<p>L&rsquo;objectif de cet article est de mettre en lumi&egrave;re les ph&eacute;nom&egrave;nes hors-normes qui r&eacute;gissent le discours int&eacute;rieur. Cet objet linguistique par essence insaisissable et inobservable invite &agrave; repenser les normes d&rsquo;analyse scientifique&nbsp;afin de d&eacute;velopper des outils sp&eacute;cifiques d&rsquo;analyse du discours qui s&rsquo;&eacute;cartent du discours communicationnel oral et/ou &eacute;crit. Le discours int&eacute;rieur constitue l&rsquo;envers du discours ext&eacute;rioris&eacute;, &agrave; l&rsquo;&eacute;crit et/ou &agrave; l&rsquo;oral, et la vari&eacute;t&eacute; de ses repr&eacute;sentations t&eacute;moigne de l&rsquo;impossibilit&eacute; de formalisation du discours int&eacute;rieur. A cet &eacute;gard, la repr&eacute;sentation endophasique qu&rsquo;&eacute;labore Hermann Broch dans Der Tod des Vergil remet en question les normes et conventions textuelles et morphosyntaxiques. Ni le paragraphe, ni la phrase ne semble&nbsp;ainsi les unit&eacute;s linguistiques pertinentes pour l&rsquo;analyse de l&rsquo;endophasie, qui n&rsquo;est pas organis&eacute;e autour de ph&eacute;nom&egrave;nes visuels et scripturaux, mais davantage autour de ph&eacute;nom&egrave;nes d&rsquo;&eacute;coute (polyphonie, rythme, r&eacute;p&eacute;titions).</p> <p>&nbsp;</p> <p>The aim of this article is to highlight the non-standard phenomena that govern inner speech. This linguistic object, which can&rsquo;t be directly observed, challenges the norms and methods of its study. We need to develop specific methods for the analysis of inner speech that differs from the one we use for oral and/or written communicative discourse. The inner speech constitutes the other, hidden side of the externalized speech, written and/or oral speech, and the variety of its representations shows the impossibility of its formalization. Therefore, the representation of inner speech that Hermann Broch elaborates in Der Tod des Vergil questions the textual and morphosyntactic norms and conventions. Neither the paragraph nor the sentence seem to be a relevant linguistic unit for the analysis of inner speech. Instead, the focus lies on rhythm and acoustic phenomena, which are two essential features of inner speech</p>
