Sphinx knowledge base tools

Language Factory

The Logios package is available on SourceForge.

The following tool accesses the pronunciation component of Logios:
LexTool allows you to upload word lists and creates pronunciations for them.

Sphinx Configuration

Decoder Configurer (a)
Creates Sphinx lexical and language models from a sentence corpus provided by the user. Suitable for use with all Sphinx variants.
