Compact Speech Translation Models via Discrete Speech Units Pretraining

no code implementations29 Feb 2024 Tsz Kin Lam, Alexandra Birch, Barry Haddow

In this paper, we leverage the SSL models by pretraining smaller models on their Discrete Speech Units (DSU).

Prosody in Cascade and Direct Speech-to-Text Translation: a case study on Korean Wh-Phrases

no code implementations1 Feb 2024 Giulio Zhou, Tsz Kin Lam, Alexandra Birch, Barry Haddow

While there has been a growing interest in developing direct speech translation systems to avoid propagating errors and losing non-verbal content, prior work in direct S2TT has struggled to conclusively establish the advantages of integrating the acoustic signal directly into the translation process.

On-the-Fly Aligned Data Augmentation for Sequence-to-Sequence ASR

1 code implementation3 Apr 2021 Tsz Kin Lam, Mayumi Ohta, Shigehiko Schamoni, Stefan Riezler

Our method, called Aligned Data Augmentation (ADA) for ASR, replaces transcribed tokens and the speech representations in an aligned manner to generate previously unseen training pairs.

Interactive-Predictive Neural Machine Translation through Reinforcement and Imitation

no code implementations WS 2019 Tsz Kin Lam, Shigehiko Schamoni, Stefan Riezler

We propose an interactive-predictive neural machine translation framework for easier model personalization using reinforcement and imitation learning.

A Reinforcement Learning Approach to Interactive-Predictive Neural Machine Translation

1 code implementation3 May 2018 Tsz Kin Lam, Julia Kreutzer, Stefan Riezler

We present an approach to interactive-predictive neural machine translation that attempts to reduce human effort from three directions: Firstly, instead of requiring humans to select, correct, or delete segments, we employ the idea of learning from human reinforcements in form of judgments on the quality of partial translations.
