Embodiment Construction

[0047] figure 1 is a block diagram illustrating an information retrieval system based on a bilingual speech query according to an exemplary embodiment of the present invention. Such as figure 1 As shown, the system includes a feature extractor 101 , a bilingual phoneme recognizer 102 , a bilingual character-to-phoneme (G2P) converter 103 , and a vocabulary comparator 104 . figure 1 The MP3 ID3 tag database shown in is the input to the bilingual G2P converter 103 . The feature extractor 101 is used to extract a MFCC feature parameter specific to speech recognition from the PCM waveform file. Considering the channel distortion of various microphones, the present invention adopts a noise reduction algorithm to eliminate the distortion. In addition, the present invention adds a frame compression module to increase the processing speed on the mobile platform. The basic idea of ​​frame compression is to compress several adjacent MFCC frames into one frame by linear interpolation...

Abstract

The invention provides an information retrieval system and a method based on bilingual phonetic query. The system comprises: a character extractor which is used for converting a phonetic signal from PCM waveform into an MFCC characteristic parameter and outputting a compressed MFCC data flow after the noise suppression and frame compressing processing; a bilingual phoneme recognizer which is used for receiving the compressed MFCC data flow and executing the speech recognition by automatically converting English or Chinese speech into text phoneme series; a bilingual character phoneme converter which is used for converting character level series of available contents used for the speech retrieval of MP3 files in an MP3 ID3 label database into phoneme level series used as referential phoneme series; a vocabulary comparator which is used for comparing the recognizing phoneme series generated from the bilingual phoneme recognizer with the referential phoneme series generated from the bilingual character phoneme converter and outputting the most related front N referential phoneme series.

Description

technical field [0001] The system and method according to the present invention relate to an information retrieval system and method for bilingual voice query based on an embedded device. Background technique [0002] Today, mobile electronic products such as PDAs, cellular phones, MP3 players and GPS navigators have become necessary tools for obtaining information or multimedia content. In China, there has been a great increase in the number of users using wireless services. Every day, more than 500 million mobile phone users enjoy communication, ring tone download and short message services. With the decreasing price of memory with large storage capacity and the coming of high-speed 3G wireless network, people can freely download a large amount of information from wireless channels and store it in their mobile devices. Under such conditions, it is not practical to search for required data one by one as in the conventional method. For any large storage device, fast and a...
