1. An apparatus, comprising: a memory configured to store instructions; and a processor configured to execute the instructions to: receive multimedia content, wherein the multimedia content include video, audio, and captions, wherein the captions identify a textual representation of the audio, and wherein the multimedia content relates to dialog by a first speaker and a second speaker; perform image processing on the video to identify an age group of the first speaker and a gender of the first speaker, wherein the second speaker is not associated with at least one of the age group or the gender; determine, based on the image processing, a first portion of the video presenting a first portion of the dialog by the first speaker and a second portion of the video presenting a second portion of the dialog by the second speaker, wherein a first portion of the captions is associated with the first portion of the dialog and a second portion of the captions is associated with the second portion of the dialog; identify a first portion of the audio associated with the first portion of the video, and a second portion of the audio associated with the second portion of the video; filter the multimedia content to extract the first portion of the audio and the first portion of the captions and to remove the second portion of the audio and the second portion of the captions; and train an adaptive speech recognition system (ASR) with respect to the age group of the first speaker and the gender of the first speaker, wherein the processor, when training the ASR with respect to the age group of the first speaker and the gender of the first speaker, is further configured to: use the untrained ASR to perform a speech-to-text conversion of the first portion of the audio; calculate an error value based on comparing the first portion of the captions and results from the speech-to-text conversion using the untrained ASR; and use the first portion of the audio and the first portion of the captions to train the ASR when the error value is between a first threshold and a second threshold that is greater than the first threshold, wherein the first portion of the audio and the first portion of the captions are not used to train the ASR with respect to the age group and the gender of the first speaker when the error value is below the first threshold or greater than the second threshold.

The method of claim 1 , wherein the dialog by the first speaker and the second speaker relates to an environment associated with an attribute, and wherein training the ASR further includes: filtering the multimedia content to remove at least one of a part of the audio or a part of the captions associated with another environment, wherein the other environment is not associated with the attribute of the environment; and training the ASR further with respect to the attribute of the environment using the filtered multimedia content that excludes the at least one of the part of the audio or the part of the captions associated with the other environment.
