Does implementation of Augmentative/Alternative Communication support speech development?

Introduction

Augmentative and Alternative Communication (AAC) refers to various methods used to support or replace speech for individuals with communication impairments. This includes manual signs, picture-based systems, and speech-generating devices. The impact of AAC on speech development, particularly whether it supports or hinders speech production, is a critical area of research.

Key Insights

Positive Impact on Speech Production:
- Most studies indicate that AAC interventions do not impede speech production and often result in modest gains in speech .
- A significant majority of participants in various studies showed improvements in speech production following AAC intervention .
No Negative Impact on Speech:
- None of the reviewed cases demonstrated a decrease in speech production due to AAC intervention .
- AAC interventions are generally found to be beneficial or neutral in terms of their impact on speech production .
Modest Gains in Speech:
- While AAC interventions often lead to improvements, the gains in speech production are typically modest and do not surpass the use of AAC itself .
Support for Individuals with Developmental Disabilities:
- AAC technologies can help individuals with intellectual and developmental disabilities (IDD) achieve greater participation and improve their language and communication skills.
- AAC is particularly beneficial for individuals with autism spectrum disorders (ASD), supporting both speech and overall communication abilities .
Broad Applicability:
- AAC is used across a range of conditions, including autism, cerebral palsy, learning difficulties, and acquired neurological conditions .
- It is also effective in supporting communication for individuals with severe communication impairments, providing an essential means of interaction.

Conclusion

The implementation of Augmentative and Alternative Communication (AAC) generally supports speech development rather than hindering it. Most studies report modest gains in speech production, with no evidence of decreased speech due to AAC use. AAC interventions are beneficial across various developmental and acquired conditions, enhancing communication abilities and participation in daily activities.
