Grapheme based speech recognition for large vocabularies
Christoph Schillo, Gernot A. Fink, Franz Kümmert · 2000
Common speech recognition systems use phonetically motivated subword units. To utilize words in these systems, one has to translate the available graphemic word representation into a phonetic one. To reduce this manual effort we propose to build grapheme based recognition systems. They can be used as speech interfaces for devices that can provide a graphemic representation of words like city names of navigation systems. Results of experiments on a 10,000 word lexicon of German cities are presented. 1.
