Unsupervised and phonologically controlled interpolation of Austrian German language varieties for speech synthesis
We present a method for interpolation between language varieties for speech synthesis. The method is unsupervised, based on dynamic-time-warping. Phone sets and formant analysis for four Austrian language varieties are presented. Subjective evaluation shows that listeners can perceive the intermediate variants. Inclusion of switching rules increases the dialect authenticity of the synthesis.
