| language tests | Tests designed to assess language behaviour and abilities. They include tests of vocabulary, comprehension, grammar and functional use of language, e.g., development sentence scoring, receptive-expressive emergent language scale, parsons language sample, utah test of language development, michigan language inventory and verbal language development scale, illinois test of psycholinguistic abilities, northwestern syntax screening test, peabody picture vocabulary test, ammons full-range picture vocabulary test, and assessment of children's language comprehension.

| alaryngeal speech | A form of speech achieved after laryngectomy by using either an external vibratory source or the pharyngoesophageal segment as an internal vibratory source. Tracheoesophageal speech may be produced after laryngectomy by surgically diverting exhaled air to the pharynx by a permanently constructed tracheoesophageal fistula. (05 Mar 2000) |
| audiometry, speech | Measurement of the ability to hear speech under various conditions of intensity and noise interference using sound-field as well as earphones and bone oscillators. (12 Dec 1998) |

| motor speech centre | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
| helium speech | The peculiar high-pitched, often unintelligible speech sounds produced when one breathes a mixture of up to 80 per cent helium and 20 per cent oxygen. (05 Mar 2000) |

| scanning speech | Measured or metered, often slow speech. (05 Mar 2000) |
| sensory speech centre | The region of the cerebral cortex thought to be essential for understanding and formulating coherent, propositional speech; it encompasses a large region of the parietal and temporal lobes near the lateral sulcus of the left cerebral hemisphere; corresponding approximately to Brodmann's areas 40, 39, and 22. Synonym: sensory speech centre, Wernicke's area, Wernicke's field, Wernicke's region, Wernicke's zone. (05 Mar 2000) |
