CoLaJE is a French open access database (available in CHILDES) containing longitudinal recordings of in vivo child spoken language from seven children that have been regularly filmed one hour every month from their first year of life until 5. Each record has been transcribed in CHAT, for two children an additional transcription in orthographic norm and IPA is provided. Data is coded in two tier : “pho” reprents what the child says and“mod” represents what the child should have said according to the adult’s norm. This sampling scheme meets child language representativeness standards (Stahl & Tomasello, 2004).
