The voice consists of sound made by a human being using the vocal folds for talking, singing, laughing, crying, screaming, etc. The human voice is specifically that part of human sound production in which the vocal folds (vocal cords) are the primary sound source. Generally speaking, the mechanism for generating the human voice can be subdivided into three parts; the lungs, the vocal folds within the larynx, and the articulators. The lung (the pump) must produce adequate airflow and air pressure to vibrate vocal folds (this air pressure is the fuel of the voice). The vocal folds (vocal cords) are a vibrating valve that chops up the airflow from the lungs into audible pulses that form the laryngeal sound source. The muscles of the larynx adjust the length and tension of the vocal folds to ‘fine tune’ pitch and tone. The articulators (the parts of the vocal tract above the larynx consisting of tongue, palate, cheek, lips, etc.) articulate and filter the sound emanating from the larynx and to some degree can interact with the laryngeal airflow to strengthen it or weaken it as a sound source.
The vocal folds, in combination with the articulators, are capable of producing highly intricate arrays of sound. The tone of voice may be modulated to suggest emotions such as anger, surprise, or happiness. Singers use the human voice as an instrument for creating music.
The Malayalam script (Malayalam: മലയാളലിപി, Malayāḷalipi, IPA: [mɐləjaːɭɐ lɪβɪ] ( )) is a Brahmic script used commonly to write the Malayalam language—which is the principal language of the Indian state of Kerala, spoken by 35 million people in the world. Like many other Indic scripts, it is an abugida, or a writing system that is partially “alphabetic” and partially syllable-based. The modern Malayalam alphabet has 13 vowel letters, 36 consonant letters, and a few other symbols. The Malayalam script is a Vattezhuttu script, which had been extended with Grantha script symbols to represent Indo-Aryan loanwords. The script is also used to write several minority languages such as Paniya, Betta Kurumba, and Ravula. The Malayalam language itself was historically written in several different scripts.
Tolkāppiyam, the earliest available work in Tamil, is divided into three parts each into nine chapters. The first two parts deal with the Tamil language and the third with its literature.
The very first chapter deals with the arrangement of characters.
The second one explains the depending letters occurring only in words.
It extends its views on the structural pattern of the words with their initial and ending phonemes. Assimilation of these three with other phonemes is also dealt here.
A social issue (also called a social problem or a social situation) is an issue that relates to society's perception of a person's personal lives. Different cultures have different perceptions and what may be "normal" behavior in one society may be a significant social issue in another society. Social issues are distinguished from economic issues. Some issues have both social and economic aspects, such as immigration. There are also issues that don't fall into either category, such as wars.
Thomas Paine, in Rights of Man and Common Sense, addresses man's duty to "allow the same rights to others as we allow ourselves". The failure to do so causes the birth of a social issue.
