Revealing the most Significant Deterioration Factors in Single Candidate Synthetic Speech
نویسندگان
چکیده
The paper focuses on revealing the factors that cause the deterioration of the naturalness of synthetic speech. Modified listening tests are used for this task, as we also need to determine the impact of each considered factor. Synthetic speech generated by the single candidate version of our TTS was examined with the use of modified listening tests, and the most prominent deterioration factors were evaluated on two corpora. The most significant factor turned out to be the extensive modification of units, followed by segmentation inaccuracy and spectral discontinuities. However, the last two were not so significant. Listening tests described in this paper can be used not only for testing single candidate TTS systems, but also for testing other types of TTS. In fact, what is required to test depends only on the definition of the set of factors.

متن کاملQuality Deterioration Factors in Unit Selection Speech Synthesis
The purpose of the present paper is to examine the relationships between target and concatenation costs and the quality (with focus on naturalness) of generated speech. Several synthetic phrases were examined by listeners with the aim to find unnatural artefacts in them, and the mutual relation between the artefacts and the behaviour of features used in given unit selection algorithm was examined.

Our reasearch goal is to construct a Japanese TTS (Text-to-Speech) system that can output various kinds of prosody. Since such synthetic speech is useful for a practical use, many TTS systems have implemented global prosodic control processing. But fundamentally they're designed to output speech with standard pitch and speech rate. We discuss synthesis method for high quality speech with extrem...
