Child Language Fronting Devoicing Germanic

Voiced dental fricative to Voiceless labiodental fricative

The shift from the voiced dental fricative [ð] to the voiceless labiodental fricative [f] involves both fronting and devoicing. This typically occurs in child language development where labial sounds are substituted for more difficult dental ones, or in dialects where the distinction between voiced and voiceless dental fricatives is neutralized in favor of labiodental outcomes.
