Using the…

Many of those can be objectively measured, such as acoustic-prosodic and structural-linguistic modifications. Perceived vocal affect, however, is a socio-emotional IDS characteristic and is subjectively assessed. Vocal affect goes beyond acoustic-prosodic…

This is the first large-scale study of resources as a form of "language management" -- that is, a way of influencing children's language practices. We introduce the distinction between child-directed resources (i.e. those providing parents with opportunities to engage with their children in the languages they are transmitting) and…
