Kurzfassung:
To address the challenges surrounding data quantity and quality in Intelligent Speech Analysis, this thesis proposes and analyses semi-autonomous data enrichment and optimisation approaches. Particularly, both labelled and unlabelled data from heterogeneous resources are exploited; Split Vector Quantisation is employed for feature compression; and Long Short-Term Memory recurrent neural networks is evaluated to mitigate reverberation. With these approaches, better performance is delivered.
