Abstract
The purposes of this study were to derive nasalance norms for monolingual Greek speakers, to examine
nasalance scores as a function of gender and to draw cross-linguistic comparisons based on normative
data.
Participants read aloud a corpus of linguistic material, consisting of (1) a nasal text, an oral text and a
balanced text; (2) a set of nasal sentences and four sets of oral sentences and (3) repetitions of each of 12
syllable types (8 oral and 4 nasal). The last two sets of material corpus were based on an adaptation of the
Simplified Nasometric Assessment Procedures Test (SNAP test) test (MacKay and Kummer, 1994) in
Greek, called the G-SNAP test. Eighty monolingual healthy young adult speakers of Greek, 40 males
(mean age ¼ 21 years) and 40 females (mean age ¼ 20.5 years), with normal hearing and speech
characteristics and unremarkable history were included in the study.
The Nasometer (model 6200-3) was used to derive nasalance scores. Mean normative nasalance for
spoken Greek was 25.50%, based on the G-oronasal text (with 8.6% nasals). Nasalance scores did not
differ significantly with respect to gender. Finally, spoken Greek consistently yielded lower nasalance
scores than other languages examined in past work.
The aforementioned normative data on nasalance of young adult speakers of Greek are valid across
gender and have direct clinical utility as they provide valuable reference information for the diagnosis
and management of Greek adults with resonance disorders caused by velar dysfunction.

Introduction
Nasometry, the sampling and measurement of nasal acoustic energy by a microcomputer-
based apparatus, the Nasometer, is a valuable instrumental method for the assessment of
nasality in speech (Fletcher and Bishop, 1973; Kay Elemetrics Corporation, 1994). The
Nasometer provides a nasalance score that corresponds to the ratio of nasal acoustic energy to
the sum of oral and nasal acoustic energy expressed as a percentage. The sampling of oral and
nasal acoustic energy is made from the mouth and nostrils, respectively, via two microphones,
mounted on opposite sides of a sound-separating plate placed at the upper lip.
