Directory of Speech Synthesis Cores Resources

Home > Computers > Speech Technology > Speech Synthesis > Speech Synthesis Cores

This category houses sites which provide the basic speech synthesis engines, whether multi-lingual or not, whether from academia or commercial sources. An "engine" or "generator" or "core" here is considered to be something which only produces speech as output when given text as input, but does not do this for any larger purpose or function. These "cores" are more or less general engines, developed, designed, created or produced by the site owner. They would be used to power or provide speech for other applications and can be expected to be embedded in or otherwise be a component of those applications. The other applications might be things like interactive voice response units, page readers, handheld dictionaries, language translators and so forth.
