9 Ways Speaking A Second Language Can Impact A Child's Speech Development

Enhancing their cognitive flexibility

The process of learning two language systems at once strengthens a child’s executive function, including skills like making decisions and following directions. This means that not only can they understand and manipulate language rules more fluidly but they often display better cognitive flexibility. 

As a result, they may also find it easier to switch between tasks and adapt to new rules in other aspects of their life. 

The trouble is, when a child is early in their bilingual journey, they may experience something known as ‘code-switching’. This is when they alternate between languages mid-sentence, and it can sometimes appear as if they are confused or experiencing a delay in language consistency. 

Thankfully, this is usually only a temporary problem. 

Expanding their vocabulary 

As they learn words in two languages, bilingual children are exposed to a much broader vocabulary. Over time, this can result in a richer vocabulary across both languages.

That said, early on, this could mean that the child knows fewer words in each language in comparison to their monolingual peers. This is because their vocabulary is being spread between two languages. 

The good news is that the gap usually closes with consistent exposure to both languages and in the end, they build a broader vocabulary. 

Improving their phonological awareness

Learning a second language can improve a child's phonological awareness. It improves their ability to recognise and manipulate sounds in words, a skill that is important for reading and writing. This makes it easier for them to distinguish sounds and patterns across languages.

On the other hand, phonological interference may occur when learning two languages, as sounds from one language can affect their pronunciation in the other language. For example, a child might struggle with specific sounds that exist in one language but not the other. 

This can impact their speech clarity temporarily but will improve their phonological awareness over time.

Causing potential delays or silent periods 

Although this is not always the case, bilingual children can sometimes reach certain language milestones slightly later than monolingual children. For example, they may speak their first words or form their first sentences slightly later than their peers. 

However, this difference is usually fairly minor and, in most cases, does not lead to a bigger developmental delay. Then, when bilingual children catch up, both of their languages are strengthened.

Not only this, but bilingual children, especially in the early stages of language acquisition, may go through silent periods. 

This usually happens because they are listening and processing language rather than speaking it. However, this is a natural phase as they adjust to new sounds and vocabulary. Although it may look like a speech delay, it typically resolves itself as their confidence in their speaking abilities grows.

Increasing their ability to learn additional languages 

Learning a second language at an early age makes it easier for children to learn additional languages later on. This is possible as their brain becomes accustomed to learning new language structures, which can improve their adaptability. 

The tricky part is, if their language exposure is inconsistent, they may struggle with fluency. As a result, they may only retain a passive understanding of a second language. What this means is that although they may understand the second language, they could feel uncomfortable speaking it.

But for the most part, being bilingual opens the gates to being multilingual later in life. 

Encouraging speech development in children 

Strengthening their metalinguistic skills

Metalinguistics is the study of how language is used to understand, discuss, and analyse itself and bilingual children tend to develop stronger metalinguistic awareness. They have a better ability to think about and analyse language itself. 

This can strengthen their grammar and comprehension skills as they grow, helping them understand language structures intuitively.

The trouble is that initially, a bilingual child might mix grammatical structures from both languages. Again, this can look like a language delay. However, this is typically a natural stage in their speech development as the child is learning to separate language systems, and delays will pass.

Improving social and cultural understanding 

Speaking two languages allows children to engage with different cultural contexts. This not only enhances their social skills and cultural awareness but it can also improve their communication skills as they learn to adapt language and behaviour based on cultural cues.

Enhancing their problem-solving and critical thinking

Following on from this, the process of managing two languages can enhance a child’s problem-solving and critical-thinking skills. This is possible because bilingual children learn to think more flexibly, often leading to stronger problem-solving abilities. 

Strengthening these skills can positively impact their language use and comprehension. However, 

the process of juggling two language systems can lead to processing lags, where a child may need more time to find the right word in one language. This may get worse when they feel stressed or tired. 

Bridging Language Needs in Official Contexts

For bilingual children from immigrant backgrounds, having access to official documents, such as a Mexican birth certificate, if they were born in Mexico, can also play a role in reinforcing their language skills. When these documents are presented in the home language, children may develop a sense of pride and a stronger connection to their cultural heritage. This exposure to formal language can also help bilingual children understand the importance of their linguistic background in real-world contexts, potentially inspiring them to maintain fluency in both languages.

Understanding Support for Bilingual Development

Raising a bilingual child provides a wide array of cognitive, social, and academic advantages. However, there are practical considerations to account for, particularly when it comes to documentation and educational resources. Many parents of bilingual children encounter translation needs early on, whether it's translating school transcripts, medical records, or other important documents to ensure seamless communication with educators and healthcare providers.

Translation costs can vary significantly based on factors such as the complexity of the text, the language pair, and the level of certification required. For example, translations needed for official purposes, such as school admissions or legal proceedings, often require certified or sworn translators, which can increase costs. While these expenses may add up, they play a crucial role in bridging communication gaps and ensuring that a child’s bilingual journey is supported effectively in both languages.

Moreover, as bilingual children often access resources in multiple languages, parents may also invest in translated educational materials, which can range from books and learning aids to multimedia resources. These resources help reinforce language skills, enhance vocabulary in both languages, and support overall language development, but they do come with their own costs. Understanding these potential expenses can help families plan ahead and allocate resources to maximise their child’s exposure to both languages without unnecessary financial strain.

Being aware of translation costs can be empowering, allowing parents to make informed choices that not only support their child’s language development but also foster a balanced bilingual environment. After all, consistent access to language resources in both languages helps children navigate and excel in diverse linguistic and cultural contexts, enhancing their speech development and cognitive flexibility over time.

In summary 

Learning a second language has a number of benefits, including cognitive, social and linguistic benefits. 

Although it can present some unique challenges during the learning process, these are only temporary setbacks. If a child struggles with their vocabulary, processing or missing key milestones, these issues are typically only short-term as they adapt to both language systems. 

With consistent exposure and support to both languages, bilingual children can grow into well-rounded communicators. 

They can improve their phonological awareness and cognitive flexibility and enhance their vocabulary. By strengthening these skills, they can also increase their ability to learn additional languages in the future.
