Yes, for the Infinio 70 (as well as for L70, P70 M70) the speech in loud noise could be setup by the fitter as a separate manual program which does not activate automatically.
The fitter have to setup an additional program (e.g. P1) and choose for that the speech in loud noise
Here in the picture you see that for the 70 level are the following additional programs possible
Speech in loud noise , Acustic Phone, Speech in 360° , Mask Program , Custom Program. These are also aqvailable for the 90 level.
Note:
Comfort in Echo has been removed comletley from the whole Infinio line.
The Infinio line has better Bluetooth and ADP 3.0, so I would go for the Infino 70R.
