The download page for those voices says, "Note that Nuance RealSpeak Solo SAPI 5 and Direct Driver voices do not support pitch change like Eloquence and some other hardware and software synthesizers." ----- Original Message ----- From: Kim Loftis To: jfw@xxxxxxxxxxxxx Sent: Saturday, July 04, 2009 11:55 AM Subject: Recognizing Capital Letters Using Realspeak Synthesizer Hi All, This morning I installed two voices that are part of the Realspeak synthesizer. I'm really enjoying both of them, but I have one question. I no longer hear any difference in pitch between letters that are capitalized and those that are not. I have the pitch change rate set to -20 on both voices, but still notice no difference whatsoever. Does anyone have any suggestions that might help? The voices I'm using, if anyone's interested, are Serena and Samantha. Thanks Much, Kim
