Recycle Your Wav2Vec2 Codebook: A Speech Perceiver for Keyword Spotting

no code implementations COLING 2022 Guillermo Cámbara, Jordi Luque, Mireia Farrús

We do so by transferring the codebook as weights for the latent bottleneck of a Keyword Spotting Perceiver, thus initializing such model with phonetic embeddings already.

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.

Combining Prosodic, Voice Quality and Lexical Features to Automatically Detect Alzheimer's Disease

no code implementations18 Nov 2020 Mireia Farrús, Joan Codina-Filbà

Both tasks have been performed extracting 28 features from speech -- based on prosody and voice quality -- and 51 features from the transcriptions -- based on lexical and turn-taking information.

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.
