2. The apparatus of claim 1 , wherein the processor, when filtering the multimedia content to extract the first portion of the audio and the first portion of the captions, is further configured to: identify a start time and an end time for the first portion of the audio; perform a confidence determination between the first portion of the audio and the first portion of the captions; and adjust at least one of the start time or the end time based at least in part on the confidence determination.
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.
