Formantberekeningen

Formantberekeningen refer to the process of determining the formants of a sound, particularly speech. Formants are the resonant frequencies of the vocal tract, which are amplified during speech production. They are crucial in distinguishing different vowel sounds, as the pattern of formants is unique for each vowel. Formantberekeningen typically involve analyzing the acoustic spectrum of a sound. This is often done using a Fast Fourier Transform (FFT), which breaks down the sound into its constituent frequencies. The peaks in the resulting spectrum correspond to the formants. The first two formants, F1 and F2, are generally the most important for vowel identification. F1 is inversely related to vowel height, meaning lower vowels have lower F1 values and higher vowels have higher F1 values. F2 is related to vowel frontness, with front vowels having higher F2 values and back vowels having lower F2 values. Formantberekeningen are fundamental in fields such as phonetics, speech synthesis, speech recognition, and voice analysis. They allow researchers and developers to understand and replicate the acoustic properties of speech.
