Overall, the laryngeal videoendoscopic and videostroboscopic recordings should have Speech intelligibility is an important variable in the oral communication, and it is indispensable to characterize all levels involved in this process, which are responsible for the correct and intelligible production of sounds. Miniature head-mounted microphone for voice perturbation analysis. Valid ratings of vocal fold vibration experts provided detailed written feedback on the second draft of the recommendations. Owing to the highly specialized nature of this technique it is typically carried out by suitably qualified radiographers. A clinical method for estimating laryngeal airway resistance during vowel production. An experimental application of the Delphi method to the use of experts. In an earlier study(23), by examining a general corpus of 150,875 words, it was found that 24.9% were oxytone, 62.5% were paroxytone and 12.2% proparoxytone, corroborating with the assertion that paroxytone words are the most frequent accentuation pattern in Portuguese. It is readily acknowledged, however, that this is not a perfect process. The data obtained through the assessments provided adequate analysis. Please enable it to take advantage of the complete set of features!

In order to participate in the final stage of the protocol elaboration, three PhD speech therapists with experience in the elaboration of evaluation instruments and speech therapy using figures were chosen.
