Abstract: The method and system disclosed herein reduces total bandwidth requirement for communication in a voice over Internet protocol application. Sample [101] and convert [102] the analog input audio signal into digital signals and derive sampled frames [103]. Compute spacings of order statistics [104]. Measure the entropy for each of the sampled frames [105]. Set a threshold for entropy [106]. Mark the audio frames as active speech frames or inactive speech frames [107]. Mark an audio frame as an' inactive speech frame when the entropy is greater than the threshold, and mark the audio frame as an active speech frame when the entropy is lesser than the threshold [107]. Transmit only the active speech frames [108].

Abstract: Disclosed herein is a computer implemented method and system for determining presence of a first user by a second user in an online environment. The first user provides the first user's profile information and characteristic information. The first user marks keywords in the characteristic information. The first user marks the keywords based on inference of second user's knowledge about the first user. The marked keywords are categorized into predefined categories. The second user provides search words. The search words are compared with the characteristic information and the keywords to find matches. The matches are weighted. Search indexes are generated for the weighted matches based on a predetermined criterion. The weighted matches with the generated search indexes are provided to the second user. The selected profile information corresponding to the predefined categories comprising the categorized keywords for which the weighted matches have high search indexes, is displayed to the second user.
