Target Speech Extraction with Pre-trained Self-supervised Learning Models

no code implementations17 Feb 2024 Junyi Peng, Marc Delcroix, Tsubasa Ochiai, Oldrich Plchot, Shoko Araki, Jan Cernocky

We then extend a powerful TSE architecture by incorporating two SSL-based modules: an Adaptive Input Enhancer (AIE) and a speaker encoder.

Probing Self-supervised Learning Models with Target Speech Extraction

no code implementations17 Feb 2024 Junyi Peng, Marc Delcroix, Tsubasa Ochiai, Oldrich Plchot, Takanori Ashihara, Shoko Araki, Jan Cernocky

TSE uniquely requires both speaker identification and speech separation, distinguishing it from other tasks in the Speech processing Universal PERformance Benchmark (SUPERB) evaluation.

DiaCorrect: Error Correction Back-end For Speaker Diarization

1 code implementation15 Sep 2023 Jiangyu Han, Federico Landini, Johan Rohdin, Mireia Diez, Lukas Burget, Yuhang Cao, Heng Lu, Jan Cernocky

In this work, we propose an error correction framework, named DiaCorrect, to refine the output of a diarization system in a simple yet effective way.

End-to-End Open Vocabulary Keyword Search With Multilingual Neural Representations

no code implementations15 Aug 2023 Bolaji Yusuf, Jan Cernocky, Murat Saraclar

Conventional keyword search systems operate on automatic speech recognition (ASR) outputs, which causes them to have a complex indexing and search pipeline.

Extracting speaker and emotion information from self-supervised speech models via channel-wise correlations

no code implementations15 Oct 2022 Themos Stafylakis, Ladislav Mosner, Sofoklis Kakouros, Oldrich Plchot, Lukas Burget, Jan Cernocky

Self-supervised learning of speech representations from large amounts of unlabeled data has enabled state-of-the-art results in several speech processing tasks.

DPCCN: Densely-Connected Pyramid Complex Convolutional Network for Robust Speech Separation And Extraction

1 code implementation27 Dec 2021 Jiangyu Han, Yanhua Long, Lukas Burget, Jan Cernocky

Particularly, we find that the Mixture-Remix fine-tuning with DPCCN significantly outperforms the TD-SpeakerBeam for unsupervised cross-domain TSE, with around 3. 5 dB SISNR improvement on target domain test set, without any source domain performance degradation.

A Hierarchical Subspace Model for Language-Attuned Acoustic Unit Discovery

no code implementations4 Nov 2020 Bolaji Yusuf, Lucas Ondel, Lukas Burget, Jan Cernocky, Murat Saraclar

In the target language, we infer both the language and unit embeddings in an unsupervised manner, and in so doing, we simultaneously learn a subspace of units specific to that language and the units that dwell on it.

A Technical Report: BUT Speech Translation Systems

no code implementations22 Oct 2020 Hari Krishna Vydana, Lukas Burget, Jan Cernocky

To reduce this performance degradation, we have jointly-trained ASR and MT modules with ASR objective as an auxiliary loss.

Spoken Pass-Phrase Verification in the i-vector Space

no code implementations28 Sep 2018 Hossein Zeinali, Lukas Burget, Hossein Sameti, Jan Cernocky

The task of spoken pass-phrase verification is to decide whether a test utterance contains the same phrase as given enrollment utterances.
