摘要

This paper explores how different synthetic speech systems can be understood in a noisy environment that resembles radio noise. This work is motivated by a need for intelligible speech in noisy environments such as emergency response and disaster notification. We discuss prior work done on listening tasks as well as speech in noise. We analyze three different speech synthesizers in three different noise settings. We measure quantitatively the intelligibility of each synthesizer in each noise setting based on human performance on a listening task. Finally, treating the synthesizer and its generated audio as a black box, we present how word level and sentence level input choices can lead to increased or decreased listener error rates for synthesized speech.
