Is it possible to output several voices in one audio file?

[WantToKnow]

Code: Select all

spVoice1 := ComObjCreate("SAPI.SpVoice")
spVoice1.Volume := 100 
spVoice1.Rate := -3
spVoice1.Voice := spVoice1.GetVoices().Item(0)  ; Voice 1
spVoice1.AllowAudioOutputFormatChangesOnNextSet := 1

spVoice2 := ComObjCreate("SAPI.SpVoice")
spVoice2.Volume := 50
spVoice2.Rate := 1
spVoice2.Voice := spVoice2.GetVoices().Item(4) ; Voice 2
spVoice2.AllowAudioOutputFormatChangesOnNextSet := 1

; works fine:
SpVoice1.Speak("This is the voice of Brian.")
SpVoice2.Speak("This is the voice of Sally.")

strWav := "Test.wav"
spStream := ComObjCreate("SAPI.SpFileStream")
SpStream.Open(strWav,3,1) ; Error

Is it possible to speak simultaneously with several voices on one audio file?

I believe the answer is yes. On cellphone at the moment will have to sit with my computer for a test and code

Sorry I misunderstood the question as speaking two voices at the same time. I don't know anything about file output.

Thanks for your answers. I already solved it and it's possible.
Once you have constructed the Sapi voice objects, it is exactly the same as with a voice.
