Purpose The aim of this study is to identify the main aspects of the decision-making process indicating the use of Augmentative Alternative Communication (AAC), as well as characteristics of the interventions. Methods This is a prospective study, which was submitted to and approved by the Ethics and Research Committee. An electronic questionnaire was created and sent to speech therapist professionals to collect data for this research, with a minimum of 5 years clinical experience in the AAC area. Results We found a predominance in the clinic, of work with young children, especially in cases of ASD and CAS. There is a divergence in the reporting of the addressed technology and the example of the used resource. Most report difficulties in adherence to AAC, mainly due to lack of understanding what AAC is all about and barriers from family members and other professionals. Conclusion There is a lack of research and professional training in the AAC area. Therefore, investing in these areas is necessary to expand the conscious use of AAC and to promote awareness of other professionals and family members.
