STKU-2: The Nuts & Bolts of Tuning a Speech Application

SpeechTEK University – Sunday 23 April 
13:30 – 16:30

The workshop provides step-by step guidelines of the speech application tuning process, starting with data collection, data transcriptions, and data tagging and going all the way to delivering a customer-focused recommendation report. Participants gain firsthand understanding of the three aspects of tuning: speech recognition performance, grammar, and dialogue design. The course examines whole call recording tools as well as tools that capture speech event logs and produces metrics. Participants engage in a structured tuning data analysis that targets high-usage dialogue states. In addition to traditional methods, the course introduces an innovative approach to tuning by combining a heuristic usability evaluation with the analysis. This simple, low-cost, low-impact usability assessment provides a caller focus and translates directly to building a business case for the tuning recommendations. Finally, the course explores how tuning methods need to adapt to the broader speech landscape that now includes multi-channel applications, in-car applications, wearables, and mobile devices.
