查询词典 echo speech

According to the difference of Doppler spectra of meteor trail echo and clutter of ground and sea, a FIR high-pass filter is designed to filter out clutter and so the meteor trail echo becomes obvious. Then a smart threshold is obtained from the minimum mean of different segments of background noise and used to detect the meteor trail echo. Finally the phase discontinuity of clutter from the meteor trail echo suppression is eliminated by substituting the data at echo positions with clatter.

Prosodic research on Chinese characters plays a great role in speech recognition and speech synthesis system. In order to improve the naturalness of a speech synthesis system, the relationship among the sentence structure, the length of a sentence and the breath boundaries is analyzed and a breath boundary assigning algorithm based on such relationship is put forward. In addition, the author analyzes the process of a speech synthesis system and builds a prosodic markup language suitable for Chinese speech synthesis.

G. speech perception and understanding. These stages are described and interpreted in terms of the findings from recorded corpus and questionnaires in education. As for speech production, students' speech motives are explored in detail. Speaker's speech intention is interpreted in connection with listener's reception of it. Findings are presented to show that, in the course of formulating speech plan, the previous sentences is often processed, the construction of sentence is a process of accumulative expansion of speech items through sequential or inversive appending or insertion, and the interaction between long-term and short-term speech plans often occurs.
