Augmentative and Alternative Communication (AAC) refers to a set of tools and strategies that support or replace verbal communication for individuals with communication disorders, such as Broca's aphasia or other conditions that affect speech and language abilities. AAC is designed to enhance communication and may be used as a temporary or permanent solution, depending on the individual's needs. Here are some key aspects of AAC:

# Communication Aids:
#* Low-Tech AAC: This includes simple, non-electronic communication aids such as communication boards, picture books, or communication charts. Users can point to or select symbols or pictures to convey their messages<ref name="sciencedirect.com" />
#* High-Tech AAC: Involves electronic devices such as speech-generating devices (SGDs) or tablet-based communication apps. These devices use synthesized speech or recorded messages to facilitate communication. Users can select words, phrases, or symbols on a screen to express themselves.
# Symbols and Representations:
#* Symbols used in AAC can vary and may include pictures, icons, words, or a combination of these. Symbols are chosen based on the individual's cognitive and language abilities.
# Types of AAC Systems:
#* Unaided AAC: Relies on the user's body to convey messages without external tools, such as using gestures, facial expressions, or sign language.
#* Aided AAC: Involves external tools or devices, such as communication boards, speech-generating devices, or computer-based systems.
# Vocabulary and Language Systems:
#* Core Vocabulary: Focuses on essential words that are frequently used across various contexts. Core vocabulary systems aim to provide users with a versatile set of words to express a wide range of messages.
#* Fringe Vocabulary: Includes specific words related to an individual's unique needs, interests, or daily activities. Fringe vocabulary supplements core vocabulary to make communication more personalized.<ref name=":5" />
# Customization and Individualization:
#* AAC systems are highly customizable to meet the unique needs of each user. Therapists work with individuals and their families to tailor the system to the user's abilities, preferences, and communication goals.
# Training and Support:
#* Users of AAC systems, as well as their caregivers and support networks, receive training to effectively use the communication tools. Training may involve learning how to navigate electronic devices, program personalized messages, or understand the meaning of symbols.
# Integration with Therapy:
#* AAC is often integrated into speech and language therapy sessions. Therapists use AAC tools to facilitate communication practice and help individuals with communication disorders improve their language skills.<ref name="Nakai_2017" />
# Social and Emotional Aspects:
#* AAC not only addresses the functional aspects of communication but also considers the social and emotional dimensions. It plays a crucial role in helping individuals with communication disorders participate more fully in social interactions and express their thoughts and feelings.

AAC is a dynamic and evolving field, and advancements in technology continue to enhance the range and effectiveness of communication tools available for individuals with speech and language challenges. The selection of AAC strategies depends on factors such as the individual's abilities, preferences, and the specific nature of their communication disorder.
