Summary
This study analyzed acoustic characteristics of the Arabic voice, finding significant differences in formant frequencies between adult males, females, and children. These findings establish new formant norms for Jordanian Arabic speakers.
Area of Science:
- Linguistics
- Acoustics
- Speech Science
Background:
- Understanding the acoustic properties of the Arabic voice is crucial for speech-language pathology.
- Existing data on Arabic voice acoustics, particularly for Jordanian speakers, is limited.
Purpose of the Study:
- To investigate the acoustic characteristics of the normal Arabic voice across different age and gender groups.
- To establish normative data for formant frequencies of sustained Arabic vowels.
- To provide updated reference values for Jordanian Arabic speakers.
Main Methods:
- Acoustic analysis of sustained phonation of six Arabic vowels (/i:/, /e:/, /a:/, , /o:/, /u:/).
- Inclusion of 300 normal Arabic speakers: 100 adult males, 100 adult females, and 100 children.
- Utilized Time-Frequency Analysis Software (TF32) to analyze fundamental frequency (F0) and formant frequencies (F1, F2, F3).
Main Results:
- Significant differences in formant frequencies were observed between adult males and females/children.
- Significant differences in F1 were found between females and children, but not in F2 or F3.
- Comparisons with other ethnicities revealed distinct patterns in F1, F2, and F3 across adult Arab males, adult Arab females, and children.
Conclusions:
- The study provides normative acoustic data for the Jordanian Arabic voice, differentiating by sex and age.
- Speech-language pathologists in Jordan should utilize these new formant norms for accurate evaluation and treatment.
- This research contributes to a better understanding of Arabic phonetics and its clinical applications.

01:19Expected Frequencies in Goodness-of-Fit Tests
A goodness-of-fit test is conducted to determine whether the observed frequency values are statistically similar to the frequencies expected for the dataset. Suppose the expected frequencies for a dataset are equal such as when predicting the frequency of any number appearing when casting a die. In that case, the expected frequency is the ratio of the total number of observations (n) to the number of categories (k).
01:08Determination of Expected Frequency
Suppose one wants to test independence between the two variables of a contingency table. The values in the table constitute the observed frequencies of the dataset. But how does one determine the expected frequency of the dataset? One of the important assumptions is that the two variables are independent, which means the variables do not influence each other. For independent variables, the statistical probability of any event involving both variables is calculated by multiplying the individual...
00:55Relative Frequency Distribution
A relative frequency distribution is the proportion or fraction of times a value occurs in a data set. To find the relative frequencies, one can divide each frequency by the total number of data points in the sample. It is very similar to a regular frequency distribution, except that instead of reporting how many data values fall in a class, a relative frequency distribution reports the fraction of data values that fall in a class. These fractions or proportions are called relative frequencies...
01:03IR Frequency Region: Fingerprint Region
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the C=O, C=N, and C=C occur between 1600–1850 cm−1.

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single stretching vibration...
01:24IR Frequency Region: X–H Stretching
In IR spectroscopy, signals produced by the X−H bonds (such as C−H, O−H, or N−H) can be observed in the frequency range of 2700–4000 cm–1. The C−H stretching vibration forms sharp bands in the region 2850–3000 cm–1. The presence of the O−H stretching vibration leads to the forming of an absorption band in the frequency range 3650–3200 cm−1. At the same time, N−H stretching can be confirmed by absorption bands in the 3500–3100 cm−1 range. Even though both O−H and N−H bonds vibrate at a similar...
