OBJECTIVE To develop a technological tool that improves the initial learning of sign language in hearing impaired children. METHODS The development of this research was conducted in three phases: the lifting of requirements, design and development of the proposed device, and validation and evaluation device. Through the use of information technology and with the advice of special education pr...

This paper describes a singing-to-speaking synthesis system called “SpeakBySinging” that can synthesize a speaking voice from an input singing voice and the song lyrics. The system controls three acoustic features that determine the difference between speaking and singing voices: the fundamental frequency (F0), phoneme duration, and power (volume). By changing these features of a singing voice,...

Until now little research has been done in the area of animal sound identification. Animal sound classification and retrieval is very helpful for bioacoustics and audio retrieval applications. This paper is a literature review of an animal identification and detection system based on animal voice pattern recognition. The system uses the ZeroCross-Rate (ZCR), Mel-Frequency Cepstral Coefficients ...

Intelligent personal assistants (IPAs), also known as smart speakers, are becoming part of everyday life in more and households around the world. Phone household IPAs integrated intimate home contexts require connections to (social) media profiles, user accounts, domestic appliances. Users can control their with voice-activated commands order make convenient efficient. Yet, bring privacy survei...

This paper addresses the challenging scenario for the distanttalking control of a music playback device, a common portable speaker with four small loudspeakers in close proximity to one microphone. The user controls the device through voice, where the speech-to-music ratio can be as low as −30 dB during music playback. We propose a speech enhancement front-end that relies on known robust method...

Voice based human–computer interactions have raised much interest and found various applications. Some extant voice based interactions only support voice commands with fixed vocabularies or preset expressions. This paper is motivated to investigate an approach to implement a flexible voice-enabled CAD system, where users are no longer constrained by predefined commands. Designers can, to a much...
