Wavetable synthesis Wavetable synthesis is used in certain digital music synthesizers to implement a restricted form of real-time additive synthesis . The technique was first developed by Wolfgang Palm of PPG in the late 1970s and published in 1979 [ 2 ] , and has since been used as the primary synthesis method in synthesizers built by PPG and Waldorf Music and as an auxiliary synthesis method by Sequential Circuits , Ensoniq , Korg , Access and Dave Smith Instruments among others.

Phoneme A phoneme is a basic unit of a language 's phonology , which is combined with other phonemes to form meaningful units such as words or morphemes . The phoneme can be described as "The smallest contrastive linguistic unit which may bring about a change of meaning". [ 1 ] In this way the difference in meaning between the English words kill and kiss is a result of the exchange of the phoneme /l/ for the phoneme /s/. Two words that differ in meaning through a contrast of a single phoneme are called minimal pairs . Within linguistics there are differing views as to exactly what phonemes are and how a given language should be analyzed in phonemic terms. However, a phoneme is generally regarded as an abstraction of a set (or equivalence class ) of speech sounds ( phones ) which are perceived as equivalent to each other in a given language.
Diphthong A diphthong ( pron.: / ˈ d ɪ f θ ɒ ŋ / or / ˈ d ɪ p θ ɒ ŋ / ; [ 1 ] Greek : δίφθογγος , diphthongos , literally "two sounds" or "two tones"), also known as a gliding vowel , refers to two adjacent vowel sounds occurring within the same syllable . Technically, a diphthong is a vowel with two different targets: that is, the tongue moves during the pronunciation of the vowel. For most dialects of English , the sentence "no highway cowboys" contains five distinct diphthongs.
Speech synthesis Stephen Hawking is one of the most famous people using speech synthesis to communicate 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. [ 1 ]
Diagram of basic procedure to determine whether two sounds are allophones In phonology , an allophone ( pron.: / ˈ æ l ə f oʊ n / ; from the Greek : ἄλλος , állos , "other" and φωνή, phōnē , "voice, sound") is one of a set of multiple possible spoken sounds (or phones ) used to pronounce a single phoneme . [ 1 ] For example, [pʰ] (as in pin ) and [p] (as in spin ) are allophones for the phoneme /p/ in the English language . Although a phoneme's allophones are all alternative pronunciations for a phoneme, the specific allophone selected in a given situation is often predictable. Allophone
