purpose: to verify the applicability of the protocol overall assessment of the speaker's experience of stuttering - adults (oases-a), translated into brazilian portuguese, in a sample of adults who stutter. methods: the brazilian portuguese version of the oases-a protocol was individually applied to 18 people who stutter. the classification of stuttering severity was based on the stuttering severity instrument for children and adults (ssi-3) protocol. translation and back-translation processes were carried out by specialists, considering semantic, conceptual, cultural, and idiomatic equivalences. results: there was no correlation between the severity degrees of stuttering assessed by the ssi-3 protocol and the self-assessment performed using the oases-a. subjects reported impairments in perceived fluency; speech ability; level of knowledge about stuttering and treatment options; use of confrontational techniques; quality of life. they also mentioned having difficulty coping with emotional states such as anxiety and embarrassment, and with communication in daily situations. conclusion: the oases-a protocol is useful in the assessment and treatment of stutterers, as it provides specialized speech-language pathologists with sutterers' self-perception regarding their communication difficulties and the impact of stuttering on their quality of life.
