In historical linguistics, a sound change is a change in the pronunciation of a language. A sound change can involve the replacement of one speech sound (or, more generally, one phonetic feature value) by a different one (called phonetic change) or a more general change to the speech sounds that exist (phonological change), such as the merger of two sounds or the creation of a new sound.
Sound change may be an impetus for changes in the phonological structures of a language (and likewise, phonological change may sway the process of sound change). [1] One process of phonological change is rephonemicization, in which the distribution of phonemes changes by either addition of new phonemes or a reorganization of existing phonemes. [2]
Replacing a sound by another allophone of the same phoneme usually does not change the meaning of a word, but the result may sound non-native or even unintelligible. Native speakers of a given language perceive one phoneme in the language as a single distinctive sound and are "both unaware of and even shocked by" the allophone variations that ...
The sound that /t/ and /d/ (in this example) change to, or the individual features that change. The slash is a shorthand notation for "in the environment where...". [5] It means that the notation to the right describes where the phonological rule is applied. The sound, or the features of the sound, that precedes the one to be changed.
The sound change of palatalization sometimes involves lenition. Lenition includes the loss of a feature, such as deglottalization, in which glottalization or ejective articulation is lost: [kʼ] or [kˀ] > [k]. The tables below show common sound changes involved in lenition. In some cases, lenition may skip one of the sound changes.
Sound change—i.e., change in the pronunciation of phonemes—can lead to phonological change (i.e., change in the relationships between phonemes within the structure of a language). For instance, if the pronunciation of one phoneme changes to become identical to that of another phoneme, the two original phonemes can merge into a single ...
In signal processing, distortion is the alteration of the original shape (or other characteristic) of a signal.In communications and electronics it means the alteration of the waveform of an information-bearing signal, such as an audio signal representing sound or a video signal representing images, in an electronic device or communication channel.
In linguistics, umlaut (from German "sound alternation") is a sound change in which a vowel is pronounced more like a following vowel or semivowel. [1]The term umlaut was originally coined by Jacob Grimm in connection with the study of Germanic languages, as umlaut had occurred prominently in many of their linguistic histories (see Germanic umlaut).
