As Technology progress deeper into submicron CMOS, traditional analog circuits face problems that are not to be solved purely by analog innovations. Instead, new architectures are being proposed which take advantages of the relatively cheaper of the digital circuits to augment or improve the diminishing performance of the analog circuitry. The conventional approach performs the design of 14 ban...

This paper analyses substrate-related spurious tones in fractional-N phaselocked loops with integrated VCOs. Spur positions are calculated and experimentally verified as a function of the divider ratios of prescaler and programmable divider. For an integrated wideband PLL in SiGe BiCMOS technology the spur power levels are measured and compared with theoretical expectations. The power in these ...

Vowelization presents a principle difficulty in building text-tospeech synthesizers for speech-to-speech translation systems. In this paper, a novel log-linear modeling method is proposed that takes into account vowel and diacritical information at both the word level and character level. A unique syllable based normalization algorithm is then introduced to enhance both word coverage and data c...

INTRODUCTION The present paper is divided into three parts: a. the synthesiser, b. control of the synthesiser and c. use of synthesizers. There is no attempt to give a detailed account of the history of speech synthesis (for this, see: Flanagan, 1965 and Mattingly, 1968), nor any account of the details of computer programming for the control of synthesizers: what this paper is mainly concerned ...

This paper describes the AEON system whose aim is to synthesize scheduling algorithms from high-level models. AEON, which is entirely written in COMET, receives as input a high-level model for a scheduling application which is then analyzed to generate a dedicated scheduling algorithm exploiting the structure of the model. AEON provides a variety of synthesizers for generating complete or heuri...

In this paper we describe the role of multilingual models in the creation and deployment of unit selection based bilingual speech synthesizers. We first review the definition of a multilingual phonetic alphabet for the simultaneous recognition of up to fifteen languages, and then discuss synthesis specific modifications that allow a more detailed description of the synthesizers’ unit inventorie...

Analog synthesizers continue to be used by many musicians because of their distinctive timbres, intuitive real-time control and flexible patching. There has been recent interest in simulating the analog signal chain with digital techniques. However, a literal time-domain translation of analog VCOs and VCFs is surprisingly challenging. This paper presents a new strategy for digital simulation ba...

This study examined word level intelligibility differences between DECTalk and MacinTalk speech synthesizers using the Modified Rhyme Test in an open format transcription task. Three groups of listeners participated: inexperienced, speech-language pathologists, and speech synthesis experts. Results for between-subjects ANOVA showed that the expert group correctly identified a significantly high...
