Spectral Study of the Vocal Tract in Vowel Synthesis: A Comparison between 1D and 3D Acoustic Analysis
Negar M. Harandi, Daniel Aalto, Antti Hannukainen +2
A state-of-the-art 1D acoustic synthesizer has been previously developed, and coupled to speaker-specific biomechanical models of oropharynx in ArtiSynth. As expected, the formant…
Hierarchical Representation of Prosody for Statistical Speech Synthesis
Antti Suni, Daniel Aalto, Martti Vainio
Prominences and boundaries are the essential constituents of prosodic structure in speech. They provide for means to chunk the speech stream into linguistically relevant units by p…
Modal locking between vocal fold and vocal tract oscillations: Simulations in time domain
Atte Aalto, Tiina Murtola, Jarmo Malinen +2
During voiced speech, the human vocal folds interact with the vocal tract acoustics. The resulting glottal source-resonator coupling has been observed using mathematical and physic…
Neuronal calculus for the auditory pathway
Daniel Aalto, Martin Reimann, Eero Saksman
The first steps in the neural processing of sound are located in the auditory nerve and in the cochlear nuclei. To model the signal processing efficiently, we propose a simple math…
Measurement of acoustic and anatomic changes in oral and maxillofacial surgery patients
Daniel Aalto, Olli Aaltonen, Risto-Pekka Happonen +10
We describe an arrangement for simultaneous recording of speech and geometry of vocal tract in patients undergoing surgery involving this area. Experimental design is considered fr…
Modal locking between vocal fold and vocal tract oscillations: Experiments and statistical analysis
Daniel Aalto, Jarmo Malinen, Martti Vainio
The human vocal folds are known to interact with the vocal tract acoustics during voiced speech production; namely a nonlinear source-filter coupling has been observed both by usin…
How far are vowel formants from computed vocal tract resonances?
Daniel Aalto, Antti Huhtala, Atle Kivelä +4
We compare numerically computed resonances of the human vocal tract with formants that have been extracted from speech during vowel pronunciation. The geometry of the vocal tract h…
John-Nirenberg lemmas for a doubling measure
Daniel Aalto, Lauri Berkovits, Outi Elina Maasalo +1
We study, in the context of doubling metric measure spaces, a class of BMO type functions defined by John and Nirenberg. In particular, we present a new version of the Calderon-Zyg…
Weak and BMO in metric spaces
Daniel Aalto
Bennett, DeVore and Sharpley introduced the space weak in 1981 and studied its relationship with functions of bounded mean oscillation. Here we characterize weak $L^{\…
