“…As for nasalance data, among the studies that include Pearson correlation (i.e., they included a large number of participants), we find only one [32] with an r value higher than ours (r = 0.88 versus r = 0.82). All other studies obtained poorer results: 0.74 [33], 0.59 [34], or 0.55 [35].…”

“…Despite such a limitation, it is relevant to compare their results with nasalance studies (as these also evaluate hypernasality based on running speech). By selecting only nasalance studies with a number of participants large enough to compute the Pearson correlation, we find that one study obtained a very high correlation of 0.88 [32], but in all other studies, the correlation is notably lower: 0.74 [33], 0.59 [34], and 0.55 [35]. Thus, it seems that the above-described DNN model might be a good alternative to the Nasometer.…”

Automatic evaluation of hypernasality has been traditionally computed using monophonic signals (i.e., combining nose and mouth signals). Here, this study aimed to examine if nose signals serve to increase the accuracy of hypernasality evaluation. Using a conventional microphone and a Nasometer, we recorded monophonic, mouth, and nose signals. Three main analyses were performed: (1) comparing the spectral distance between oral/nasalized vowels in monophonic, nose, and mouth signals; (2) assessing the accuracy of Deep Neural Network (DNN) models in classifying oral/nasal sounds and vowel/consonant sounds trained with nose, mouth, and monophonic signals; (3) analyzing the correlation between DNN-derived nasality scores and expert-rated hypernasality scores. The distance between oral and nasalized vowels was the highest in the nose signals. Moreover, DNN models trained on nose signals outperformed in nasal/oral classification (accuracy: 0.90), but were slightly less precise in vowel/consonant differentiation (accuracy: 0.86) compared to models trained on other signals. A strong Pearson’s correlation (0.83) was observed between nasality scores from DNNs trained with nose signals and human expert ratings, whereas those trained on mouth signals showed a weaker correlation (0.36). We conclude that mouth signals partially mask the nasality information carried by nose signals. Significance: the accuracy of hypernasality assessment tools may improve by analyzing nose signals.

“…For each child, the evaluating SLP performed auditory-perceptual assessment of resonance using a 5-point Likert scale first used by Karling and colleagues, 50 and subsequently utilized by others. 55,67 Similar 5-point scales have been widely used to perform auditory-perceptual ratings of resonance. 14,37,55,67,68 Clinicians rated resonance as either normal (0), mildly hypernasal (1), moderately hypernasal (2), severely hypernasal (3), or profoundly hypernasal (4).…”

[42][43][44] This variation in findings may be partially related to the stimuli used.…”

To investigate the relationship between auditory-perceptual ratings of resonance and nasometry scores in children with cleft palate. Factors which may impact this relationship were examined including articulation, intelligibility, dysphonia, sex, and cleft-related diagnosis. Retrospective, observational cohort study Outpatient pediatric cranio-facial anomalies clinic Four hundred patients <18 years of age identified with CP ± L, seen for auditory-perceptual and nasometry evaluations of hypernasality as well as assessments of articulation and voice. Relationship between auditory-perceptual ratings of resonance and nasometry scores Pearson's correlations indicated that auditory-perceptual resonance ratings and nasometry scores were significantly correlated across oral-sound stimuli on the picture-cued portion of the MacKay-Kummer SNAP-R Test (r values .69 to.72) and the zoo reading passage (r = .72). Linear regression indicated that intelligibility ( p ≤ .001) and dysphonia ( p = .009) significantly impacted the relationship between perceptual and objective assessments of resonance on the Zoo passage. Moderation analyses indicated that the relationship between auditory-perceptual and nasometry values weakened as severity of speech intelligibility increased ( P < .001) and when children presented with moderate dysphonia ( p ≤ .001). No significant impact of articulation testing or sex were observed. Speech intelligibility and dysphonia alter the relationship between auditory-perceptual and nasometry assessments of hypernasality in children with cleft palate. SLPs should be aware of potential sources of auditory-perceptual bias and shortcomings of the Nasometer when following patients with limited intelligibility or moderate dysphonia. Future study may identify the mechanisms by which intelligibility and dysphonia affect auditory-perceptual and nasometry evaluations.

Introduction: Assessment of resonance characteristics is essential in research and clinical practice in individuals with velopharyngeal impairment. The purpose of this study was to systematically review correlations between auditory-perceptual ratings and nasalance scores obtained by a nasometer in individuals with resonance disorders and to identify factors that affected the correlations between these two measures. Method: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic search was conducted for studies reporting a correlation between nasality ratings and nasalance scores using six electronic databases based on predefined inclusion and exclusion criteria. Results: A total of 27 studies were included in this systematic review. Characteristics of study components including participants, types of assessment and stimuli, correlation coefficients, and reliability values of each study were identified, and a narrative synthesis was conducted. The methodological quality of each study was also appraised. The correlation level between nasalance values and nasality ratings varied from nonsignificant to strong ( r = .92). The quality rating scores of the selected studies ranged from 44% to 94%, with an average score of 75%. Discussion: Factors that did or did not affect the varied correlation between nasality ratings and nasalance scores were discussed. Speech stimuli and the listeners' background were associated with correlations between the two measures. In addition, the sex of the speakers could be a factor affecting its correlation. However, the types of perceptual scales and listening conditions did not influence its correlations between the two measures. Supplemental Material: https://doi.org/10.23641/asha.19653207
