PurposeThis study aimed to investigate the relationship and reliability of cepstral peak prominence (CPP) measures from two acoustic software applications, Analysis of Dysphonia in Speech and Voice (ADSV) and Praat.MethodologyFlemish and English recordings of sustained vowels and connected speech samples were analyzed using ADSV and Praat. Correlational analyses and measures of the standard error of the estimate were applied to the vowel and connected speech data obtained from the two programs.ResultsAnalyses revealed very strong relationships (eg, r > 0.88) between CPP measures derived from ADSV and those derived from Praat, regardless of context (vowel or connected speech) or language spoken. Average residual errors ranged from 0.55 to 1.1 dB for the prediction of Praat CPP data from actual observed ADSV CPP data, and average residual errors ranged from 0.57 to 1.58 dB for the prediction of ADSV CPP data from actual observed Praat CPP data.ConclusionsMeasurements of CPP derived from ADSV and Praat manifested strong parallel-forms reliability. Although CPP data values obtained via these programs will be different owing to algorithmic processing differences, this study found that estimated CPP values derived using regression equations could be transformed between programs with relatively small predictive error, regardless of language. The strong measurement relationships indicate that CPP values from either program have a high degree of shared variance and may be expected to differentiate across a wide range of voice signal periodicity in a relatively similar fashion. This finding supports the use of either program in clinical use and voice science research.

Abstract
BACKGROUND: Dehiscence syndromes of the semicircular canals are a relatively new group of neurotological disorders. They have a variety of symptoms with hearing/balance involvement. Younger patients have clinically relevant symptoms in only about one third of cases. In addition to etiology and pathogenesis, the present paper describes diagnostic and therapeutic possibilities using a patient series of the authors.
MATERIALS AND METHODS: This nonrandomized prospective study included 52 patients with uni-/bilateral dehiscence syndromes of the superior and/or posterior canal (SCDS/PCDS), diagnosed with high-resolution computed tomography (HR-CT) of the petrous bone. Of 41 patients undergoing surgical therapy for severe symptoms-predominantly vertigo attacks (Meniere-like) and/or falls (Tumarkin crises)-31 received single-sided hearing implants.
RESULTS: Of the 41 patients with transmastoid superior and/or posterior canal occlusion, 30 showed a significant improvement of balance in the Dizziness Handicap Inventory (DHI); the dizzy spells ceased. A positive outcome was correlated with the severity of the preoperative disorder; a poor outcome (nonsignificant increase in DHI, recurrent vertigo of various qualities/frequencies) with the comorbidities vestibular migraine, Menière's disease of the contralateral ear, and a dehiscence size exceeding 4 mm.
CONCLUSION: The more severe the vestibular symptoms, the better the outcome of surgical therapy. Auditory symptoms (nonspecific aural fullness, hyperacusis) do not generally respond well to surgical therapy. Cochlear implants have an additional beneficial effect; comorbidities should be considered as (relative) contraindications.
