Speaker activity driven neural speech extraction

no code implementations14 Jan 2021 Marc Delcroix, Katerina Zmolikova, Tsubasa Ochiai, Keisuke Kinoshita, Tomohiro Nakatani

Target speech extraction, which extracts the speech of a target speaker in a mixture given auxiliary speaker clues, has recently received increased interest.

Integration of variational autoencoder and spatial clustering for adaptive multi-channel neural speech separation

1 code implementation24 Nov 2020 Katerina Zmolikova, Marc Delcroix, Lukáš Burget, Tomohiro Nakatani, Jan "Honza" Černocký

In this paper, we propose a method combining variational autoencoder model of speech with a spatial clustering approach for multi-channel speech separation.

Jointly Trained Transformers models for Spoken Language Translation

no code implementations25 Apr 2020 Hari Krishna Vydana, Martin Karafi'at, Katerina Zmolikova, Luk'as Burget, Honza Cernocky

Conventional spoken language translation (SLT) systems are pipeline based systems, where we have an Automatic Speech Recognition (ASR) system to convert the modality of source from speech to text and a Machine Translation (MT) systems to translate source text to text in target language.

Improving speaker discrimination of target speech extraction with time-domain SpeakerBeam

1 code implementation23 Jan 2020 Marc Delcroix, Tsubasa Ochiai, Katerina Zmolikova, Keisuke Kinoshita, Naohiro Tawara, Tomohiro Nakatani, Shoko Araki

First, we propose a time-domain implementation of SpeakerBeam similar to that proposed for a time-domain audio separation network (TasNet), which has achieved state-of-the-art performance for speech separation.
