## Discussion

Discussion A voice specification structure is a unique voice ID usedby the Speech Synthesis Manager. Most voice management functionsexpect to be passed a pointer to a voice specification structure.When you already know the creator and ID for a voice, you shoulduse the MakeVoiceSpec functionto create such a structure rather than filling in the fields ofone directly. On exit, the voice specification structure pointedto by the voice parameter containsthe appropriate values. You should never set the fields of sucha structure directly.
