The deception detection technology based on voice signals, developed by Pravdalist.ai, has no analogs in the world. There are numerous studies in this field conducted over the past decade in different countries, and reviews of these studies can be found at the links below:
- Deception detection with machine learning: A systematic review and statistical analysis ,
- A Comprehensive Review on Features Extraction and Features Matching Techniques for Deception Detection ,
- Deception detection: State of the art and future prospects
At the end of the documents, there is a list of references to these research papers. To briefly describe their results, they failed to achieve an accuracy higher than 70%. This makes these competing developments unsuitable for industrial applications. The only solution currently in mass use is the polygraph, but it also does not provide accurate results.
