Experimental studies conducted on two different continuous speech recognition tasks show that systems using only context-dependent graphemes can yield competitive performance when compared to state-of-the-art context-dependent phoneme-based automatic speech recognition system. We further demonstrate that a system using both context-dependent phoneme and grapheme subword units can out perform either of these systems alone.}, pdf = {https://publications.idiap.ch/attachments/reports/2005/rr05-16.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2005/rr05-16.ps.gz}, ipdmembership={speech}, }
