Speech is the faculty of producing articulated sounds, which, when blended together, form language.
The sounds f and v are both classified as fricatives, meaning they are produced by narrowing the vocal tract to create audible friction as air passes through, rather than making a complete closure. Both sounds share the same place of articulation, as they are labiodental consonants produced by positioning the mouth in the same way.1
The primary difference between them lies in voice:
- f: This is a voiceless sound, meaning it is produced without the vibration of the vocal cords.2
- v: This is a voiced sound, meaning it is produced while the vocal cords vibrate.2
Because v involves vocal cord vibration, it possesses a periodic waveform, whereas f does not.23
