S-DiverSe: Spanish Diverse Speech

Fernando López, Fernando Ibañez, Ana Martínez +4

Automatic speech recognition (ASR) has advanced remarkably for standard speech, yet speech affected by neurological conditions remains a challenge. We present S-DiverSe (Spanish Di…

FiLM-Based Speaker Conditioning of a SpeechLLM for Pathological Speech Recognition

Fernando López, Santosh Kesiraju, Jordi Luque

Automatic speech recognition (ASR) has advanced remarkably for standard speech; however, pathological speech from neurological conditions remains a significant challenge. We invest…

FLiP: Towards understanding and interpreting multimodal multilingual sentence embeddings

Santosh Kesiraju, Bolaji Yusuf, Šimon Sedláček +2

This paper presents factorized linear projection (FLiP) models for understanding pretrained sentence embedding spaces. We train FLiP models to recover the lexical content from mult…

End-to-End Speech Translation for Low-Resource Languages Using Weakly Labeled Data

Aishwarya Pothula, Bhavana Akkiraju, Srihari Bandarupalli +3

The scarcity of high-quality annotated data presents a significant challenge in developing effective end-to-end speech-to-text translation (ST) systems, particularly for low-resour…

Factors affecting the in-context learning abilities of LLMs for dialogue state tracking

Pradyoth Hegde, Santosh Kesiraju, Jan Švec +5

This study explores the application of in-context learning (ICL) to the dialogue state tracking (DST) problem and investigates the factors that influence its effectiveness. We use…

Approaching Dialogue State Tracking via Aligning Speech Encoders and LLMs

Šimon Sedláček, Bolaji Yusuf, Ján Švec +4

In this work, we approach spoken Dialogue State Tracking (DST) by bridging the representation spaces of speech encoders and LLMs via a small connector module, with a focus on fully…

Aligning Pre-trained Models for Spoken Language Translation

Šimon Sedláček, Santosh Kesiraju, Alexander Polok +1

This paper investigates a novel approach to end-to-end speech translation (ST) based on aligning frozen pre-trained automatic speech recognition (ASR) and machine translation (MT)…

Improving Automatic Speech Recognition with Decoder-Centric Regularisation in Encoder-Decoder Models

Alexander Polok, Santosh Kesiraju, Karel Beneš +2

This paper proposes a simple yet effective way of regularising the encoder-decoder-based automatic speech recognition (ASR) models that enhance the robustness of the model and impr…

A Bayesian Multilingual Document Model for Zero-shot Topic Identification and Discovery

Santosh Kesiraju, Sangeet Sagar, Ondřej Glembek +3

In this paper, we present a Bayesian multilingual document model for learning language-independent document embeddings. The model is an extension of BaySMM [Kesiraju et al 2020] to…

An Empirical Evaluation of Zero Resource Acoustic Unit Discovery

Chunxi Liu, Jinyi Yang, Ming Sun +7

Acoustic unit discovery (AUD) is a process of automatically identifying a categorical acoustic unit inventory from speech and producing corresponding acoustic unit tokenizations. A…
