In one of the reading texts, the speaker sounds like he is pronouncing 'fiche' like 'fizh' (or something like that). I listened to it several times and it sounds like he is sometimes softening the 'ch' sound in that word. Is that standard? He does it in the phrase 'vous pouvez faire des fiches de grammaire. I don't think he does this in other occurrences of the word. Thanks.
