Advances on the Transcription of Historical Manuscripts based on Multimodality, Interactivity and Crowdsourcing

The transcription of digitalised documents is useful to ease the digital access to their contents. Natural language technologies, such as Automatic Speech Recognition (ASR) for speech audio signals and Handwritten Text Recognition (HTR) for text images, have become common tools for assisting transcribers, by providing a draft transcription from the digital document that they may amend. This draft is useful when it presents an error rate low enough to make the amending process more comfortable than a complete transcription from scratch. The work described in this thesis is focused on the improvement of the transcription offered by an HTR system from three scenarios: multimodality, interactivity and crowdsourcing. The image transcription can be obtained by dictating their textual contents to an ASR system. Besides, when both sources of information (image and speech) are available, a multimodal combination is possible, and this can be used to provide assistive systems with additional sources of information. Moreover, speech dictation can be used in a multimodal crowdsourcing platform, where collaborators may provide their speech by using mobile devices. Different solutions for each scenario were tested on two Spanish historical manuscripts, obtaining statistically significant improvements
