Preliminary glottal source modeling for pathologic voices
A first attempt at implementing a flexible model for the glottal source waveform of pathologic voices is described. The LF (Liljencrants & Fant) model is the source model used. We also add various noise types, shimmer and jitter to the excitation source in order to replicate more closely the pathologic glottal waveform. Various vocal characteristics are then modeled in order to evaluate the per...
متن کاملInfluence of Reading Errors on the Text-Based Automatic Evaluation of Pathologic Voices
In speech therapy and rehabilitation, a patient’s voice has to be evaluated by the therapist. Established methods for objective, automatic evaluation analyze only recordings of sustained vowels. However, an isolated vowel does not reflect a real communication situation. In this paper, a speech recognition system and a prosody module are used to analyze a text that was read out by the patients. ...
متن کاملEvaluation and Assessment of Speech Intelligibility on Pathologic Voices Based upon Acoustic Speaker Models
We describe a GMM-UBM-based evaluation system for pathologic voices that uses standard cepstral features. Per speaker one GMM is created and its components are used to create a so-called GMM supervector. The supervector of each speaker is labeled with the intelligibility values obtained by human evaluation and is used to train an SVR. We studied different GMM supervectors containing different G...
متن کاملAcoustic "breathiness measures" in the description of pathologic voices
One important perceptual attribute of voice quality is breathiness. Since breathiness is generally regarded to be caused by glottal air leakage, acoustic measures related to breathiness may be used to distinguish between different physiological phonation conditions for pathological voices. Seven “breathiness features” described in the literature plus one self-developed measure (the glottal to n...
