Reading aloud appears to be an important lever for improving language acquisition and development in early childhood, and later in life it strengthens many sub-dimensions of language. However, the availability of numerous variations on reading training, shaped by different methodologies and different lengths of exposure make it difficult to determine the best approaches to follow. The aim of this review is to identify the available literature contributions that examine the association between mediated reading training, first language development and the acquisition of new vocabulary, including other components that could be improved by these interventions, such as cognitive function, emergent literacy and adult-child verbal interactions. The purpose is to compare research highlighting their fundamental characteristics, tools, duration and methodologies used in order to point out the effects that the practice of reading aloud produces on the acquisition and the enhancement of language, particularly in the age of language development. The analysis of the 51 articles included aims to identify the most effective reading strategies in terms of practices, timing and methods, able to produce the most significant gains in the language area.
