| Tourette's syndrome is an inherited neurobehavioural disorder characterised by sudden, involuntary, repetitive muscle movements and vocalisations. |
| Most house sparrow vocalisations are variations on its short and incessant chirping call. |
| They thus learn to socialise and, frequently through vocalisations, discover what may be dangerous or beneficial for them. |
| An accordion plays like a portative organ continuo, hocket-ing wind instruments evoke period vocalisations, and contrasts of effect bring continual surprises. |
| But these vocalisations should not be elevated to the status of human communications. |
| Your horse learns words, phrases, body language and vocalisations so that it can understand you and guess what you're going to do next. |
