PermA and Balloon: Tools for string alignment and text processing
Two online research tools are presented in this paper: PermA, a general purpose string aligner which can for example be used for grapheme to phoneme and phoneme to phoneme alignment, and Balloon, a text processing toolkit for German and English providing components for part of speech tagging, morphological analyses, and grapheme to phoneme conversion including syllabifica tion and word stress assignment. The general architectures of these tools are introduced with a focus on recent improvements concerning the alignment cost function derivation and word stress assignment.
