Relying on code that can only be generated with a proprietary tool is touchy.
Are there existing speech models which can be shipped under an appropriate license? Are speech models binary blobs akin to byte-compiled code java or python (ie. not allowed in Fedora)? Or are the speech models themselves self documenting scripts that are then interpreted at run time by Simon? Could I realistically write or edit a speech model manually. If Fedora did choose to ship a pre-existing speech model generated by the proprietary tool and there was a bug found in the speech model, what steps would the Fedora maintainer of Simon need to take to fix the problem?
If Simon needs at least one speech model locally to be useful...we'd have to understand what the speech models are in terms of codebase and the implications thereof.
