Webspeciﬁc challenges of far-ﬁeld ASR and how they are approached. We will discuss the general components of an ASR system only as much as is necessary to understand the modiﬁcations introduced in the far-ﬁeld scenario. The organization of the paper is oriented along the processing pipeline of a typical far-ﬁeld ASR as shown in Fig. 1. WebIn this paper we detail a data augmentation approach for far-field ASR. We examine the impact of using simulated room impulse responses (RIRs), as real RIRs can be difficult to acquire, and also the effect of adding point-source noises. paintball shops in calgary
