Diphone
In phonetics, a diphone is an adjacent pair of phones in an utterance. For example, in aɪfəʊn the diphones are a ɪ �f ə �ʊ �n The term is usually used to refer to a recording of the transition between two phones. In the following diagram, a stream of phones are represented by P1, P2, etc., and the corresponding diphones are represented by D1-2, D2-3, etc.: , P1, P2, P3, P4, P5, P6, , D1-2=, D2-3=, D3-4=, D4-5=, D5-6=, If the number of phones in a language is P, the theoretical number of possible diphones is P2. However, since all languages have restrictions about what sounds can occur next to each other (see ''phonotactics''), the number of diphones in each language is usually much smaller than P2. Spanish has about 800 diphones and German about 2,500. Diphones are useful in speech synthesis. When pre-recorded diphones are combined to create synthesized speech, the resulting sounds are much more natural than just combining simple phones. That is because t ...

Speech Synthesis
Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech. The reverse process is speech recognition. Synthesized speech can be created by concatenating pieces of recorded speech that are stored in a database. Systems differ in the size of the stored speech units; a system that stores phones or diphones provides the largest output range, but may lack clarity. For specific usage domains, the storage of entire words or sentences allows for high-quality output. Alternatively, a synthesizer can incorporate a model of the vocal tract and other human voice characteristics to create a completely "synthetic" voice output. The quality of a speech synthesizer is judged by its similarity ... [...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 based on the research 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—a speech sound in a language which differs from the phonological unit of phoneme; the phoneme is an abstract categorization of phones. Phonetics deals with two aspects of human speech: production—the ways humans make sounds—and perception—the way speech is understood. The communicative moda ...

Phone (phonetics)
In phonetics and linguistics, a phone is any distinct speech sound or gesture, regardless of whether the exact sound is critical to the meanings of words. In contrast, a phoneme is a speech sound in a given language that, if swapped with another phoneme, could change one word to another. Phones are absolute and are not specific to any language, but phonemes can be discussed only in reference to specific languages. For example, the English words ''kid'' and ''kit'' end with two distinct phonemes, and , and swapping one for the other would change one word into a different word. However, the difference between the sounds in ''pun'' (, with aspiration) and ''spun'' (, without aspiration) never affects the meaning or identity of a word in English. Therefore, cannot be replaced with (or vice versa) and thereby convert one word to another. That causes and to be two distinct phones but not distinct phonemes in English. In contrast to English, swapping the same two sounds in Hindu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phonotactics
Phonotactics (from Ancient Greek "voice, sound" and "having to do with arranging") is a branch of phonology that deals with restrictions in a language on the permissible combinations of phonemes. Phonotactics defines permissible syllable structure, consonant clusters and vowel sequences by means of ''phonotactic constraints''. Phonotactic constraints are highly language-specific. For example, in Japanese, consonant clusters like do not occur. Similarly, the clusters and are not permitted at the beginning of a word in Modern English but are in German and Dutch (in which the latter appears as ) and were permitted in Old and Middle English. In contrast, in some Slavic languages and are used alongside vowels as syllable nuclei. Syllables have the following internal segmental structure: * Onset (optional) * Rhyme (obligatory, comprises nucleus and coda): ** Nucleus (obligatory) ** Coda (optional) Both onset and coda may be empty, forming a vowel-only syllable, or alternativ ...

Spanish Language
Spanish ( or , Castilian) is a Romance language of the Indo-European language family that evolved from colloquial Latin spoken on the Iberian peninsula. Today, it is a global language with more than 500 million native speakers, mainly in the Americas and Spain. Spanish is the official language of 20 countries. It is the world's second-most spoken native language after Mandarin Chinese; the world's fourth-most spoken language overall after English, Mandarin Chinese, and Hindustani (Hindi-Urdu); and the world's most widely spoken Romance language. The largest population of native speakers is in Mexico. Spanish is part of the Ibero-Romance group of languages, which evolved from several dialects of Vulgar Latin in Iberia after the collapse of the Western Roman Empire in the 5th century. The oldest Latin texts with traces of Spanish come from mid-northern Iberia in the 9th century, and the first systematic written use of the language happened in Toledo, a prominent c ...

German Language
German ( ) is a West Germanic language mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italian province of South Tyrol. It is also a co-official language of Luxembourg and Belgium, as well as a national language in Namibia. Outside Germany, it is also spoken by German communities in France ( Bas-Rhin), Czech Republic ( North Bohemia), Poland (Upper Silesia), Slovakia ( Bratislava Region), and Hungary (Sopron). German is most similar to other languages within the West Germanic language branch, including Afrikaans, Dutch, English, the Frisian languages, Low German, Luxembourgish, Scots, and Yiddish. It also contains close similarities in vocabulary to some languages in the North Germanic group, such as Danish, Norwegian, and Swedish. German is the second most widely spoken Germanic language after English, which is also a West Germanic language. Germ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triphone
In linguistics, a triphone is a sequence of three consecutive phonemes. Triphones are useful in models of natural language processing where they are used to establish the various contexts in which a phoneme can occur in a particular natural language.
