Phoneme- vs. Character-Level Targets and Selective State-Space Models for Intracortical Brain-to-Text
Lucas Zamora Vera, Jose A. Gonzalez-Lopez
State-of-the-art intracortical brain-to-text systems pair a neural-sequence phone decoder with an external language model. Two design axes remain underexplored: whether selective s…
Zero-Shot Face-to-Speech Synthesis via Latent Space Adaptation of a Style-Diffusion TTS Model
Carlos Muñoz-Romero, Jose A. Gonzalez-Lopez
Zero-shot text-to-speech (TTS) clones a voice from a short audio prompt, but this reliance on reference audio is a barrier when only visual information is available, e.g. for histo…
End-to-End Intracortical Speech Decoding from Neural Activity
Owais Mujtaba Khanday, Jose A. Gonzalez-Lopez, Marc Ouellet +2
Current high-performing intracortical speech neuroprostheses achieve low word error rates but typically rely on external language models during inference, increasing memory, comput…
Recreating Neural Activity During Speech Production with Language and Speech Model Embeddings
Owais Mujtaba Khanday, Pablo Rodroguez San Esteban, Zubair Ahmad Lone +2
Understanding how neural activity encodes speech and language production is a fundamental challenge in neuroscience and artificial intelligence. This study investigates whether emb…
NeuroIncept Decoder for High-Fidelity Speech Reconstruction from Neural Activity
Owais Mujtaba Khanday, José L. Pérez-Córdoba, Mohd Yaqub Mir +2
This paper introduces a novel algorithm designed for speech synthesis from neural activity recordings obtained using invasive electroencephalography (EEG) techniques. The proposed…
Adversarial Transformation of Spoofing Attacks for Voice Biometrics
Alejandro Gomez-Alanis, Jose A. Gonzalez-Lopez, Antonio M. Peinado
Voice biometric systems based on automatic speaker verification (ASV) are exposed to \textit{spoofing} attacks which may compromise their security. To increase the robustness again…
PANACEA cough sound-based diagnosis of COVID-19 for the DiCOVA 2021 Challenge
Madhu R. Kamble, Jose A. Gonzalez-Lopez, Teresa Grau +11
The COVID-19 pandemic has led to the saturation of public health services worldwide. In this scenario, the early diagnosis of SARS-Cov-2 infections can help to stop or slow the spr…
Silent Speech Interfaces for Speech Restoration: A Review
Jose A. Gonzalez-Lopez, Alejandro Gomez-Alanis, Juan M. Martín-Doñas +2
This review summarises the status of silent speech interface (SSI) research. SSIs rely on non-acoustic biosignals generated by the human body during speech production to enable com…
Robust Binaural Localization of a Target Sound Source by Combining Spectral Source Models and Deep Neural Networks
Ning Ma, Jose A. Gonzalez, Guy J. Brown
Despite there being clear evidence for top-down (e.g., attentional) effects in biological spatial hearing, relatively few machine hearing systems exploit top-down model-based knowl…
Whispered-to-voiced Alaryngeal Speech Conversion with Generative Adversarial Networks
Santiago Pascual, Antonio Bonafonte, Joan Serrà +1
Most methods of voice restoration for patients suffering from aphonia either produce whispered or monotone speech. Apart from intelligibility, this type of speech lacks expressiven…
