They are doing the right thing by checking her hearing. Just because she jumps to a noise doesn't mean that she hears in the right way for learning to talk. They should also do a tympanogram to make sure that there isn't fluid behind her ear drum. Make sure you ask for that.
I am a big proponent for speech therapy because of my own son's experience. So know that when I tell you that I think that you should still give it some time. 14 months is very young still and well within the window of normality. You can help by not jumping to her every grunt, but saying "Do you want water? Wah-wah. Point to your mouth and wave your finger out with each syllable. Wah-wah." Little things like that. The first time you get something that even sounds like a word, go with it and try to develop it. And as she gets a little bigger, if she gets frustrated, try to teach her to say "Help me" by teaching her 'ep me. (Leave out the H and the L." )
There is a wide spectrum of "normal" between 12 months and 24 months. However, what is expected after 24 months is very different and you need to be aware of it. If I were you, I'd have her evaluated at 18 months if she doesn't get a lot of words by then. If she seems to be doing okay with it, then schedule an eval for right after she turns two. Do not wait until she is three.
Another thing you can do at home is work on her oral musculature. Find some of those sippy cups that have a straw that can't be squashed. You need one that is actually SHORT so that she can't grip it with her teeth. What you want is for her to have to use her lips to suck the liquid from it. I found several with straws that were too long and my husband cut them to a short length (made sure it wouldn't hurt her lips by sanding it) and that worked well. My son was also quite the drooler, and strengthening these muscles fixed that as well as helping his speech. We made milk shakes for him so that he had to WORK to suck on the straw, too.
There are little whistles that also have windmills on them that they blow on. This helps strengthen the musculature too, and it's fun. But you have to sit there with her and let her do it and then take it away (she's too little for you to let her just have it - choking hazard if she bit pieces off...)
These are actually things that speech therapists use, in case you're wondering. You can do this now in order to prepare her muscles.
Also, read a lot to her. Talk to her a lot. The more she hears, the more her mind makes the words and prepares her to be ready to talk.
Good luck.
