Commentary
Given assumption that Erectus had limited control over मात्रा and स्वरितत्व and absence of आ , Originally these were pronounced as - द अ य अ अ य अ अ स अ श च. entire thing could have taken 3 to 4 breath cycles as per my estimation based on average length of धातु being 2/3 वर्ण. No wonder लाघव was very important, not only from memory perspective but also effort per communication point of view also.
