Objective evaluation of hoarse voice.

Improvement in hoarse voice denoising for real-time DSP implementation

Voice hoarseness is mainly related to airflow turbulence in the vocal tract. It can be due to vocal fold paralysis, polyps, cordectomisation or other dysfunction, which alter regular speech production, and is commonly treated as a noise component in the speech signal. A denoising approach is proposed, based on low-order singular value decomposition (SVD) of matrices whose entries come from samp...

Synthetic hoarse voices: a perceptual evaluation

Objective evaluation of TE substitute voice and speech

Three studies are presented which aim at rater-independent methods to evaluate voice quality, speech intelligibility and the benefit of rehabilitation of the patients: (1) real time endoscopy of the vibrating PE segment, (2) quantification of speech intelligibility by means of a computerized speech recognition system and (3) rating of the laryngectomees’ quality-of-life in relation to his subst...

Language-independent automatic evaluation of intelligibility of chronically hoarse persons.

OBJECTIVE Automatic intelligibility assessment using automatic speech recognition is usually language specific. In this study, a language-independent approach is proposed. It uses models that are trained with Flemish speech, and it is applied to assess chronically hoarse German speakers. The research questions are here: is it possible to construct suitable acoustic features that generalize to o...

Mediastinal traction injury to the recurrent laryngeal nerve: An unusual cause for a hoarse voice

BACKGROUND Chest wall trauma is a frequent cause for emergency department presentations, with traumatic pneumathoraces a relatively common occurance. Vocal cord paralysis however, is uncommon. CASE REPORT A 44 year old man presented with a traumatic pneumothorax following a fall. A weak and hoarse voice was noted and vocal cord palsy demonstrated on indirect laryngoscopy. CT chest was unremar...
