We communicate by producing speech acts. When we use them in certain communicative situations, we do something else than speaking: we perform an action that may be a request, a question, a promise or a threat; we give information, etc. (Austin, 1962).

John Austin (1911-1960)
- The speech act is the linguistic communication unit and represents the verbal expression of the communicative intent.

Within the ICRA Method, the authors consider that the speech act:
- Is the verbal, grammatically complete, expression of the sender’s communicative intent, decoded by the receiver as coherent with the communicative situation.
- Is made up of paralinguistic, pre-linguistic, linguistic, nonverbal coherence and verbal coherence features, some of which are common to all speech acts and others are specific (distinctive feature).
- Marks a fundamental point for clinical speech and language work: it makes it possible to rank verbal production by its communicative weight beyond vocabulary, since what matters when a patient with communication compromises verbalizes is the impact of communicative functionality and not mere lexical production.
- If a patient makes himself/herself understood through nonverbal resources, this implies that he/she has a suitable nonverbal pragmatic development, but nonetheless faces difficulties in his/her verbal pragmatic competence (Abraham & Brenca, 2016).
