Ayla-What+am+I???

What am I? I come in various sizes. I am there to help when you are in need, though I cannot move. I can take you to places and I can also play with you. I have a voice that can be turned down or up. I have a mouse, but not a cat. I can take pictures and keep them stored. I have a wide vocabulary and correct you when you make a mistake. Consider me an automatic dictionary. I can do all sorts of things but I’m not really the sporty type. What am I?

What am I? I have different colours. Whenever you come near me, I go further away. People try, but cannot touch me. I am very flexible. I only appear when people are inside. Some people believe I’m a portal to a different place. What am I?

What am I? I don’t have legs nor arms, but I do have a face. Sharp concrete or other hard surfaces hurt me whenever I am being used. I can be any colour or any size. I am a circular object. What am I?
