Perceptual Quality Dimensions of Text-to-Speech Systems
نویسندگان
چکیده
The aim of this paper is to analyze the perceptual quality dimensions of state-of-the-art text-to-speech systems (TTS). Therefore, several pretests were conducted to determine a suitable set of attribute scales. The resulting 16 scales were used in a semantic differential on a diverse database containing 16 different TTS systems. A subsequent multidimensional analysis (Principal Axis Factor analysis with Promax rotation) resulted in three underlying quality dimensions. They were labeled naturalness, disturbances, and temporal distortions. A mapping of these factors onto the perceived overall quality revealed that naturalness contributes the most to the quality of TTS signals.

This study was intended first to categorize the L2 learners in terms of their learning style preferences and second to investigate if their learning preferences are related to lexical inferencing. Moreover, strategies used for lexical inferencing and text related issues of text density and parts of speech were studied to determine their moderating effects and the best predictors of lexical infe...
متن کاملPerceptual speech quality dimensions in a conversational situation
Speech telecommunication systems are most frequently used in conversational situations. In this regard, assessing the quality of conversational speech is the fundamental requirement for system developers to classify and evaluate their systems. However, it is not enough to provide information about the overall quality, but also to point out sources for possible quality-losses. We present a follo...

Abstract Speech databases are part of the concatenative text to speech synthesis systems. Phonetic quality of the databases plays a significant role in the naturalness of the synthesized speech. This paper introduces two syllable and diphone speech databases for Persian and investigates the way of their development and their specifications and their advantages to each other. ...

In this paper, we present a comparative overview of 9 studies on perceptual quality dimensions of synthetic speech. Different subjective assessment techniques have been used to evaluate the text-to-speech (TTS) stimuli in each of these tests: in a semantic differential, the test participants rate every stimulus on a given set of rating scales, while in a paired comparison test, the subjects rat...
