The title says it all, why doesn’t unity add support to System.Speech
Sorry for necro, but I would like to know this too.
The mono version that unity uses does not include System.Speech.
System.Speech is only available from .net 4.x and up but the mono version unity uses is a mix of dotnet 2 and 3 but not 4.
Maybe for windows phone it may be available as that platform uses .net directly and not mono.
