Create a digital artwork of an AI telephone assistant represented by a futuristic silhouette, blending elements of technology and humanity. The figure should be abstract, wearing a headset with a small earpiece or microphone, emphasizing its role as a communication assistant. Position the assistant on the right side of the image, facing towards the left. Include flowing lines or shapes that suggest sound waves, digital connections, or data streams emanating from a smartphone or floating interface. Focus on a color palette dominated by various shades of blue, with subtle hints of pink or rose, all set against a dark or black background. The image should be 1080px by 400px, creating a modern, sleek, and technologically advanced header
