Text analysis for speech synthesis is described in relation to the information needed in speech production. This includes a pronouncing dictionary and letter-to-sound rules, morphological analysis and accent assignment, and syntactic analysis. Prosody control rules (fundamental frequency control and segmental duration control) are examined. Speech units for synthesis and parametric representation of speech signals are discussed. Applications and development tools are considered 相似文献

A novel system which employs the filter bank analysis and synthesis method for the packetisation of speech is proposed. Preliminary computer simulation studies of the system and informal subjective listening tests indicate that significant improvement in the recovered speech can be obtained, compared with the conventional technique of straight packetisation of PCM speech.<> 相似文献

Research in human/computer interaction has mainly focused on natural language, text, speech and vision primarily in isolation. Recently there have been a number of research projects that have concentrated on the integration of such modalities using intelligent reasoners. The rationale is that many inherent ambiguities in single modes of communication can be resolved if extra information is available.This paper describes an intelligent multi-modal system called the Smart Work Manager. The main characteristics of the Smart Work Manager are that it can process speech, text, face images, gaze information and simulated gestures using the mouse as input modalities, and its output is in the form of speech, text or graphics. The main components of the system are the reasoner, a speech system, a vision system, an integration platform and the application interface. The overall architecture of the system will be described together with the integration platform and the components of the system which include a non-intrusive neural network based gaze-tracking system. The paper concludes with a discussion on the applicability of such systems to intelligent human/computer interaction and lessons learnt in terms of reliability and efficiency. 相似文献

A text to speech synthesis system receives as its input textual information and produces a speech signal as an output message. In the area of multimodal interfaces, problems concerning assistive communication for handicapped people requires implementation of various technologies using the “text to speech synthesis” block. This use of vocal synthesis is aimed at users with visual deficiencies or with cerebral palsy. In this article we describe the major technical advancse producing speech from text. 相似文献

Humans find speech a convenient and efficient means for communicating infonnation. Machines, in contrast, prefer the symbols of assemblers and compilers-exchanged, typically, in printed form through a computer terminal. If computers could be given human-like abilities for voice communication, their value and ease of use for humans would increase. The ubiquitous telephone would take on more of the capabilities of a computer terminal. Making machines talk and listen to humans depends upon economical implementation of speech synthesis and speech recognition. Heretofore the complexities and costs of these functions have deterred wide application. But now, fueled by the advances in integrated electronics, opportunities for expanded and enhanced telephone services are emerging. This paper assesses the progress in synthesis and recognition of speech by computer techniques, and it outlines potential applications in voice-communication services. 相似文献
