Hi and welcome. Guinea Pigs are great and rewarding pets. The forum hasn’t been very active lately, so I recommended signing up for a more active forum as well. Like http://www.guinealynx.info/forums/ They are super active and know what they are talking about, and will surely answer the many questions you’ll have =)
We’re really nice here, but there’s not many active members at the moment.
It’s great that you are talking to the guinea pig, that’s a great step for bonding, gets them used to your voice etc. Some pigs like getting picked up more than others. But at the beginning pigs are always slightly fearful. I personally recommended holding your new piggie daily, to get used to you, but sometimes it might just be for little bit, it will take time, sitting by the cage, just chatting with them and getting them used to you being there, and showing that you are not a threat is wonderful.
I have linked some great videos about how to bond with your piggie etc. here.

Another thing to consider if they are squeaking and really not liking being touched is they may have a skin problem or an illness. I would recommenced taking them to the vet to get the piggie all checked out just in case. Most guinea pigs that were classroom pets are often from pet stores, and pet store pigs often come with illnesses. With proper vet treatment, it’s can be a simple fix, just get them checked out. Guinea Pigs are considered exotic- so they will need an exotic vet that has experience with guinea pigs - here’s a list of some guinea pig vets. http://www.guinealynx.info/vetlist.html
