  2. Polytropic process - Wikipedia

    en.wikipedia.org/wiki/Polytropic_process

    A polytropic process is a thermodynamic process that obeys the relation: = where p is the pressure , V is volume , n is the polytropic index , and C is a constant. The polytropic process equation describes expansion and compression processes which include heat transfer.

  3. Syncope (phonology) - Wikipedia

    en.wikipedia.org/wiki/Syncope_(phonology)

    In phonology, syncope (/ ˈ s ɪ ŋ k ə p i /; from Ancient Greek: συγκοπή, romanized: sunkopḗ, lit. 'cutting up') is the loss of one or more sounds from the interior of a word, especially the loss of an unstressed vowel.

  4. Isentropic process - Wikipedia

    en.wikipedia.org/wiki/Isentropic_process

    A process during which the entropy remains constant is called an isentropic process, written = or =. [12] Some examples of theoretically isentropic thermodynamic devices are pumps, gas compressors, turbines, nozzles, and diffusers.

  5. Speech perception - Wikipedia

    en.wikipedia.org/wiki/Speech_perception

    Speech agnosia: Pure word deafness, or speech agnosia, is an impairment in which a person maintains the ability to hear, produce speech, and even read speech, yet they are unable to understand or properly perceive speech. These patients seem to have all of the skills necessary in order to properly process speech, yet they appear to have no ...

  6. Phonological change - Wikipedia

    en.wikipedia.org/wiki/Phonological_change

    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]

  7. Spatial hearing loss - Wikipedia

    en.wikipedia.org/wiki/Spatial_hearing_loss

    This is the interaural time difference (ITD) cue and is measured by signal processing in the two central auditory pathways that begin after the cochlea and pass through the brainstem and mid-brain. [3] Some of those with spatial hearing loss are unable to process ITD (low frequency) cues.

    See buccal speech. [1] after a laryngectomy, the esophagus may be used (notated {Œ} for simple esophageal speech, {Ю} for tracheo-esophageal speech in VoQS, and notated {И} for electrolaryngeal speech). See esophageal speech. [2] the pharynx, and replacing the glottis using the tongue and the upper alveolus, the palate, or the pharyngeal wall.

  9. Speech and language impairment - Wikipedia

    en.wikipedia.org/wiki/Speech_and_language_impairment

    Speech-language pathologists create plans that cater to the individual needs of the patient. If speech is not practical for a patient, the SLP will work with the patient to decide upon an augmentative and alternative communication (AAC) method or device to facilitate communication. They may work with other patients to help them make sounds ...
