Abstract
The theories and applications of speaker identification, recognition, and verification are among the well-established fields. Many publications and advances in the relevant products are still emerging. In this paper, research-related publications of the past 25 years (from 1996 to 2020) were studied and analysed. Our main focus was on speaker identification, speaker recognition, and speaker verification. The study was carried out using the Science Direct databases. Several references, such as review articles, research articles, encyclopaedia, book chapters, conference abstracts, and others, were categorized and investigated. Summary of these kinds of literature is presented in this paper, together with statistical analyses to represent the publications and their categories over the mentioned period. Important information, including the dataset used, the size of the data adopted, the implemented methods, and the accuracy of the obtained results in the analysed research, are extracted from the explored publications and tabulated. The results show that the sum of published research articles is outnumbering other categories of publications. The number of researches in speech and speaker identification, recognition, and verification shows an increasing trend. Based on the normalized comparative factors of research publications, we found that many of them reached a high level of accuracy in their findings; hence the significantly superior techniques were derived and discussed for future researches. This survey paper would be beneficial for all those who wish to enhance their researches in the area of voice identification, recognition, and verification.
Highlights
The secrecy and protection of information of every organization is utmost important for sustainability and continuous development purposes
Three interrelated scientific fields were considered in the critical review that is presented in this paper
Speaker recognition, and speaker verification are the research areas that are adopted, where a systematic analysis for the methods and techniques used in the establishment of their theoretical basis and applicability was conducted
Summary
The secrecy and protection of information of every organization is utmost important for sustainability and continuous development purposes. The biometric characteristics are distinct from one to other human being. They can be broadly divided up into physiological characteristics and may include fingerprint recognition, face recognition, ear form, DNA, and behavioural characteristics. Biometric characteristics may include speaker recognition, signature recognition, voice pattern, and gait recognition. They can be obtained and measured from a biometric sample for the purpose of biometric identification. A general speaker identification system is basically composed of two phases; training phase, and testing phase.
