Abstract
This research investigates the creation of an audio-based character recognition system
that is able to segment, process and recognise uppercase English letters continuously
drawn by the user on a given writing surface such as a table-top using a generic writing
implement. The aim is to make use of the microphones on a single smartphone to
capture the acoustic signal generated by the user as they draw letters on the writing
surface, followed by the application of audio segmentation to subdivide the audio signal
into segments corresponding to each letter, and finally the application of a combination
of the Mel-Frequency Cepstral Coefficients feature descriptor and Support Vector Machines
to recognise the segmented letters.
