Got Balabolka running in Crossover Linux (Mint 18) with some obsolete SAPI 4 voices fairly easily. (Installed the .Net Framework v4.5.1)
Following suggestions in the TextAloud Program Crossover forum I could install some SAPI 5 voices but not any of the newer/better voices. Voice quality is still very poor. There are some better SAPI 5 voices out there (especially some of the commercial ones), but the Windows runtime SAPI 5.1 installers seem to fail consistently. The newer 32 bit Windows Speech platform runtime and voices seem to download and install okay, but Balabolka gives the error:
Can not synthesize the speech:
OLE error 80004005
Any suggestions for installing SAPI 5.1 voices or resolving the Speech Platform error?
