zhang, Zihan Qian +5

In target speaker extraction (TSE), we aim to recover target speech from a multi-talker mixture using a short enrollment utterance as reference. Recent studies on diffusion and flo…

Controllable Accent Normalization via Discrete Diffusion

Qibing Bai, Yuhan Du, Tom Ko +3

Existing accent normalization methods do not typically offer control over accent strength, yet many applications-such as language learning and dubbing-require tunable accent retent…

G-STAR: End-to-End Global Speaker-Tracking Attributed Recognition

Jing Peng, Ziyi Chen, Haoyu Li +7

We study timestamped speaker-attributed automatic speech recognition (SA-ASR) for long-form, multi-party speech with overlap. In this setting, chunk-wise inference must preserve me…

CosyAccent: Duration-Controllable Accent Normalization Using Source-Synthesis Training Data

Qibing Bai, Shuhao Shi, Shuai Wang +3

Accent normalization (AN) systems often struggle with unnatural outputs and undesired content distortion, stemming from both suboptimal training data and rigid duration modeling. I…

Direct Preference Optimization for Speech Autoregressive Diffusion Models

Zhijun Liu, Dongya Jia, Xiaoqiang Wang +4

Autoregressive diffusion models (ARDMs) have recently been applied to speech generation, achieving state-of-the-art (SOTA) performance in zero-shot text-to-speech. By autoregressiv…

Accent Normalization Using Self-Supervised Discrete Tokens with Non-Parallel Data

Qibing Bai, Sho Inoue, Shuai Wang +3

Accent normalization converts foreign-accented speech into native-like speech while preserving speaker identity. We propose a novel pipeline using self-supervised discrete tokens a…

SpeechRefiner: Towards Perceptual Quality Refinement for Front-End Algorithms

Sirui Li, Shuai Wang, Zhijun Liu +3

Speech pre-processing techniques such as denoising, de-reverberation, and separation, are commonly employed as front-ends for various downstream speech processing tasks. However, t…

Causal Self-supervised Pretrained Frontend with Predictive Code for Speech Separation

Wupeng Wang, Zexu Pan, Xinke Li +2

Speech separation (SS) seeks to disentangle a multi-talker speech mixture into single-talker speech streams. Although SS can be generally achieved using offline methods, such a pro…

Context-Aware Two-Step Training Scheme for Domain Invariant Speech Separation

Wupeng Wang, Zexu Pan, Jingru Lin +2

Speech separation seeks to isolate individual speech signals from a multi-talk speech mixture. Despite much progress, a system well-trained on synthetic data often experiences perf…

ExPO: Explainable Phonetic Trait-Oriented Network for Speaker Verification

Yi Ma, Shuai Wang, Tianchi Liu +1

In speaker verification, we use computational method to verify if an utterance matches the identity of an enrolled speaker. This task is similar to the manual task of forensic voic…
