International Phonetic AlphabetThe International Phonetic Alphabet (IPA) is an alphabetic system of phonetic notation based primarily on the Latin script. It was devised by the International Phonetic Association in the late 19th century as a standardized representation of speech sounds in written form. The IPA is used by lexicographers, foreign language students and teachers, linguists, speech–language pathologists, singers, actors, constructed language creators, and translators.
Voice (phonetics)Voice or voicing is a term used in phonetics and phonology to characterize speech sounds (usually consonants). Speech sounds can be described as either voiceless (otherwise known as unvoiced) or voiced. The term, however, is used to refer to two separate concepts: Voicing can refer to the articulatory process in which the vocal folds vibrate, its primary use in phonetics to describe phones, which are particular speech sounds. It can also refer to a classification of speech sounds that tend to be associated with vocal cord vibration but may not actually be voiced at the articulatory level.
VowelA vowel is a syllabic speech sound pronounced without any stricture in the vocal tract. Vowels are one of the two principal classes of speech sounds, the other being the consonant. Vowels vary in quality, in loudness and also in quantity (length). They are usually voiced and are closely involved in prosodic variation such as tone, intonation and stress. The word vowel comes from the Latin word vocalis, meaning "vocal" (i.e. relating to the voice).
Armenian languageArmenian (հայերեն (reformed), հայերէն (classical), hayeren, hɑjɛˈɾɛn) is an Indo-European language and the sole member of an independent branch of that language family. It is the native language of the Armenian people and the official language of Armenia and the unrecognized Republic of Artsakh. Historically spoken in the Armenian highlands, today Armenian is widely spoken throughout the Armenian diaspora. Armenian is written in its own writing system, the Armenian alphabet, introduced in 405 AD by the priest Mesrop Mashtots.
Yoruba languageYoruba (IPA: /jōrùbá/, UKˈjɒrʊbə, USˈjɒrəbə; Yor. Èdè Yorùbá; Ajami: عِدعِ يوْرُبا) is a language spoken in West Africa, primarily in Southwestern and Central Nigeria. It is spoken by the ethnic Yoruba people. The number of Yoruba speakers is roughly 50 million, plus about 5 million second-language speakers. As a pluricentric language, it is primarily spoken in a dialectal area spanning Nigeria, Benin, and Togo with smaller migrated communities in Côte d'Ivoire, Sierra Leone and The Gambia.
