speaker verification is the process of accepting or rejecting claimed identity in terms of its sound features. a speaker verification system can be used for numerous security systems, including bank account accessing, getting to security points, criminology and etc. when a speaker verification system wants to check the identity of individuals remotely, it confronts problems such as noise effect...

Speech is the important mode of communication and is the current research topic. The concentration is mostly focused on synthesis and analyzing part.Apart of synthesizing, text to speech system is developed.Speech synthesis is an artificial production of human speech.A text to speech system (TTS) is to convert an arbitrary text into speech.In India different languages have been spoken each bein...

In this paper, we present a new approach for the speech synthesis, in which speech utterances are synthesized using the parameters of spectro-modeling function (Multiple function). With this approach, only harmonic-parts are extracted from the phoneme spectrum, and the time-varying spectrum corresponding to the harmonics or sinusoidal components is modeled using the Multiple function. We introd...

This paper describes simple designing methods of corpus-based visual speech synthesis. Our approach needs only a synchronous real image and speech database. Visual speech is synthesized by concatenating real image segments and speech segments selected from the database. In order to automatically perform all processes, e.g. feature extraction, segment selection and segment concatenation, we simp...

This study investigated the use of pitch in pet-directed speech (PDS) when the size of the pet differs. Two Cantonesespeaking owners were recruited to talk with three dogs with different sizes. Results demonstrated that pitch level and dog size were inversely related, i.e., a higher pitch was used with a smaller dog, and vice versa. Other factors may also influence the pitch level of PDS, like ...

In this paper, we discuss a methodology for automatic prosodic modeling in Text-to-Speech (TTS) systems. The proposed methodology can be seen as a data-driven strategy to train prosodic rules from the automatic analysis of a specific text and its related speech material. Therefore, our corpus-based training procedure is based on an automatic linguistic analysis of the text and on an acoustic an...

Interlocutors are known to mutually adapt during conversation. Recent studies have questioned the adaptation of phonological representations and kinematics of phonetic variables such as loudness, speech rate or fundamental frequency. Results are often contradictory and the effectiveness of phonetic convergence during conversation is still an open issue. This paper describes an original experime...
