چکیده
An automatic method to create CV forrnantsource templates from continuous speech corpus is proposedfor speechsynthesis,where the boundaries of the CV templates are decided on the basis of the Mahalanobis distance. The synthetic experiments have proved the methodto be useful.

Syllable Specific Unit Selection Cost Function Using a Tone Modeling Technique for Automatic Phonetic Segmentation of Hindi Speech Using HMM
This paper presents a technique of improving tone correctness in speech synthesis of a tonal language based on an average-voice model trained with a corpus from nonprofessional speakers speech. Unit selection-based concatenative synthesis is one of the widely used speech synthesis approaches. This approach overcomes the limitations of other synthesis techniques such as articulatory synthesis an...
متن کاملDecision Tree Classification Approach for Model Selection in Segmenting Mandarin TTS Corpus
High accuracy automatic segmentation of Mandarin TTS (text to speech) corpus is vital for obtaining high quality syllable’s boundary to corpusbased speech synthesis. Among the existing methods, most studies on automatic segmentation are based upon single model, ignoring the diverse time marks gained by different models in specific Mandarin boundary environment. In this paper, three hidden Marko...
متن کاملA hybrid approach to segmentation of speech using group delay processing and HMM based embedded reestimation
The most popular method for automatic segmentation is embedded reestimation of monophone HMMs after flat start initialization, followed by forced alignment. This method may not yield accurate boundaries. To address this issue, group delay based processing of short-time energy (STE) is performed on the speech signal to obtain syllable boundaries. The syllable boundaries are accurate, but there a...
متن کاملWord segmentation in Persian continuous speech using F0 contour
Word segmentation in continuous speech is a complex cognitive process. Previous research on spoken word segmentation has revealed that in fixed-stress languages, listeners use acoustic cues to stress to de-segment speech into words. It has been further assumed that stress in non-final or non-initial position hinders the demarcative function of this prosodic factor. In Persian, stress is retract...

This paper presents an automatic speech segmentation method based on HMM alignment and a categorized multiple-expert fine adjustment. The accuracy of syllable boundaries is significantly improved (72.8% and 51.9% for starting and ending boundaries of syllables, respectively) after the fine adjustment. Moreover, a novel phonetic verification method for checking inconsistency between text script ...
