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.

Super-Human Performance in Online Low-latency Recognition of Conversational Speech

1 code implementation7 Oct 2020 Thai-Son Nguyen, Sebastian Stueker, Alex Waibel

Achieving super-human performance in recognizing human speech has been a goal for several decades, as researchers have worked on increasingly challenging tasks.

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.

Learning Shared Encoding Representation for End-to-End Speech Recognition Models

no code implementations31 Mar 2019 Thai-Son Nguyen, Sebastian Stueker, Alex Waibel

In this work, we learn a shared encoding representation for a multi-task neural network model optimized with connectionist temporal classification (CTC) and conventional framewise cross-entropy training criteria.

Using multi-task learning to improve the performance of acoustic-to-word and conventional hybrid models

no code implementations2 Feb 2019 Thai-Son Nguyen, Sebastian Stueker, Alex Waibel

Acoustic-to-word (A2W) models that allow direct mapping from acoustic signals to word sequences are an appealing approach to end-to-end automatic speech recognition due to their simplicity.
