Speech emotion recognition has an increasingly significant role in human — computer interfaces as well as in the communication among human beings. This paper presents the results of investigations in emotion recognition based on the prosodic features of 1050 segmental and 1400 supra segmental speech wave files in English. The investigations were done in neutral and six basic emotions collected from...
Phonetic Engine (PE) is the first stage of automatic speech recognition system that converts input speech to a sequence of phonetic symbols. A baseline phonetic engine is created using Malayalam speech database. A Graphical User Interface (GUI) is developed for the phonetic engine to perform real time recognition of phonemes. It is known that higher level of speech information such as intonation,...
The real time biometric systems are used to authenticate persons for various applications. In this paper, we propose an efficient VLSI architecture for fingerprint recognition using O2D-DWT architecture and modified CORDIC-FFT. The O2D-DWT architecture is designed using only adders and shifters for high speed operation and is applied on fingerprint image to generate four sub-bands. The optimized Fast...
In this paper, a new set of features for addressing the problem of unsupervised query-by-example spoken term detection is proposed. The main purpose of this is to find a spoken query in large speech databases. In unsupervised audio search, language specific resources are not required. Thus this system is more appropriate in cases where enough training data is not available for creating an Automatic...
