Data Augmentation for Low-Resource Quechua ASR Improvement

no code implementations14 Jul 2022 Rodolfo Zevallos, Nuria Bel, Guillermo Cámbara, Mireia Farrús, Jordi Luque

In this paper we describe our data augmentation approach to improve the results of ASR models for low-resource and agglutinative languages.

Voice Quality and Pitch Features in Transformer-Based Speech Recognition

no code implementations21 Dec 2021 Guillermo Cámbara, Jordi Luque, Mireia Farrús

Jitter and shimmer measurements have shown to be carriers of voice quality and prosodic information which enhance the performance of tasks like speaker recognition, diarization or automatic speech recognition (ASR).

Influence of ASR and Language Model on Alzheimer's Disease Detection

no code implementations20 Sep 2021 Joan Codina-Filbà, Guillermo Cámbara, Jordi Luque, Mireia Farrús

Furthermore, we study the influence of a language model -- which tends to correct non-standard sequences of words -- with the lack of language model to decode the hypothesis from the ASR.

English Accent Accuracy Analysis in a State-of-the-Art Automatic Speech Recognition System

no code implementations9 May 2021 Guillermo Cámbara, Alex Peiró-Lilja, Mireia Farrús, Jordi Luque

Nowadays, research in speech technologies has gotten a lot out thanks to recently created public domain corpora that contain thousands of recording hours.

Efficient Keyword Spotting by capturing long-range interactions with Temporal Lambda Networks

1 code implementation16 Apr 2021 Biel Tura, Santiago Escuder, Ferran Diego, Carlos Segura, Jordi Luque

This work explores the application of Lambda networks, an alternative framework for capturing long-range interactions without attention, for the keyword spotting task.

Convolutional Speech Recognition with Pitch and Voice Quality Features

no code implementations2 Sep 2020 Guillermo Cámbara, Jordi Luque, Mireia Farrús

Up to our knowledge, this is the first work combining such pitch and voice quality features with modern convolutional architectures, showing improvements up to 7% and 3% relative WER points, for the publicly available Spanish Common Voice and LibriSpeech 100h datasets, respectively.

Transcription-Enriched Joint Embeddings for Spoken Descriptions of Images and Videos

no code implementations1 Jun 2020 Benet Oriol, Jordi Luque, Ferran Diego, Xavier Giro-i-Nieto

In this work, we propose an effective approach for training unique embedding representations by combining three simultaneous modalities: image and spoken and textual narratives.

Detection of speech events and speaker characteristics through photo-plethysmographic signal neural processing

no code implementations12 Nov 2019 Guillermo Cámbara, Jordi Luque, Mireia Farrús

The use of photoplethysmogram signal (PPG) for heart and sleep monitoring is commonly found nowadays in smartphones and wrist wearables.

Input complexity and out-of-distribution detection with likelihood-based generative models

2 code implementations ICLR 2020 Joan Serrà, David Álvarez, Vicenç Gómez, Olga Slizovskaia, José F. Núñez, Jordi Luque

Likelihood-based generative models are a promising resource to detect out-of-distribution (OOD) inputs which could compromise the robustness or reliability of a machine learning system.

Emergence of linguistic laws in human voice

no code implementations9 Oct 2016 Ivan Gonzalez Torre, Bartolo Luque, Lucas Lacasa, Jordi Luque, Antoni Hernandez-Fernandez

This means that inferences of statistical patterns of language in acoustics are biased by the arbitrary, language-dependent segmentation of the signal, and virtually precludes the possibility of making comparative studies between human voice and other animal communication systems.

Speech earthquakes: scaling and universality in human voice

no code implementations5 Aug 2014 Jordi Luque, Bartolo Luque, Lucas Lacasa

We first show that during speech the energy is unevenly released and power-law distributed, reporting a universal robust Gutenberg-Richter-like law in speech.
