Robust Keyword Spotting using The Isolated Word Recognition
Wataru Takahashi, Yoshikazu Miyanaga (Hokkaido Univ.) SIS2011-37
Abstract (in Japanese) (See Japanese page) 
(in English) In this report, we performed a keyword spotting from cotinuous speech under noisy environments. The proposed algorithm is based on the robust isolated word recognition and it is applied for the continuous speech. Super parallel calculation mechanism is embedded into the proposed method. We can realize real time processing using its parallel structure in a hardware system.
This paper calls super-parallel automatic speech recognition (SP-ASR).
The method can estimate the section of the keywords and recognize it from continuous speech. If a speech except the keywords and non-speech are given during this recognition, the recognition accuracy is degraded.
Therefore, the new processing which rejects the unsuitable results is necessary.By using the likelihoods into speech recognition, the new rejection algorism is
implemented.
Some recognition results are computed by SP-ASR and the reliability of the recognition and the rejection can be improved.
We finally show a result that high recognition ratio could be obtained by
performing keyword spotting in SP-ASR from continuous speech under noisy environments.
