Abstract: Systems for facilitating acquisition of a language by a user receive initial user input representing a phrase in a first language. The phrase is translated to a second language then parsed to generate constituent data indicative of one or more groups of related words within the phrase. The constituents may constitute comprehensible linguistic inputs for communication to a user when the initial phrase is not a comprehensible input. Output data is generated to output the constituents to the user. Based on the relationships between the words, the characteristics of the second language, or user data indicative of the user's previous comprehension of constituents, the amplitude, frequency, output rate, or other audible characteristic of output may be modified to emphasize or deemphasize portions of the constituents.
