Hi there,
I have potty trained a few of our children right about the age where their vocabulary is broad enough to us words to communicate and also to understand what it is I'm wanting them to do. It has usually fallen at 2yrs. of age. That's not to say, that some pretraining didn't go on before that. You can certainly try letting her sit on a smaller potty around the house to get use to the feel of it. (with or without clothes on) Then gradually move it closer to the bathroom. Try taking her into the bathroom with you to use the potty and she will begin to understand what goes on. As it gets closer to summer, I find it's easier to just let my almost 2 yr. old wear panties and a dress, or T-shirt, that way it's a little easier to take her frequently and she won't be annoyed by having to climb in and out of pants so much.
Overall, I'd say, whether she's talking or not, if she's showing signs of staying dry in her diaper at night, and for long periods during the day, try taking her as soon as she wakes up and then again after meals. See how she does by just sitting her there and not making a big fuss over it. Let her get down if she wants and go about your day. Try again in about an hour or so. If she becomes mad, or reluctant to go with you or says "no", then just be patient and give her a few more days, or another week. Certainly, if she is showing signs of being upset about your new activity for her, I would stop for a bit then reintroduce it slowly sometime later.
Good luck,
