Outline
- Intro
- Unit Selection
- Mistake instance
- Unit
- Replacement
- Multwords
- Baseline Description
- Vocab: single most frequent pronunciation from a multi-pronunciation dictionary (better than multi-pronunciation)
- Results
- what to emphasize? Ideally, units+DTs will beat just DTs for every number of components. Even if we cannot grow the components until improvement bottoms out, at least there will be a trend.
- Conclusion
- Future work: consider context during unit selection (right now the unit is context-free - the same unit appearing in all contexts where replacements took place).
