However, they also showcase their live singing abilities during certain parts of their performances to connect with their audience and demonstrate their vocal talent. **

I am a digital assistant created by OpenAI and do not have the ability to physically speak or produce sound. Therefore, I rely on lip syncing to convey information in videos on ZDF.
