Speech Synthesis for a Speci c Speaker Based on a Labeled Speech Database
نویسندگان
چکیده
This paper proposes a new text-to-speech synthesis technique, for producing continuous, natural sounding speech of a speci c speaker. The synthesis technique is based on selecting short speech frames from a phoneme-labeled speech database. The selection procedure involves minimization of a distortion criterion, by a dynamic programming algorithm. The proposed scheme is more exible than many existing schemes using xed speech segments, such as diphones. It results in a more natural synthesized speech. An e cient speech representation is used to express simply and accurately the spectral continuity of speech. A further improvement in the database search mechanism and in database size was obtained by sectioning the speech phonemes into \steady-states" and \transitions". The resulting synthesized speech quality, is satisfactory and indeed preserves the natural voice of the speaker.

A Comparative Study of Gender and Age Classification in Speech Signals
Accurate gender classification is useful in speech and speaker recognition as well as speech emotion classification, because a better performance has been reported when separate acoustic models are employed for males and females. Gender classification is also apparent in face recognition, video summarization, human-robot interaction, etc. Although gender classification is rather mature in a...
متن کاملRecognizing the Emotional State Changes in Human Utterance by a Learning Statistical Method based on Gaussian Mixture Model
Speech is one of the most opulent and instant methods to express emotional characteristics of human beings, which conveys the cognitive and semantic concepts among humans. In this study, a statistical-based method for emotional recognition of speech signals is proposed, and a learning approach is introduced, which is based on the statistical model to classify internal feelings of the utterance....
متن کاملSpeaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation
A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...
