Change the SAPI Microsoft Speech Object Library Voice with Delphi code

I'm using the 'Microsoft Speech Object Library' and I would like to change the default voice through delphi code.

My default voice is a woman speaking. How do I change it to someone else if someone else is available?

I'm using SAPI 5.4 and Delphi XE6.

You did not say which version of SAPI you are using, or show the code you are using to invoke SAPI with.

For instance, in SAPI 5, the ISpVoice interface has a SetVoice() method, where you pass it a ISpObjectToken interface for a specific voice. To get the ISpObjectToken, you can:

ISpVoice

SetVoice()

ISpObjectToken

ISpObjectToken

use SpEnumTokens() to enumerate available voices until you find one you want.

SpEnumTokens()

use SpFindBestToken() to find a voice that matches various criteria you specify.

SpFindBestToken()

use SpCreateNewToken() or related function if you know the specific voice you want to use.

SpCreateNewToken()

SPVoice1.Speak()

SPVoice1.SetVoice()

SPVoice1.Speak()

SPVoice1.SetVoice()

SPVoice1.Speak()
