Impact of Phonetic Annotation Precision on Automatic Speech Recognition Systems
Original language description
In this paper we study the impact of phonetic annotation precision on the accuracy of a state-of-the art ASR (automatic speech recognition) system. This issue becomes important especially if we want to port the system to a new language without spending much time by collecting, checking and annotating a large amount of acoustic data in the target language. First, we describe a series of experiments that demonstrate how inaccurate annotation influences word error rate of a gaussian-mixture model and deep-neural net based ASR. Our results show that even significantly inaccurate annotations allow to achieve fairly good results. On the other side, if we want to get really good performance, we should assure that the annotations are as precise as possible. Therefore, we describe methods that can do most of the annotation work in an almost automatic (iterative) way with a high precision. We demonstrate them on an ASR system that is being adapted from Czech language to Polish. We provide results achieved on Polish GlobalPhone and Clarin speech databases.
