VMS Help RTL Routines, DTK$, DTK$SET_VOICE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   The Set Voice Characteristics  routine  changes  the  DECtalk  voice
   characteristics to match those specified.

      Format:

        DTK$SET_VOICE  voice-id [,new-voice] [,speech-rate]
                   [,comma-pause] [,period-pause]

      Arguments:

   voice-id

   OpenVMS usage: identifier
   type:          longword (unsigned)
   access:        read only
   mechanism:     by reference

   Voice identifier of the DECtalk device.  The  voice-id  argument  is
   the address of an unsigned longword containing this identifier.  The
   voice identifier is returned by the DTK$INITIALIZE routine.

   new-voice

   OpenVMS usage: longword_signed
   type:          longword (signed)
   access:        read only
   mechanism:     by reference

   Type of voice.  The optional new-voice argument is the address of  a
   signed  longword containing any valid new-voice value.  Valid values
   for new-voice are:

        DTK$K_VOICE_MALE               Standard male voice

        DTK$K_VOICE_FEMALE             Standard female voice

        DTK$K_VOICE_CHILD              Standard child voice

        DTK$K_VOICE_DEEP_MALE          Deep male voice

        DTK$K_VOICE_DEEP_FEMALE        Deep female voice

        DTK$K_VOICE_OLDER_MALE         Older male voice

        DTK$K_VOICE_LIGHT_FEMALE       Light female voice

   speech-rate

   OpenVMS usage: longword_signed
   type:          longword (signed)
   access:        read only
   mechanism:     by reference

   Rate at which DECtalk speaks, measured in  words  per  minute.   The
   optional  speech-rate  argument  is the address of a signed longword
   containing this rate.  The valid range of values for speech-rate  is
   120 to 350 words per minute.

   comma-pause

   OpenVMS usage: longword_unsigned
   type:          longword (unsigned)
   access:        read only
   mechanism:     by reference

   Number of milliseconds by which to increase the time DECtalk  pauses
   after  a comma.  The optional comma-pause argument is the address of
   a signed longword containing this number.  A value  of  zero  resets
   the pause time to the hardware default value.

   period-pause

   OpenVMS usage: longword_unsigned
   type:          longword (unsigned)
   access:        read only
   mechanism:     by reference

   Number of milliseconds by which to increase the time DECtalk  pauses
   after  a  period.  The optional period-pause argument is the address
   of a signed longword containing this number.  A value of zero resets
   the pause time to the hardware default value.
