1. A method for modifying recorded audio of a video title, the method comprising: identifying, by at least one processor of a device, a video title available for presentation; identifying, by the at least one processor, a portion of audio data, of the video title, representing dialogue spoken by an actor of the video title; identifying, by the at least one processor, the actor who spoke the dialogue; dividing, by the at least one processor, the portion of the audio data into a first portion representing the dialogue and a second portion representing background noise during the dialogue; identifying, by the at least one processor, a first lexical word of the dialogue to be replaced in the video title; identifying, by the at least one processor, a first time at which the actor begins to speak the first lexical word and a second time at which the actor finishes speaking the first lexical word; selecting, by the at least one processor, based on a time duration between the first time and the second time, a second lexical word different than the first lexical word to replace the first lexical word in the portion of the audio data; identifying, by the at least one processor, a voice profile of the actor, wherein the voice profile represents audio samples of a voice of the actor from at least one of the video title or an additional video title; generating, by the at least one processor, based on the voice profile, first speech signals simulating the actor speaking the second lexical word; removing, by the at least one processor, second speech signals representing the actor speaking the first lexical word from the dialogue; adding, by the at least one processor, the first speech signals into the dialogue using at least a portion of the time duration; combining, by the at least one processor, the background noise with the dialogue into which the first speech signals were combined; and generating, by the at least one processor, a modified version of the video title comprising the background noise with the dialogue into which the first speech signals were added.
