Modules
IPOX uses three types of grammars to analyze input text:
- syntactic component (syn)
- morphological component (mor)
- phonotactic and prosodic component (phon)
The run-time system uses these modules to parse:
- orthographic words (syn)
- substrings of a word (mor)
- characters in a word (phon)
Properties:
- each module can be designed and tested separately
- the syntactic component can be interfaced to the morphological component
Limitations:
- no interface has yet been defined between syntax/morphology and phonology
- speech can be generated only from a representation assigned by the phonotactic/prosodic component
Syntax-Morphology interface:
- function words are defined in the lexicon of the syntactic component
- content words are analyzed by the morphological component
Example:
In the example below, adaptable and system are analyzed by the morphological component.

In order to generate speech for this utterance, we need the structure shown below.
