Hello Aleix,

The Pāṇinīyaśikṣā says: 
स्वरतः कालतः स्थानात् प्रयत्नानुप्रदानतः। इति वर्णविदः प्राहुर्निपुणास्तं निबोधत।

For your interest, you should consult the Śikṣā and Prātiśākhya literature. A good introduction will be W.S. Allen's book "Phonetics in Ancient India." For details, you may consult the Introduction to my edition of the Śaunakīya Caturādhyāyikā published in the Harvard Oriental Studies. The bibliography in that book may give you comprehensive references to research publications on this subject.

Dear list,

I am looking for scholarly publications on the criteria for the sequential order of the akṣaras in Sanskrit and Pali. I am also interested in knowing if anyone has come across the concepts of kāla (= long, short, etc.) and śruti (voiced, unvoiced, etc.) in relation to the categorisation of akṣaras in Sanskrit śāstras. Especially the concept of kālaśrutibheda, which is what distinguishes sounds generated in the same place of articulation.

Any help will be most appreciated.

Best wishes,
Aleix
