“…As for English, standard passages including Zoo Passage, Nasal Sentences, and Rainbow Passage have been used for establishing normative nasalance data for oral, nasal, and oronasal stimuli, respectively (Fletcher, 1976; Dalston et al, 1991a, 1991b). Similar speech materials consisting of oral, nasal, and oronasal stimuli for other languages including Swedish (Brunnegård & van Doorn, 2009), Flemish (D’haeseleer et al, 2015), Malay (Ibrahim et al, 2012), Vietnamese (Nguyen et al, 2019), and Korean (Park et al, 2014) have been developed as well. The ranges of normative nasalance scores for oral, nasal, and oronasal stimuli in different languages have been reported as 6.8 to 34.9, 41.3 to 78.0, and 16.9 to 39.5, respectively (Haapanen, 1991; Kavanagh et al, 1994; Prathanee et al, 2003; Van Lierde et al, 2003; Sweeney et al, 2004; Hirschberg et al, 2006; Falé & Hub Faria, 2008; Mishima et al, 2008; Brunnegård & van Doorn, 2009; Van der Heijden et al, 2011; Okalidou et al, 2011; Ibrahim et al, 2012; Luyten et al, 2012; Kuppusamy et al, 2013; Lee & Browne, 2013; Park et al, 2014; D’haeseleer et al, 2015; El-Kassabi et al, 2015; Hamdan et al, 2015; Maturo et al, 2017; Nguyen et al, 2019).…”

Objective: The Kay Pentax nasometer uses a separator plate that touches the philtrum of a patient to separate the nasal and oral sound energies for nasalance measurement. However, the separator plate can restrict the natural movement of the patient’s upper lip and generate unpleasant pressure on the patient’s philtrum. The present study was intended to measure nasalance scores without touching the philtrum for better comfort during speech assessment and therapy. Methods: Nasalance scores of 10 males and 10 females having no speech disorders were measured under 4 levels (0, 5, 10, and 15 mm) of the gap between the plate and the philtrum (denoted as plate-to-philtrum gap) using Nasometer II 6450 for nasal (Nasal Sentences) and oral (Zoo Passage) stimuli. Regression formulas were established to examine the relationships between nasalance score and plate-to-philtrum gap for the stimuli. To provide nasalance scores equivalent to those measured for the contact condition, compensation factors for the 5 mm plate-to-philtrum gap measurement condition were identified for the stimuli. Results: The nasalance scores were significantly different between the 4 different plate-to-philtrum gaps for the stimuli. Compensation factors for the Nasal Sentences and the Zoo Passage were identified as 1.17 and 0.71, respectively. Conclusions: The 5 mm plate-to-philtrum gap condition after multiplying the compensation factors can provide equivalent nasalance scores to the conventional contact measurement condition which may provide better comfort in speech assessment and therapy.

“…Nasometry, a method of measuring the acoustic correlates of resonance, gives the examiner a nasalance score that is the ratio of nasal acoustic energy relative to the total acoustic energy of the nasal and oral output [1]. Research conducted to establish nasalance norms for Standard American English (SAE) speakers [2] led to the establishment of nasalance norms in other languages, for example, Flemish [3], Malay [4], Turkish [5], Estonian [6], Japanese [7], Vietnamese [8], Greek [9], Korean [10], and Thai [11]. However, there are no established norms for Arabic-speaking Jordanians.…”

“…No differences were found in Japanese [7], Korean [10], and Turkish [5] speakers. By contrast, differences were found between female and male speakers of Vietnamese [8], Flemish [3], Irish English [21], Greek [9], Ugandan English [20], and Estonian [6].…”

Objective: This investigation sought to establish nasalance scores for Jordanian Arabic (JA) speakers, to develop nasalance speech stimuli for JA speakers, and to compare JA adult nasalance scores with those of Standard American English (SAE) speakers. Subjects and Methods: Participants included normal native JA speakers (n = 100; males/females and adults/children) and adult SAE speakers (n = 49). Four speech tasks for JA speakers were developed, which included repetition of vowels, syllables, words, and sentences. Parallel speech tasks were also developed for SAE speakers. A nasometer (Nasometer II 6400; PENTAX Medical, Montvale, NJ, USA) was used to establish nasalance scores for all speakers across all speech tasks. Results: Nasalance values were established for adult and child JA speakers. The nasalance values were higher for Jordanian adults than for Jordanian children. No differences in nasalance were found between male and female Arabic speakers for nonnasal elements. JA speakers were significantly more nasal than SAE speakers on selected speech tasks. Conclusions: Nasalance values for JA speakers were established for both adults and children, and Arabic speech materials were developed. The results of this investigation add to the growing body of research documenting differences in nasalance scores for normal speakers across different languages.

Background: The Kay Pentax Nasometer uses a separator plate that touches the philtrum of a patient to separate the nasal and oral sound energies for nasalance measurement. However, the separator plate could restrict the natural movement of the patient’s upper lip and generate an unpleasant pressure to the patient’s philtrum. The present study was intended to measure nasalance scores without touching the philtrum for better comfort during speech assessment and therapy.Methods: Nasalance scores of 10 males and 10 females having no speech disorders were measured under four levels (0, 5, 10, and 15 mm) of the gap between the plate and the philtrum (denoted as plate-to-philtrum gap) using Nasometer II 6450 for nasal (Nasal Sentences) and oral (Zoo Passage) stimuli. Regression formulas were established to examine the relationships between nasalance score and plate-to-philtrum gap for the Nasal Sentences and the Zoo Passge, respectively. To provide equivalent nasalance scores measured under the 5-mm plate-to-philtrum gap to those measured under the conventional contact measurement condition (i.e., the 0-mm plate-to-philtrum gap in the present study), compensation factors were identified as the ratio of the mean nasalance measured under the 0-mm gap to that measured under the 5-mm gap for the Nasal Sentences and the Zoo Passge, respectively. The validation of the identified compensation factors was examined.Results: The nasalance scores were significantly different between the four different plate-to-philtrum gaps for the stimuli. Nonlinear and linear regression formulas were established for the relationships between nasalance score and plate-to-philtrum gap for the Nasal Sentences and the Zoo Passage, respectively. Compensation factors for the Nasal Sentences and the Zoo Passage were identified as 1.17 and 0.71, respectively. Validation results showed that the adjusted nasalance scores after mutiplying the identified compensation factors were similar to those measured under the conventional contact measurement condition for both the oral and nasal stimuli.Conclusions: The 5-mm plate-to-philtrum gap condition after multiplying the compensation factors can provide equivalent nasalance scores to the conventional contact measurement condition and better comfort in speech assessment and therapy.
