Summary
Formant frequencies in Middle Eastern singers differ between speaking and singing for vowels /a/, /i/, and /u/. The study found no evidence of the singer's formant in this group.
Area of Science:
- Speech and Hearing Science
- Acoustic Phonetics
- Vocal Pedagogy
Background:
- Formant frequencies are crucial for vowel acoustics.
- The singer's formant is a phenomenon observed in operatic singers, characterized by a spectral peak.
- Understanding formant variations in different singing styles and ethnicities is important for vocal science.
Purpose of the Study:
- To describe formant frequencies (F1, F2, F3, F4) in Middle Eastern singers during speech and singing.
- To investigate the presence or absence of the singer's formant in this population.
Main Methods:
- A cohort of 13 Middle Eastern singers (5 male, 8 female) participated.
- Descriptive analysis of formant frequencies for vowels /a/, /i/, and /u/ in both speaking and singing conditions.
- Wilcoxon signed-rank test used to compare formant means between speaking and singing.
Main Results:
- Significant differences in formant frequencies were observed for vowels /a/, /i/, and /u/ between singing and speaking.
- Specifically, F1 singing was lower than F1 speaking for /a/; F2 singing was higher than F2 speaking for /u/; F2 and F3 singing were lower than F2 and F3 speaking for /i/.
- No spectral clustering indicative of the singer's formant was detected in the sung vowels.
Conclusions:
- Vowel formant frequencies exhibit distinct patterns in Middle Eastern singing compared to speaking.
- The characteristic singer's formant, as typically defined, is absent in this group of Middle Eastern singers.

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...
01:29IR Frequency Region: Alkene and Carbonyl Stretching
Double bonds in alkenes and carbonyl compounds exhibit stretching frequencies in the diagnostic region of the IR spectrum. In addition, alkenes exhibit vinylic C–H stretching and C–H out-of-plane bending absorptions that are useful for identifying substitution patterns.
Stretching frequencies are affected by several factors, such as resonance, inductive effects, ring strain, dipole moment, and hydrogen bonding. Consequently, the stretching frequency of the carbonyl double bond varies in...

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...
01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:22IR Frequency Region: Alkyne and Nitrile Stretching
Both alkyne (C≡C) and nitrile (C≡N) functional groups contain triple bonds and show stretching absorptions around the wavenumber range of 2100 to 2300 cm−1 in the diagnostic region of the IR spectra.
Comparing the stretching vibrational frequency of C≡C triple bonds with that of double and single bonds, it is evident that C≡C triple bonds exhibit a higher stretching frequency than C=C double and C–C single bonds. Similarly, the C≡N triple bond exhibits higher stretching absorption than the C=N...
