How often does she have SALT? I would be tempted to say let's give it a complete break for a month or so, and then go back in with gusto and enthusiasm. If she's been learning one sound for over a year, can you suggest to the SALT that you could try focusing on a different sound instead?
Do you 'correct' her pronunciation? We were advised just to 'echo back' the sentence with standard pronunciation, but in a non judgemental way.
In English there are 'voiced' sounds (where the vocal chords are vibrating) and 'unvoiced' sounds (where they are not). Many of the consonants come in pairs, which are articulated identically (or very similarly), but just with the vocal chords on or off.
Your dd can clearly make voiced and unvoiced sounds, and can clearly do the articulation; as from your list she can often make one of the sounds of the pair.
unvoiced-voiced
p-b f-v c/k-g t-d s-z
etc.
I don't know the specifics of your situation, and ds1 never got to the stage of having a battery of assessments with ed psychs and so on. Other than the articulation problems, he didn't have any other developmental delays. But certainly at this age he had articulation problems which were more pronounced than your dd's.
(At this age he had never made any of the following sounds - c/g, s/z, f/v, sh, c/g, th, l, j, r ...etc! Maybe it would be quicker to list the sounds he could make!)
The other day I watched a video of ds1 when he was very small. The me now couldn't even begin to comprehend what he was saying, but the me then could clearly understand most of it! Even though it just appeared to be gibberish.
Anyway to give you some hope. He is now in yr8, and people often comment on how unusually articulate he is, he has a real talent for English and for MFL. He's recently won a national story writing competition, and next week will be picking up a whole fistful of academic prizes at his school's annual awards evening.
