Tone Terracing
Tone terracing is a type of phonetic downdrift, where the high or mid tones, but not the low tone, shift downward in pitch ( downstep) after certain other tones. The result is that a tone may be realized at a certain pitch over a short stretch of speech shifts downward, then continues at its new level and then shifts downward again until the end of the prosodic contour is reached, at which point the pitch resets. A graph of the change in pitch over time of a particular tone resembles a terrace. Since the pitch of the low tone remains more-or-less constant at the lower end of the speaker's vocal range, and the other tones shift downward, the difference in their pitches narrows, eventually obscuring the tones altogether. Pitch reset is then required if the tone system is to continue to function. Tone terracing is particularly common in the languages of West Africa, where typically only the low tone causes downstep. However, a somewhat more intricate system is found in the Twi la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonetics
Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians. The field of phonetics is traditionally divided into three sub-disciplines on questions involved such as how humans plan and execute movements to produce speech (articulatory phonetics), how various movements affect the properties of the resulting sound (acoustic phonetics) or how humans convert sound waves to linguistic information (auditory phonetics). Traditionally, the minimal linguistic unit of phonetics is the phone (phonetics), phone—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones and it is also defined as the smallest unit that discerns meaning between sounds in any given language. Phonetics deals with two aspects of human speech: production ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Downdrift
In phonetics, downdrift (also known as ''automatic downstep'') is the cumulative lowering of pitch in the course of a sentence due to interactions among tones in a tonal language. Downdrift often occurs when the tones in successive syllables are H L H (high, low, high) or H L L H (high, low, low, high). In this case the second high tone tends to be lower than the first. The effect can accumulate so that with each low tone, the pitch of the high tones becomes slightly lower, until the end of the intonational phrase, when the pitch is "reset". However, not every sequence of H L H leads to downdrift. In some languages, in some circumstances, the two high tones in a sequence H L H can be pronounced on the same level, with a "plateau" between them; that is, H L H changes to H H H. This occurs for example in Chichewa if the first H is a proclitic word, e.g. "of" + "Malawi" is pronounced "of Malawi", with a plateau. In other languages, in some circumstances, even longer sequences suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tone (linguistics)
Tone is the use of pitch (music), pitch in language to distinguish lexical or grammatical meaning—that is, to distinguish or to inflection, inflect words. All oral languages use pitch to express emotional and other para-linguistic information and to convey emphasis, contrast and other such features in what is called intonation (linguistics), intonation, but not all languages use tones to distinguish words or their inflections, analogously to consonants and vowels. Languages that have this feature are called tonal languages; the distinctive tone patterns of such a language are sometimes called tonemes, by analogy with ''phoneme''. Tonal languages are common in East Asia, East and Southeast Asia, Africa, the Americas, and the Pacific islands, Pacific. Tonal languages are different from pitch-accent languages in that tonal languages can have each syllable with an independent tone whilst pitch-accent languages may have one syllable in a word or morpheme that is more prominent t ...

Downstep (phonetics)
Downstep is a phenomenon in tone languages in which if two syllables have the same tone (for example, both with a high tone or both with a low tone), the second syllable is lower in pitch than the first. Two main kinds of downstep can be distinguished. The first, more usually called automatic downstep, downdrift or catathesis, occurs when high and low tones come in the sequence H L (L) H; the second high tone tends to be lower than the first because of the intervening low-toned syllable. It is common in African languages, such as Chichewa. It has also been argued that the same phenomenon is heard in English sentences, if these sentences are pronounced with a falling intonation, for example ''I really believe Ebenezer was a dealer in magnesium'', or ''I bought blueberries, bayberries, raspberries, mulberries, and brambleberries''. Downstep proper, or non-automatic downstep, is another phenomenon found in many African languages, such as Igbo (see for an overview of downstep in ...

Prosodic Unit
In linguistics, a prosodic unit is a segment of speech that occurs with specific prosodic properties. These properties can be those of stress, intonation (a single pitch and rhythm contour), or tonal patterns. Prosodic units occur at a hierarchy of levels, from the syllable, the metrical foot and phonological word to the intonational unit (IU) and to a complete utterance. However, the term is often restricted to intermediate levels which do not have a dedicated terminology. Prosodic units do not generally correspond to syntactic units, such as phrases and clauses; it is thought that they reflect different aspects of how the brain processes speech, with prosodic units being generated through on-line interaction and processing, and with morphosyntactic units being more automated. Defining characteristics Prosodic units are characterized by several phonetic cues, such as pitch movement, pre-boundary lengthening, and pauses.

