Spoken word boundaries are not written word boundaries
Liaison and elision glue French together: "les amis" is pronounced as one unit, "je ai" becomes "j'ai". The acoustic signal simply does not contain the spaces the written language requires. A French transcript is therefore always partly a grammatical reconstruction, which is why models that understand syntax outperform ones that only match sounds.
