The IEEE 802.16e standard defines a sleep mode operation for conserving power to support the battery life of mobile broadband wireless access (BWA) devices. The system saves energy when it goes through a sleep period with some delay in packet arrival response time. The relationship between energy consumption and the delay is studied to ensure best performance for mobile devices. This relationship has been analyzed by using a mathematical model. A new scheduling method is proposed to adjust the sleep cycle periods by adding a small increase to the next sleep cycle compared with the previous cycle instead of just simply doubling the previous cycle. The simulated results were obtained after adjusting the length of the first sleep cycle period (Tmin ). Adjusting Tmin provides a result of 54% reduction in the time needed for every frame to get a response especially in a lower traffic region. In a high traffic region, a reduction of 21.5% has been obtained in energy consumption for each sleep mode operation. Therefore, the proposed idea confirms a faster frame response time at lower energy consumption.

Determinism in speech pitch relation to emotion

Author: Mahmoud, Ahmed Mustafa ; Hassan, Wan Haslina

Emotional speech synthesis is traditionally achieved using time-pitch manipulation of the synthesized acoustic waveform. Rule-based approaches rely on rules that describe the behavior of the pitch frequency along time to generate time-pitch values. Pitch values fluctuate within a certain range depending on the intended emotion. Recent studies in emotional cognitive psychology have shown that a slight 4 Hz modification of pitch frequency is sufficient to make significant change in the emotional state of speech. Existing rule-based approaches neglects this determinism by relying on statistical approaches, thus increasing the probability of error. In this paper, a deterministic approach to emotional speech rule-based synthesis algorithm is presented. This approach relies on mapping the pitch frequency values to the 12 semitone melodic scale and extracting semitonic intervals for each emotional state. Using praat analysis tool, emotional speech samples are analyzed and semitonic intervals are extracted. An objective evaluation was used to determine the accuracy of this approach by comparing the simulated speech to natural speech under the intended emotion. Results show that this approach has marked improvements with a low mean square error of no more than 2.65 semitones.
