Abstract

With the advancement of speech recognition technologies, there is an increase in the adoption of voice interfaces on mobile-based platforms. While, developing a general purpose Automatic Speech Recognition (ASR) which can understand voice commands is important, the contexts of how people interact with their mobile device change very rapidly. Due to the high processing complexity of the ASR engine, much of the processing of trending data is being carried out on cloud platforms. Changed content regarding news, music, movies and TV series change the focus of interaction with voice based interfaces. Hence ASR engines trained on a static vocabulary may not be able to adapt to the changing contexts. The focus of this paper is to first describe the problems faced in incorporating dynamically changing vocabulary and contexts into an ASR engine. We then propose a novel solution which shows a relative improvement of 38 percent utterance accuracy on newly added content without compromising on the overall accuracy and stability of the system.
