Counting Closures in Spanish Trills: A Multi-Corpus Acoustic Study
Mateo Cámara, Maria F. Alcala-Durand
The Spanish trill /r/ is canonically described as a short sequence of lingual closures, yet large-scale acoustic evidence across corpora is scarce, and automatic counters locating…
Word Lengthening as a Function of Utterance Position: A Multi-Corpus Study
Mateo Cámara, José Luis Blanco, Juan Ignacio Godino-Llorente +2
Efficient turn-taking requires interlocutors to predict turn endings within a few hundred milliseconds. Beyond syntactic and pragmatic completion, prosody (especially pre-boundary…
Acoustic Landmark Detector based on Conformer and HuBERT
Mateo Cámara, José Luis Blanco, Juan Ignacio Godino-Llorente +2
Acoustic landmarks (abrupt acoustic changes tied to speech events) offer a linguistically grounded representation for speech analysis. We study automatic landmark detection with Co…
An Acoustic Landmark Database of the English Lexicon via Articulatory Synthesis
Mateo Cámara, José Luis Blanco, Juan Ignacio Godino-Llorente +2
Acoustic landmark theory treats speech as organized around the acoustic consequences of articulatory gestures that shape the vocal tract and airflow. Progress is limited by the sca…
A DDSP Framework for Adaptive Room Equalization
F. Marcos-Macias, M. P. Daza-Llin, M. Camara +1
Adaptive room equalization remains challenging under time-varying acoustic conditions and complex excitation signals, such as music. In these scenarios, classical filtered-x least…
Differentiable Articulatory Copy-Synthesis of Biphonic Singing
Mateo Cámara, María Pilar Daza-Llin, Fernando Marcos-Macías +1
Sygyt is a Tuvan style of biphonic singing in which a low vocal drone is sustained while a high harmonic is selectively amplified in the 1--3\,kHz region. Copy-synthesizing this ef…
Perceptually Equivalent Resolution in Handheld Devices for Streaming Bandwidth Saving
Mateo Cámara, César Díaz, Juan Casal +2
We present the description, results, and analysis of the experiments conducted to find the equivalent resolution associated with handheld devices. That is, the resolution from whic…
Vocal Tract Area Estimation by Gradient Descent
David Südholt, Mateo Cámara, Zhiyuan Xu +1
Articulatory features can provide interpretable and flexible controls for the synthesis of human vocalizations by allowing the user to directly modify parameters like vocal strain…
