This paper proposes simultaneous decoding using multiple utterances to derive one or more allophonic transcriptions for each word. Three possible simultaneous decoding algorithms, namely the N-best-based algorithm, the forward-backward-based algorithm and the word-network-based algorithm, are outlined. The proposed word-network-based algorithm can(More)
This study is to establish an UPLC fingerprint of Resina Draconis from different manufacturers, which can provide a comprehensive evaluation for its quality control. The analysis was performed on a Phenomenex Kinetex 2.6 μ C18 100A column by agradientelution program with acetonitrile-water as mobile phase at a flow rate of 1.7 mL x min(-1). The column(More)
This study aimed to monitor liquid-liquid extraction of Gardenia jasminoides Ellis (Zhizi in Chinese) using in-line near-infrared spectroscopy. Shanzhiside (SZS), deacetyl asperulosidic acid methyl ester (DAAME), genipin-1-β-D-gentiobioside (GG), geniposide (GS), total acids (TA) and soluble solid content (SSC) were selected as quality control indicators,(More)
OBJECTIVE To establish a rapid quantitative analysis method for the content of chlorogenic acid and solid content in the extraction liquid concentration process during the production of Reduning injection by using the near-infrared (NIR) spectroscopy, in order to reflect the concentration state in a real-time manner and really realize the quality control of(More)
OBJECTIVE To control the quality of the product, quantitative fingerprint was used to evaluate the composition of the amino acids in the Xingnao Tongluo injection. METHOD The method of the quantitative fingerprint to the amino acids composition was established through AccQ Tag precolumn derivatization. The quality was evaluated by the quantitative test of(More)
This paper is to investigate the optimization conditions of ultrasonic technique for extraction process of Xiaoqinglong granules in medium scale. First of all, single factor experiment was used to determine the overall impact tendency and range of each factor; secondly, Box-Behnken method was used for optimization and detecting the content of paeoniflorin,(More)
The distribution ol feature vectors derived from short speech segments is considered a mixture of Gaussian densities. Each density corresponds to a phonetic state in the speech production process and is trained by the observed feature vectors derived from waveform segments corresponding to a specific phoneme. We propose in this paper that a short utterance(More)
