Speaker Embeddings as Individuality Proxy for Voice Stress Detection

no code implementations9 Jun 2023 Zihan Wu, Neil Scheidwasser-Clow, Karl El Hajal, Milos Cernak

However, the benchmark only evaluates performance separately on each dataset, but does not evaluate performance across the different types of stress and different languages.

Efficient Speech Quality Assessment using Self-supervised Framewise Embeddings

no code implementations12 Nov 2022 Karl El Hajal, Zihan Wu, Neil Scheidwasser-Clow, Gasser Elbanna, Milos Cernak

Automatic speech quality assessment is essential for audio researchers, developers, speech and language pathologists, and system quality engineers.

BYOL-S: Learning Self-supervised Speech Representations by Bootstrapping

1 code implementation24 Jun 2022 Gasser Elbanna, Neil Scheidwasser-Clow, Mikolaj Kegler, Pierre Beckmann, Karl El Hajal, Milos Cernak

Our results indicate that the hybrid model with a convolutional transformer as the encoder yields superior performance in most HEAR challenge tasks.

MOSRA: Joint Mean Opinion Score and Room Acoustics Speech Quality Assessment

no code implementations4 Apr 2022 Karl El Hajal, Milos Cernak, Pablo Mainar

The acoustic environment can degrade speech quality during communication (e. g., video call, remote presentation, outside voice recording), and its impact is often unknown.

Neural Arabic Question Answering

1 code implementation WS 2019 Hussein Mozannar, Karl El Hajal, Elie Maamary, Hazem Hajj

Our system for open domain question answering in Arabic (SOQAL) is based on two components: (1) a document retriever using a hierarchical TF-IDF approach and (2) a neural reading comprehension model using the pre-trained bi-directional transformer BERT.
