Abstract

The SpeechAuth research project aims, mainly, to discover a new and efficient technique for biometric authentication and digital speech recognition, based on voice analysis, to be used in real-time. The new technique will run in a DSP - Digital Signal Processor, generating a robust system with a wide range of real applications in respect to gate control, restrict electronic data, command interpretation in cars, computers, electronic devices, among several others.
