Here's the translation, it starts at 1hr57 within the flight. C for captain, PF, PNF.
C: Well, all you have to do is wake him up from er flight rest
PF: Ok, the little turbulence you've just seen, we should keep getting it cuz we're in the layer and unfortunately we can't climb for now, the temperature doesnt decrease like it should, so we get REC MAX a bit too low to go and get the FL370. The intertropical converence, that's it, we're in it between SALPU and TASIL. Minus 42, we won't use the anti ice, and that's a bonus. See how we are at the limit of the layer ?
PNF: You might want to head a little bit to the left, we agree that I am in manual yeah ?
PNF: What I call in manual ah no we're in calibrated
PF: You want me to set ignition start ?

PNF: What's that ??
<Stall, stall>
PF: we don't have a good... we don't have a good indication...
PNF: We have lost the the the speeds so... Engine thrust ATHR engine lever thrust
PF: Of speed
PNF: Alternate law
PF: Wait we're loosing...
PF: Wing anti-ice
PF: Watch the speed, careful with the speed
PNF: Ok, I'm descending
PF: You stabilize
PNF: Yeah

PF: Touch as little as you can the controls in lateral ok ?
PNF: I'm in TOGA yeah
PF: (...) He's coming or what ?
PNF: But we have the engines, what's going on ?
PF: I've lost control of the airplane there, I've completely lost control of the airplane
PNF: Stick to the left
<Cockpit door opens>
C: Hey what are you guys doing ?
PNF: What's going on ? I don't know what's going on !
<end of stall alarm>
C: Ok here, take that
<stall, stall>
PF: I have a problem, I've got no VSI
C: Ok
PF: I've lost all indications
C: I feel that we are climbing like crazy no ? What do you guys think ?
PF: No, above all don't take them out ! <stall, stall> (nose up at 41 deg)
PF: What do you think about that ? What do you think about that ? What should we do ?
PNF: There I don't know, it's going down
C: Ok, it seems we're back wings level, no it doesn't (want)
PF: Wings level, standy horizon horizon
PNF: Horizon
PNF: Speed ?
<stall, stall>
PF: You're going down, going down, going down
PNF: I'm going down now ?
PF: Down
C: No you're climbing
PF: I'm climbing okay so let's descend
<stall, stall>
PF: Okay we'r in TOGA
<stall, stall>
PF: What do we have altitude ?
C: (...) It can't be
PF: Altitude ?
PNF: How's that, altitude ?
PF: Yeah, yeah, yeah, I'm going down there no ?
C: Hey! You're in... Put the wings level !
PNF: Put the wings level !
PF: That's what I'm trying to do !
PF: I'm all the way to... with left rudder
PNF: The rudder
PF: What the... How is it that we're still descending like crazy ?
PNF: See what you can do with your controls up there the primary etc
PF: Level 100 (10'000ft)
PF: 9000ft
C: Easy with the rudder there
PNF: Climb, climb, climb !!!!!
PF: But I'm all the way nose up since way back !!
C: No, no don't climb !
PNF: Well go down then

PF: Well you'd better be, we're at 4000ft
C: Go, pull
PF: Come on up, up, up
C: 10 degres nose up
<end of recording>
According to the FDR, they were 41 deg nose up most of the descent, and they went from wings level to 40 degres. Poor guys, may they RIP.
