The design and selection of them will directly impact the performance of final speech recognition engine. As a tonal language, Mandarin\u2019s modeling units are more special for the tonal processing. In this paper, after fully investigating several dominant modeling strategies, we propose a new phone set design strategy for Mandarin, called segmental tonal modeling. Instead of modeling tone types directly, we realized them implicitly and jointly by two segments, which both carry tonal information. Both HTK and SAPI based experiments confirmed that such method is very efficient. In addition to improving the accuracy by 9~23%, it greatly reduces the decoding time by 30~45%. Given the similar decoding speed, new phone set configuration can reduce the error rate by relatively 35%.<\/p>\n<\/div>\n<p><!-- .asset-content --><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Modeling units play a very important role in state-of-art speech recognition systems.
