Nolan Darilek	4f011e6895	Get Tolk working again. ... Two Tolk instances were being created. One checked for the presence of a screen reader. The other actually performed the speech, and was returned as part of the `TTS` instance. Unfortunately, Tolk doesn't seem to appreciate being called twice. So here we check if a screen reader is detected and, if one is, return the instance that did the detection. Otherwise, error out and return the WinRT backend.	2020-06-11 13:00:24 -05:00

Nolan Darilek	7b4fb8dae4	Clean up speech synthesis properties, and implement everything for WinRT. ... I'd previously attempted to normalize everything to `u8`, but this had some drawbacks: * It failed to account for some synthesis drivers defining normal as mid-range, while most define it very low. * It didn't track the normal value for a given synthesizer. * There was no clean way to map a curve between the minimum, normal, and maximum rates. Here we track the minimum, normal, and maximum values of rate, pitch, and volume. Sanity checks are done on set. Also, as a further proof-of-concept, all properties are now implemented for the WinRT driver.	2020-05-18 18:12:59 -05:00
