Overlapping / crossing voices Dataset (audio+transcripts)

Dear Friends, I am looking for the **overlapping /crossing voices training dataset (audio with transcripts)**. I want to finetune the deepspeech. If there is any advice or helping hint how and where I can find that kind of dataset. I am looking in English, German and other common languages available data.
So far, I have seen the common voice dataset very good for single voices. But your kind help is highly appreciated if someone can guide me.
