ReadSpeakerTTS

Was wondering if anyone has been able to install . I’m stuck trying to install the voices, which come as separate files. I’ve added one to the plug-in directory. The instructions say to “Open the ReadSpeakerTTS settings window.” as part of the install process in order to scan for voice. Does anyone know where to find this window? I’m in my project, but not sure where the settings would be. I tried adding a TTSSpeaker object, but its settings just say no voices available.
