The rising prevalence of speech and language disorders, along with heightened awareness and early diagnosis are noteworthy factors contributing to the expansion of the speech and language disorder market size. Additionally, the growing focus on bilingual speech therapy is projected to bring new speech and language disorder market trends in the near future.

As people moved, populations diversified. Speech-language pathologists (SLPs) have long recognized the need for therapy approaches tailored to bilingual and multilingual clients. This has been a reflection of demographic changes that address demands posed by bilingual clients and not fully met by monolingual therapy. Bilingual speech therapy deals with the diagnosis and treatment of speech and language disorders in people who speak two or more languages. Such therapy, unlike its monolingual counterpart, usually requires special knowledge of the languages involved and the slight cultural differences that influence communication.

One major issue that contributes to the growing number of bilingual children with speech-language disorders is the increasing Hispanic population in the US, hence heightened demand for Spanish-English dual-language therapy. Schools and clinical sites are continuing the wide implementation of bilingual therapy models to ensure fair access to effective treatment. The bilingual SLP may work on the allophone articulation of a child in two languages or support language development that strengthens cognition and social skills in other contexts of those two languages.

Therapists practicing bilingualism will hopefully render a more inclusive and effective service, leading to better outcomes for a diverse population to meet the needs of today's multilingual world. An improved role is played by technology toward the improvement of bilingual speech therapy. Software and applications are being made to provide bilingual functionalities for customized therapy exercises that are environmentally considerate of the client language background. This focus on bilingual speech therapy could be a step forward for the industry and are expected to emerge as a significant trend in the speech and language disorder market.
