5:00pm to 5:20pm
I did an introduction to voice recognition / speech recognition and went on to differentiate between:
a) speaker-independent speech recognition as you find it in automated Call Centres (IVRs that ask you to press buttons or speak your choice)
b) speaker-independent speech recognition as you find it on your smartphone.
Call Centre apps have got limited vocabularies but recognition is quite good if you stay on the topic (and don't go on a tangent on the ills of Consumerism or something!).
Smartphone apps have got huge vocabularies that cover the most common words in a language, but don't work very well because recognition is not context-dependent. You may indeed be talking about the ills of Consumerism or sending your beloved a kiss.
A live test among the participants of this sessions showed that "Salford" cannot and will not ever be recognised - alas!
