9. An apparatus comprising: at least one processor; and at least one storage medium having encoded thereon processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to carry out a method of processing results of a recognition by an automatic speech recognition (ASR) system on a speech input, the results comprising a first recognition result identified by the ASR system as most likely to be a correct recognition result for the speech input, the results further comprising at least one alternative recognition result identified by the ASR system, the method comprising: determining whether a meaning of the first recognition result differs in a medically significant way from a meaning of the at least one alternative recognition result; and in response to determining that that the meaning of the first recognition result differs in a medically significant way from the meaning of the at least one alternative recognition result, triggering an alert.

The apparatus of claim 9 , wherein the determining whether the meaning of the first recognition result differs in a medically significant way from the meaning of the at least one alternative recognition result comprises determining whether the first recognition result includes a first member of a set of words or phrases, each member of the set comprising a word or phrase and being associated with at least one other member of the set, and determining whether the at least one alternative recognition result includes at least one other member associated with the first member of the set.
