#1 Cross-language bootstrapping for unsupervised acoustic model training: rapid development of a Polish speech recognition system [PDF] [Copy] [Kimi1]

Authors: Jonas Lööf ; Christian Gollan ; Hermann Ney

This paper describes the rapid development of a Polish language speech recognition system. The system development was performed without access to any transcribed acoustic training data. This was achieved through the combined use of cross-language bootstrapping and confidence based unsupervised acoustic model training. A Spanish acoustic model was ported to Polish, through the use of a manually constructed phoneme mapping. This initial model was refined through iterative recognition and retraining of the untranscribed audio data.
