Filter Only Child's Speech Part

I would like to confirm if the recordings need to be preprocessed to filter out the adult speech parts and retain only the child’s part. For example, utterance U_7b2b7bc9ba8fbd0f has an adult talking in the beginning, but the transcript does not contain that part. Thanks.

Thanks for your comment @uamo! Confirming that yes, the recordings have been preprocessed to focus on the child’s speech. We attempted to exclude adult speech during segmentation and transcription. That said, this process isn’t perfect, and there may be a small number of cases where brief adult speech remains in the audio. In general, the transcripts should correspond only to the child’s utterances.
