As parents, it’s natural to notice how your child talks and to wonder whether their speech is developing as expected. If your child is hard to understand or struggles to say certain sounds, you may have heard the term “speech sound disorder.” But what does that mean? Let’s break it down together.
A speech sound disorder (SSD) happens when a child has difficulty producing sounds correctly. Every child makes speech mistakes as they learn to talk—this is a normal part of development. For example, many toddlers say “tat” instead of “cat” or “wabbit” instead of “rabbit.”
There are two broad categories of speech sound disorders:
Sometimes, children may show a combination of both.
You may want to consider a speech evaluation if your child:
The good news: with speech therapy, children can make tremendous progress! Therapy is tailored to your child’s specific needs, but it usually involves:
For bilingual children, speech sound development can look different. Some errors are perfectly normal when learning two languages. That’s why it’s important to work with a bilingual speech-language pathologist who understands how languages interact and can tell the difference between a language difference and a true disorder.
If you’re worried about your child’s speech, you’re not alone.
At Bilingual Speechie LLC, we specialize in helping bilingual and multilingual children find their voice—in every language they speak. If you’d like to learn more or schedule an evaluation contact us today.

When parents hear the word “stuttering,” it can bring up worry or fear about their child’s future. For many years, stuttering was viewed only as a “problem to fix.” But today, new research and approaches help us see stuttering in a different, more affirming way—one that celebrates communication in all its forms and embraces verbal diversity.

As parents, we celebrate every new word, every little sound, and every funny phrase our children come up with. But sometimes, you may find yourself wondering: “Should my child be talking more by now?” or “Is this a sign of a speech delay?”

About the Owner:
Liliana Diaz-Vazquez is a certified licensed bilingual speech language pathologist (SLP), currently practicing in Chicago, Illinois. She obtained her bachelor’s degree in communication disorders (2012) and her master’s degree in speech language pathology at Saint Xavier University (2014). She is a certified member of the American Speech-Language and Hearing Association (ASHA) since 2014, a member of the Illinois Speech and Hearing Association (ISHA) since 2014 and maintains licensure in the state of Illinois.
Liliana is a first-generation Mexican-American Latina, a small business owner, a full-time school-based SLP, & a bilingual parent, who takes pride in her roots, culture, & heritage language. She loves being able to share her experience as a Latina SLP, and a bilingual mom, as well as her culture & heritage language with the educator, SLP, and parent community.
Liliana Diaz-Vazquez has extensive experience working with the bilingual English and Spanish speaking population & multilingual population. She specializes in augmentative/alternative communication (AAC), bilingual language development and language delays/disorders in bilingual/multilingual children. She has also worked in the early intervention setting for several years where she gained vast experience working with interpreters and bilingual/multilingual families.
Liliana began creating digital bilingual resources and activities in 2014 out of need while working full-time in the school setting as a SLP. Liliana worked with many Spanish-speaking families and quickly realized that there were limited Spanish and bilingual speech therapy resources available for her students and their families. In addition, Liliana quickly became aware that there was a need for education about bilingualism and typical bilingual language development as many of the families she worked with had encountered misinformation about bilingualism. Liliana began developing resources and eventually started Bilingual Speechie LLC with the mission to provide education to SLPs and families about bilingualism, as well as provide inclusive and diverse materials for speech therapy in order to help bilingual families and SLPs gain access to appropriate bilingual materials for children with communication disorders.
Today Liliana currently works full-time in the Chicago public school setting as a lead bilingual SLP where she consults and collaborates with SLPs daily to help them understand how to assess and provide culturally and linguistically appropriate services for bilingual and/or multilingual students. She also runs her small business, Bilingual Speechie LLC, and is on a mission to expand and grow her business so that all SLPs, educators, and families can have access to inclusive, diverse, and bilingual resources in a variety of languages for speech therapy.
