Insight Into

People use their voices to communicate not only verbally but also emotionally. This article presents theories and methodologies that concern emotional vocalizations at the intersection of psychology and digital signal processing. Specifically, it demonstrates the encoding (production) and decoding (recognition) of emotional sounds, including the review and comparison of strategies in database design, parameterization, and classification. Whereas psychology predominantly focuses on the subjective recognition of emotional vocalizations, digital signal processing relies on automated and thus more objective vocal affect measures. The article aims to compare these two approaches and suggest methods of combining them to achieve a more complex insight into the vocal communication of emotions.

Array Multiplier

The multiplication operation is one of the often used operation in many computer and electronic devices. Low power utilization is one of the most essential attributes for meeting several challenges in many applications. In this paper different type of implementation of Booth multiplier has been studied. Multipliers has great importance in digital signal processing, so designing a high speed multiplier is the need the hour. Structures of 4X4 bits Urdhva Tiryagbhya, Nikhilam Sutra have been executed on Spartan 3 XC3S50-5-PQ-208.The determined calculation delay for 4X4 Urdhva Tiryagbhyam was 14.14 ns and force is 20.60 mw. For Nikhilam Sutra the determined computational postponement is 16.16 ns and all out force utilization is 24.60 mw.
