s. Tamil does not distinguish phonologically between voiced and unvoiced consonants; phonetically, voice is assigned depending on a consonant's position in a word. Tamil phonology permits few consonant clusters, which can never be word initial. Native grammarians classify Tamil phonemes into vowels, consonants, and a "secondary character", the āytam.

Aspiration (phonetics)
In phonetics, aspiration is the strong burst of air that accompanies either the release or, in the case of preaspiration, the closure of some obstruents. To feel or see the difference between aspirated and unaspirated sounds, one can put a hand or a lit candle in front of one's mouth, and say pin ...

Voice (phonetics)
Voice or voicing is a term used in phonetics and phonology to characterize speech sounds, with sounds described as either voiceless or voiced. The term, however, is used to refer to two separate concepts. Voicing can refer to the articulatory process in which the vocal cords vibrate...

 and the places they can occur do not intersect. For example, the unvoiced plosive 'p' occurs at the beginning of the words and the voiced plosive 'b' cannot. In the middle of words, unvoiced plosives commonly occur as a geminated pair like -pp- , while voiced plosives do not usually come in pairs. Only the voiced plosives occur after a vowel, or after a corresponding nasal. Thus both the voiced and unvoiced plosives can be represented by the same script in Tamil without ambiguity, the script denoting only the place and broad manner of articulation (plosive, nasal

, Tamil did not need separate characters for voiced consonants. A slightly different theory holds that voiced consonants were at one stage allophones of unvoiced consonants, and the lack of distinction between the two in the modern script merely reflects that.
