- The fundamental frequency of a speech signal, often denoted by F0 or F 0, refers to the approximate frequency of the (quasi-)periodic structure of voiced speech signals. The oscillation originates from the vocal folds, which oscillate in the airflow when appropriately tensed.

What is fundamental frequency?
Fundamental frequency. The voiced speech of a typical adult male will have a fundamental frequency from 90 to 155 Hz, and that of a typical adult female from 165 to 255 Hz. [3] Thus, the fundamental frequency of most speech falls below the bottom of the voice frequency band as defined.
The Fundamental Frequency, or Fo, is more commonly referred to as pitch. The difference between the fundamental frequency and a pitch is that a pitch created by a singer, or most instruments, contains multiple frequencies including the fundamental frequency and overtones.

The fundamental frequency or pitch of the voice is sometimes referred to as F0, but it is not a formant. Most often the two first formants, F1 and F2, are sufficient to identify the vowel.
Keep on reading to find out more about fundamental frequency in linguistics, including a definition, some examples, and some facts about the frequencies of our voices! We will also explore the relationship between fundamental frequency, pitch, and harmonics.
The fundamental frequency for speech ( f o) is typically 100 to 400 Hz. For singing, the range may be from about 60 Hz to over 1500 Hz, depending on the type of voice.
Fundamental frequency is the lowest frequency of a periodic waveform, representing the main pitch of a sound. It is crucial in defining the characteristics of speech sounds, as it helps determine the pitch and intonation of a speaker's voice.
