The synthesis of an artificial language can provide some interesting extensions for the evaluation of text-to-speech (TTS) systems. For the alternative evaluation of the TTS system DRESS a new module for the artificial language Klingon has been developed. The linguistic and phonetic structure of Klingon can be modeled mainly by rules, with less exceptions. This contribution introduces the multi...

The paper presents platform for web based TTS modules and systems evaluation named RES (Remote Evaluation System). It is being developed within the European Centre of Excellence for Speech Synthesis (ECESS, www.ecess.eu). The presented platform will be used for web based online evaluation of various text-to-speech (TTS) modules, and even complete TTS systems, presently running at different Inst...

A Frisian adaptation of a Dutch TTS system based on Festival, NeXTeNS, is presented as a case study in prototyping TTS for resource-poor minority languages. For these languages, demonstrator systems are essential to seed projects in speech and language technology. The conversion of a Dutch TTS system to a new language with minimal speech and language resources, Frisian, demonstrates that a TTS ...

A detailed discussion of the X-ray luminosity functions of pre-main sequence and young main-sequence objects in the Taurus-AurigaPerseus region based on the ROSAT archive is presented. One of the main conclusions is that the XLF of classical and weak-line T Tauri stars (TTS) are different: weak-line TTS are X-ray brighter than classical TTS. Various possible biases related to the sample selecti...

The objective of the Hughes Trainable Text Skimmer (TTS) Project is to create text skimming softwar e that: (1) can be easily re-configured for new applications, (2) improves its performance with use, and (3) is fas t enough to process several megabytes of text per day. The TTS-MUC4 system is our second full-scale prototype . I t is an adaptation of the TTS-MUC3 system [1] [2], which constitute...

The paper gives a retrospective of the development of speech synthesis systems, from mechanical synthesisers to computer systems for text-to-speech conversion (TTS) and analyses the perspectives of biomechanical and multimodal TTS systems within dialogue systems addressing higher cognitive levels as well. Special attention is given to the methods for assessment of the quality of synthesised spe...

A restricted domain text-to-speech system oriented to a weather forecast application is presented. This TTS system is embedded in a multimedia interactive service accessible from different media, such as TV, Internet and mobile devices. The requirements of this application give rise to several particularities in the design and implementation of the TTS system, which are discussed throughout thi...

In this paper we discuss the implementation of an Afrikaans TTS system that is based on diphones. Using diphones makes the system flexible but presents other challenges. A previous effort to design an Afrikaans TTS system was done by SUN. They implemented a TTS system based on full words. A full word based TTS system produces more natural sounding speech than when the system is designed using o...

Indoleamine-2,3-dioxygenase (IDO) and tryptophanyl-tRNA-synthetase (TTS) are interferon-gamma (IFN-gamma)-inducible enzymes that are responsible for tryptophan degradation and for its use in protein synthesis, respectively. IFN-gamma-induced IDO has immunomodulatory properties in murine and human models. A concomitant increase of TTS has been postulated to protect the IDO-expressing cells from ...

HMM-based parametric speech synthesis has recently become an alternative to the concatenative TTS approach, especially when low footprint and general speech domain are required. A majority of speech parameterization models used in state-ofthe art HMM TTS systems employ source-filter waveform synthesis schemes. Sinusoidal representation and waveform generation of speech is an alternative to the ...
