The speech recognition software we use is “speaker dependent” and requires the type of training described here: “Some SR systems use ‘training’ (also called ‘enrollment’) where an individual speaker reads text or isolated vocabulary into the system. The system analyzes the person’s specific voice and uses it to fine-tune the recognition of that person’s speech, resulting in increased accuracy. Systems that do not use training are called ‘speaker independent’ systems” (see video 3.4.1) (Wikipedia 16 February 2017).
