Yes it's good to have everyone's opinion here but with regards to speech, each child is so different that some comments such as 'speak to her more' or 'watch less TV' are probably not very helpful!
'small talk' is a good book but mostly aimed at young toddlers. We have been through 3 years of speech therapy, many books, trainings etc with DS2 who has a speech disorder, so I won't claim I'm an expert but I we have been through a lot.
I am sure you do lots of what I will say but here are a few games:
Sit your dd on your lap and at eye level, just pull faces and make silly sounds and try to get her to copy you. Any sound at all should be praised, even raspberries or iii sounds. Try sounds like 'da da da' or just 'a a a'. get her to try to blow kisses, stick get tongue out, etc. this is very good to get her more aware of the muscles in her face and have more control of sounds/movement.
Keep sentences clear, short, and repeat key words. ie. 'would you like some milk? Nice MILK. Cold MILK. MILK?' try to apply this to many communications you will have throughout the day.
Sing lots of nursery rhyme. Try to show her how to hum them. Or when she is ready, drop a word in the rhyme and see if she might try to fill in the blank. If she doesn't it's fine, just say the word. Don't ask too many questions just comment on her play. Make lots of noises, car noises, animal sounds, use simple words like 'up-down' and '1-2-3' as many times a day as you can.
If she gets frustrated because she can't say what she wants, try to get her to show you, to point, to share with you in any way she can. use cards with images, or use Makaton signing.
My son's first words were words that were accompanied by movement - I don't know if that'ssignificant in any way, but words such as 'bye', 'hello' can be accompanied by a hand movement and that seem to help him to say the word.
