Have you ever wanted to compare automatic speech recognition (ASR) engines? That was the topic of a three-hour tutorial given by Voxeo’s Dan Burnett at SpeechTEK last week in New York. Dan gave a hands-on session as part of “SpeechTEK University” where students received an in-depth lesson in how to compare and evaluate ASR engines. The session description was:
9:00 AM – 12:00 PM – STKU4 – Performing a Comparative ASR Evaluation- Dan Burnett, Director of Speech Technologies
There are a variety of choices for speech recognition engines, especially for languages other than English. Although many companies are comfortable performing business case analysis across speech recognition engine vendors, it is often difficult to know how to compare accuracy. In this handson, in-depth course you will learn how to select an appropriate evaluation data set, why transcription is important and how to do it properly, how to perform the evaluation, and how to analyze and interpret the results.
Dan’s slides are available for viewing and download:
Obviously you need some of the sample files to work through the lab exercises, but the rest of slides do cover what Dan discussed.
