Evaluation of the voice quality and QoS in real calls using different voice over IP codecs
(Institute of Electrical and Electronics Engineers Inc., 2018)
To have an excellent voice quality in VoIP networks implies to generate studies based on the perception of the user and on the QoS analysis in the calls. In this research, it was carried out the assessment of the voice ...
Forensic speaker verification using ordinary least squares
(2019-10-02)
In Brazil, the recognition of speakers for forensic purposes still relies on a subjectivity-based decision-making process through a results analysis of untrustworthy techniques. Owing to the lack of a voice database, speaker ...
Fitting assistive technology for people with hearing loss: The importance of remote microphone systems′ electroacoustic verification
(2021-12-01)
The remote microphone system (RMS) must be appropriately working when fitting it in a person with hearing loss. For this verification process, the concept of transparency is adopted. If it is not transparent, the hearing ...
Knowledge-Based Wavelet Filters Prominently Detect Spoofed Speech
(2021-01-01)
Although voice biometrics has been at the forefront of speech technologies, spoofing attacks have been one of the main issues responsible for avoiding its practical usage in commercial applications. Consequently, this ...
