Philips provides a sophisticated API running on the
internal 80C51, allowing product developers to design
their MMIs quickly to suit particular applications. The API
takes care of all flash memory and DSP management
tasks and can be enhanced on request.
For the pre-recorded voice prompts, the Philips
International Language Library (PILL) tools are available
for a standard multimedia PC platform under Windows 95.
These tools provide a way to compile a range of
multi-lingual voice prompts for efficient storage in the
speech (flash) memory. The PILL tools support various
languages and their grammar adaptations.
Metalink emulation is supported with the standard
package.
