Despite the phonetic changes in the spoken dialects since the script was fixed, the Tibetans have never changed their system of writing.
These regions were not activated in the dyslexic group in which activation was observed for acoustic but not phonetic changes in stimuli.
First, we examined whether TMS-induced disruptions in the motor system modulate MMN responses to phonetic changes in speech sounds.
The MMN responses to phonetic changes in speech sounds are enhanced for phonetic contrasts in the perceiver's native language (Näätänen et al. 1997; Winkler et al. 1999; Diaz et al. 2008).
Next, we examined whether disruption of the motor lip representation also modulates MMN responses to acoustic (i.e. non-phonetic) changes in speech sound sequences and whether these modulations are specific to speech.
In addition to phonetic changes (Experiment 1), TMS-induced disruption in the articulatory motor cortex affected MMN responses to changes in intensity, but not to changes in duration, in a sequence of "da" sounds (Experiment 3).
A restricted region of left posterior STG responds preferentially to trials containing a phonetic change (DEV) in comparison with trials containing no phonetic change (STD), as shown in Figure 2.
The Hungarian form Kolozsvár, first recorded in 1246 as Kulusuar, underwent various phonetic changes over the years (uar/vár means "castle" in Hungarian); the variant Koloswar first appears in a document from 1332.
Therefore, we can conjecture to identify the phonetic changes through observing the kernel adaptive filter behavior.
However, further investigation is required to elucidate whether AOB leads to phonetic changes or phonetic alterations cause AOB.
