This paper describes a new Japanese text-to-speech (TTS) system that can produce highly natural and intelligible synthetic speech. The good performance of the new TTS system derives from three new sophisticated approaches as follows; (1)A new prosody control algorithm that uses prosody data extracted from a natural speech database and a duration control algorithm based on statistical estimation...

In this paper we will discuss recent advances in multilingual text-to-speech (TTS) synthesis research at AT&T Bell Laboratories. The TTS system developed at AT&T Bell Laboratories generates synthetic speech by concatenating segments of natural speech. The architecture of the system is designed as a modular pipeline where each module handles one particular step in the process of converting text ...

Proper accentuation and phrasing make the syntactic and semantic structure of the message more transparent to the listener. Therefore a good modeling of prosody in a TTS system has to be structured into appropriate levels. The implemented prosodic hierarchy should guide the listeners’ attention and help in support of the comprehension process. Since prosody functions as a distractor, it is very...

In order to enable face animation on the Internet using high quality synthetic speech, the Text-to-Speech (TTS) servers need to be implemented on network-based servers and shared by many users. The output of a TTS server is used to animate talking heads as defined in MPEG-4. The TTS server creates two sets of data: audio data and Phonemes with optional Facial Animation Parameters (FAP) like smi...

this paper presents an evolution in the design of multi-domain unit selection text-to-speech (MD-TTS) architecture. The goal of this approach is to achieve good synthetic quality like the limited domain TTS systems, without discarding a general purpose synthesis. The multi-domain architecture entails a speech corpus containing several domains. Moreover, it has been hierarchically structured by ...

This paper deals with a speech synthesis. Speech synthesis is an artificial production of speech by a computer. Speech synthesis from a text is called Text-to-Speech (TTS) synthesis. The main goal of this paper is to propose and implement a TTS system based on the MBROLA (Multiband Resynthesis Overlap-Add) project. We implement jSynt tool, a TTS system written in java. The first version include...

This paper proposes a method for formal real-time systems development: Requirements and high level design decisions are time interval properties and are therefore specified in the Duration Calculus (DC), while implementations are described by timed transition systems (TTS). A link from implementation properties to the requirement and design properties is given by interpreting a DC formula in a ...

Text-to speech (TTS) systems which mainly meant for speech synthesis are, used for one of the South Indian languages called Malayalam. The paper makes a brief study on, Malayalam linguistics, and also gives a comparison between two prominent methodologies for speech synthesis, viz Concatenative based synthesis and HMM based synthesis. As a result, the paper mentions some of the problems facing ...

The paper presents the Loquendo TTS approach to mixedlanguage speech synthesis, offering a range of options to face the various situations where texts may occur in different languages or embedding foreign phrases. The most challenging target is to make a monolingual TTS voice read a foreign language text. The adopted Foreign Pronunciation Strategy here discussed allows mixing phonetic transcrip...
