KIT’s Multilingual Neural Machine Translation systems for IWSLT 2017

no code implementations IWSLT 2017 Ngoc-Quan Pham, Matthias Sperber, Elizabeth Salesky, Thanh-Le Ha, Jan Niehues, Alexander Waibel

For the SLT track, in addition to a monolingual neural translation system used to generate correct punctuations and true cases of the data prior to training our multilingual system, we introduced a noise model in order to make our system more robust.

Efficient Weight factorization for Multilingual Speech Recognition

no code implementations7 May 2021 Ngoc-Quan Pham, Tuan-Nam Nguyen, Sebastian Stueker, Alexander Waibel

The key idea of the method is to assign fast weight matrices for each language by decomposing each weight matrix into a shared component and a language dependent component.

Relative Positional Encoding for Speech Recognition and Direct Translation

no code implementations20 May 2020 Ngoc-Quan Pham, Thanh-Le Ha, Tuan-Nam Nguyen, Thai-Son Nguyen, Elizabeth Salesky, Sebastian Stueker, Jan Niehues, Alexander Waibel

We also show that this model is able to better utilize synthetic data than the Transformer, and adapts better to variable sentence segmentation quality for speech translation.

High Performance Sequence-to-Sequence Model for Streaming Speech Recognition

no code implementations22 Mar 2020 Thai-Son Nguyen, Ngoc-Quan Pham, Sebastian Stueker, Alex Waibel

However, when it comes to performing run-on recognition on an input stream of audio data while producing recognition results in real-time and with low word-based latency, these models face several challenges.

Self-Attentional Models for Lattice Inputs

no code implementations ACL 2019 Matthias Sperber, Graham Neubig, Ngoc-Quan Pham, Alex Waibel

Lattices are an efficient and effective method to encode ambiguity of upstream systems in natural language processing tasks, for example to compactly capture multiple speech recognition hypotheses, or to represent multiple linguistic analyses.

Low-Latency Neural Speech Translation

no code implementations1 Aug 2018 Jan Niehues, Ngoc-Quan Pham, Thanh-Le Ha, Matthias Sperber, Alex Waibel

After adaptation, we are able to reduce the number of corrections displayed during incremental output construction by 45%, without a decrease in translation quality.
