A continuous speech recognition system using phonotactic constraints

This paper describes a speaker-independent recognition system for continuous German speech based on semicontinuous Hidden-Markov-Models which produces a phonetic transcription of the spoken sentence. The recognition units are parts of syllables while the output is a phoneme level transcription. During recognition, the phonotactic constraints of German are taken into account by a micro syntax constrained Viterbi algorithm. A maximum likelihood training procedure based on Viterbi training together with a simple but efficient seed model generation algorithm is presented

A continuous speech recognition system integrating additional acoustic knowledge sources in a data-driven beam search algorithm

The paper presents a continuous speech recognition system which integrates an additional acoustic knowledge source into the data-driven beam search algorithm. Details of the object oriented implementation of the beam search algorithm will be given. Integration of additional knowledge sources is treated within the flexible framework of Dempster-Shafer theory. As a first example, a rule-based plosive detector is added to the baseline system

Zwei seltene Porlinge im Vergleich

In hyrkanischen nemoralen Laubmischwäldern am Kaspischen Meer wurden die in Mitteleuropa seltenen Porlinge Perenniporia fraxinea und Rigidoporus ulmarius nachgewiesen. Die Funde sind Anlass für eine vergleichende Studie der beiden oft verwechselten Arten