Pitch Reset
In speech, phonetic pitch reset occurs at the boundaries (pausa) between prosodic units. Over the course of such units, the median pitch of the voice declines from its initial value, sometimes reaching the lower end of the speaker's vocal range. Then, it must reset to a higher level if the person is to continue speaking. In non-tonal languages, the sudden increase in pitch is one of the principal auditory cues to the start of a new prosodic unit. In register tone languages which experience discrete downdrift, pitch reset is required as the tones approach the lower end of the speaker's comfort range, and in those languages which experience tone terracing, it is in addition required in order to maintain the tonal distinctions of the language. See also * Upstep In linguistics, upstep is a phonemic or phonetic upward shift of tone between the syllables or words of a tonal language. It is best known in the tonal languages of Sub-Saharan Africa. Upstep is a much rarer phenomenon tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terrace (agriculture)
A terrace in agriculture is a flat surface that has been cut into hills or mountains to provide areas for the cultivation for crops, as a method of more effective farming. Terrace agriculture or cultivation is when these platforms are created successively down the terrain in a pattern that resembles the steps of a staircase. As a type of landscaping, it is called terracing. Terraced fields decrease both erosion and surface runoff, and may be used to support growing crops that require irrigation, such as rice. The Rice Terraces of the Philippine Cordilleras have been designated as a UNESCO World Heritage Site because of the significance of this technique. Uses Terraced paddy fields are used widely in rice, wheat and barley farming in East Asia, east, South Asia, south, Western Asia, southwest, and southeast Asia, as well as the Mediterranean Basin, Africa, and South America. Drier-climate terrace farming is common throughout the Mediterranean Basin, where they are used for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Twi Language
Twi (; ) is the common name of the Akan literary language of Asante and Akuapem. Effectively, it is a synonym for 'Akan' that is not used by the Fante people. It is not a linguistic grouping, but more of a common name used by inland Akans as Akuapem Twi is more closely related to the Fante dialects than it is to Asante Twi. Aside from the Fante, other Akan groups such as the Nzema, Ahanta, Chakossi, Sefwi, and Baoulé, all classified under the Akan Bia languages, do not use Twi as the name of their languages. Twi generally subsumes the following Akan tongues: Ahafo, Akuapem, Akyem, Asante, Assin, Bono, Denkyira and Kwawu, which have about 4.4 million speakers in southern and central Ghana Ghana, officially the Republic of Ghana, is a country in West Africa.

Ghana
Ghana, officially the Republic of Ghana, is a country in West Africa. It is situated along the Gulf of Guinea and the Atlantic Ocean to the south, and shares borders with Côte d’Ivoire to the west, Burkina Faso to the north, and Togo to the east. Ghana covers an area of , spanning diverse ecologies, from coastal savannas to tropical rainforests. With nearly 35 million inhabitants, Ghana is the second-most populous country in West Africa. The capital and largest city is Accra; other significant cities include Tema, Kumasi, Sunyani, Ho, Cape Coast, Techiman, Tamale, and Sekondi-Takoradi. The earliest kingdoms to emerge in Ghana were Bonoman in the south and the Kingdom of Dagbon in the north, with Bonoman existing in the area during the 11th century. The Asante Empire and other Akan kingdoms in the south emerged over the centuries. Beginning in the 15th century, the Portuguese Empire, followed by other European powers, contested the area for trading r ...

Japanese Pitch Accent
Japanese pitch accent is a feature of the Japanese language that distinguishes words by accenting particular morae in most Japanese dialects. The nature and location of the accent for a given word may vary between dialects. For instance, the word for "river" is in the Tokyo dialect, with the accent on the second mora, but in the Kansai dialect it is . A final or is often devoiced to or after a downstep and an unvoiced consonant. The Japanese term is , and it refers to pitch accent in languages such as Japanese and Swedish. It contrasts with , which refers to stress. An alternative term is which contrasts with . Standard Japanese Normative pitch accent, essentially the pitch accent of the Tokyo Yamanote dialect, is considered essential in jobs such as broadcasting. The current standards for pitch accent are presented in special accent dictionaries for native speakers such as the ''Shin Meikai Nihongo Akusento Jiten'' () and the ''NHK Nihongo Hatsuon Akusento Ji ...
