Investigation of emotionally morphed speech perception and its structure using a high quality speech manipulation system
نویسندگان
چکیده
A series of perceptual experiments using morphed emotional speech sounds was conducted. A high-quality speech modification procedure STRAIGHT [1] extended to enable auditory morphing[2] was used for providing CD quality test stimuli. The test results indicated that naturalness of morphed speech samples were comparable to natural speech samples and resynthesized samples without any modifications when interpolated. It also indicated that the proposed morphing procedure enables to provide stimulus continuum between different emotional expressions. Partial morphing tests were also conducted to evaluate relative contributions and interdependence between spectral, temporal and source parameters.

Persian Phone Recognition Using Acoustic Landmarks and Neural Network-based variability compensation methods
Speech recognition is a subfield of artificial intelligence that develops technologies to convert speech utterance into transcription. So far, various methods such as hidden Markov models and artificial neural networks have been used to develop speech recognition systems. In most of these systems, the speech signal frames are processed uniformly, while the information is not evenly distributed ...
متن کاملStudy on manipulation method of voice quality based on the vocal tract area function
This paper describes a new manipulation method of voice quality which is based on the STRAIGHT analysis-synthesis system. This method manipulates voice quality by changing the vocal tract area function calculated from the PARCOR coefficients. The PARCOR coefficients used in the proposed method is obtained from the auto-correlation function of the STRAIGHT spectrum. We have implemented a simple ...

Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...

Speech Emotion Recognition (SER) is an important part of speech-based Human-Computer Interface (HCI) applications. Previous SER methods rely on the extraction of features and training an appropriate classifier. However, most of those features can be affected by emotionally irrelevant factors such as gender, speaking styles and environment. Here, an SER method has been proposed based on a concat...
