| transmission threshold | <epidemiology> Occurs for a parasite when the basic reproductive rate Ro is equal to 1. Below this threshold level the disease is unable to maintain itself within the host population. Typically, for directly transmitted parasites there is a transmission threshold for the host population size. (05 Dec 1998) |

| 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) |
