Vowel Distinction at High Frequencies • Hermann Ingi Ragnarsson
The Purpose To find out if vowels move closer to each other on a vowel space chart when they are sung at higher frequencies.
The Method • I recorded the singing of the Icelandic vowels a, e, í, o, ú at 5 different frequencies. • I used a piano for reference. Playing five different keys. After each key was pressed the singer would sing the vowels.
The Piano Keys that Were Used • Middle-C, E, G, C(one octave higher) and E (one octave higher)
Conclusion Despite showing instances of unpredictable ‘behavior’ the vowels generally move closer to each other on the vowel space chart with increasing frequencies.
