Why Do Palkids Children Have Such Good Pronunciation?

Pronunciation is not made up only of movements of the mouth and tongue.

Learners need to compare the sounds they produce with the target English sounds and adjust the differences.

For example, if two English sounds are heard as the same sound, it becomes difficult to tell what exactly needs to change.

Conversely, if they can hear the difference between sounds, it becomes easier to check whether their pronunciation is close to the target sound.

In Flege’s (1995) Speech Learning Model, the way second-language sounds are perceived and categorized in relation to first-language sounds is considered deeply connected to second-language pronunciation acquisition.

Likewise, Best and Tyler’s (2007) PAM-L2 explains that the difficulty of distinguishing and acquiring sounds varies depending on how learners map second-language sounds onto native-language sound categories.

In other words, how English sounds are heard cannot be separated from how they are pronounced.

When children grow up in a Japanese-speaking environment, the speech-processing system needed to understand Japanese efficiently develops.

This is a necessary part of acquiring Japanese.

At the same time, when listening to English, the phonological categories and rhythm they have already acquired in Japanese may still exert a strong influence.

As a result, they may perceive English sounds by replacing them with similar Japanese sounds and then pronounce them that way.

The Japanese-like quality that remains in many Japanese learners’ pronunciation cannot be explained only by the shape of the speech organs.

How English speech is perceived and what kinds of sound representations are formed in the mind also plays a major role.

Young children do not primarily learn pronunciation by looking at phonetic symbols and practicing one sound at a time. They imitate what they hear as chunks.

With songs, they reproduce not only individual vowels and consonants, but also the melody, rhythm, stress, and length of sounds.

With picture-book sentences, they may imitate the reader’s intonation and the way words link together, rather than reading each word one by one in a Japanese-like manner.

At first, they are not reconstructing the audio into meaningful grammatical knowledge. Instead, it is more like “copying” the entire stream of speech as one chunk.

However, when stable exposure to English speech has accumulated beforehand, they can more easily reproduce not only vowels and consonants, but also features like the following.

For that reason, entire sentences or songs can sometimes sound more natural than when individual sounds have been practiced mechanically.

One theory that explains speech perception is the Motor Theory of Speech Perception proposed by Liberman and Mattingly (1985).

According to this theory, when people perceive speech, they do not hear it merely as acoustic stimuli. They also perceive the articulatory gestures the speaker intended to make in order to produce those sounds.

That said, Motor Theory is only one of several theories of speech perception, and not all researchers agree with its stronger claims.

There are still various positions today on whether speech perception can be explained purely by auditory analysis and on the extent to which information about speech movements is involved.

Even so, when thinking about pronunciation acquisition, it is important to recognize that listening experience and speech movement interact during learning, and that learners adjust pronunciation while listening to the sounds they themselves produce.

This does not mean that once the ear develops, the mouth automatically becomes perfect

Being able to hear differences between sounds is an important foundation for pronunciation acquisition, but actual pronunciation also requires coordinating movements of the tongue, lips, jaw, breathing, and more.

When children are older and are acquiring a new sound, or when a specific sound is difficult to establish, pronunciation practice that checks mouth shape and tongue position can also be effective.

Infants do not begin life speaking fully formed words.

By repeating babbling and vowel-like vocalizations, listening to their own voices, and responding to the voices of adults around them, their vocalizations gradually become more language-like.

Kuhl and Meltzoff (1996) examined how infants’ vocalizations changed in response to adult vowel sounds in infants aged 12, 16, and 20 weeks.

As a result, infant vowel-like vocalizations showed a tendency to move closer to the acoustic characteristics of the adult vowels they heard, suggesting that vocal imitation may play a role in vocal development.

This is one study showing that even without receiving explicit explanations of how to pronounce sounds, infants can use the speech they hear around them as a guide and change their own vocalizations.

Children’s pronunciation development involves listening, producing sounds themselves, hearing their own voices, and receiving responses from the people around them.

Even among children using Palkids, some cannot pronounce every English sound accurately from the very beginning.

For example, the dental fricative in the English word “three” may at first be pronounced as something closer to “f.”

In the pronunciation development of native English-speaking children, consonants that are still being acquired may also be temporarily replaced with other sounds that are similar in manner or place of articulation.

Smit (1993) organized consonant errors by age among children in the Iowa-Nebraska Articulation Norms Project and reported a variety of substitutions and distortions in fricatives, liquids, and other sounds.

Therefore, if a young child temporarily pronounces “th” as another sound, there is no need to conclude from that alone that the child cannot hear English sounds correctly or that an incorrect pronunciation has become fixed.

However, second-language pronunciation in Japanese-speaking children is not the same as first-language development in native English-speaking children.

Even if similar substitutions are observed, we cannot assume that both groups are going through exactly the same developmental process.

What matters is not correcting each sound immediately, but continuing exposure to accurate English speech and building experiences that let children adjust their own pronunciation.

When people say pronunciation is good, they tend to focus on individual consonants such as being able to distinguish r and l or pronounce th correctly.

However, other factors besides individual sounds also play a major role in whether English as a whole sounds natural.

Even if the sounds within a word are individually correct, if every sound is pronounced with the same strength and length, the English as a whole may sound unnatural.

Conversely, even if some fine consonant details are still developing, if a child can reproduce English rhythm, stress, and intonation as a whole, the English may sound quite natural.

In Palkids, repeatedly listening to songs, stories, and everyday expressions helps children experience not only individual sounds but also the prosody of English as a whole.

In Palkids, pronunciation learning is not completed through audio input alone via background English audio.

First, children are repeatedly exposed to English sounds and rhythm through background English audio.

Next, through online lessons and picture books, they connect the sounds they have been hearing with pictures, situations, and meaning.

Later, when they begin to read text, they connect the English sounds already in their ears with spelling.

If speech representations are formed first, children can map written words to English sounds they already know, rather than assembling English words one character at a time in a Japanese-style pronunciation.

In early childhood, learning can center on hearing accurate English speech and imitating it.

However, when children are older and the influence of print has grown stronger, or when a habit of pronouncing specific sounds in a Japanese way has taken hold, conscious pronunciation practice can also help.

Audio input and pronunciation instruction are not in opposition.

By building target English sounds in the mind through abundant audio input and checking articulatory movements when necessary, children can fine-tune pronunciation in more detail.
