Localizing SAPI Text-To-Speech to spanish
I have managed to use SAPI Text-To-Speech in Delphi/Lazarus by using the following code:
procedure TForm1.Button1Click(Sender: TObject); var SpVoice: Variant; begin SpVoice := CreateOleObject('SAPI.SpVoice'); SpVoice.Speak('Hello World!', 0); end;
This code automatically chooses an english standard voice. Since I need to localize it to spanish I investigated if my system (Windows XP with standard Spanish) had a spanish voice or I needed to install it, and how to change the default voice, but no luck so far. Therefore my questions are:
- How can I know if my system already has a spanish voice installed or I need to install it?
- Supposing I have the voice I need installed, how can I make SAPI use that voice instead of the standard one?
I am guessing I can get a spanish voice by using following code (C0A is the code for spanish language):
but do not know how to set the voice to be used.
EDIT: to avoid confusions, I need to make this compatible with Delphi and Lazarus, being the last one the primary development tool.
No freely available version of SAPI comes packaged with a Spanish voice. SAPI 5.1 for XP comes with a Chinese and English voice; SAPI 5.3 and SAPI 5.4 have only English voices installed.
You can purchase a Spanish voice from Cepstral (among other vendors) that will work for any version of SAPI 5. (I have not used these voices, so I cannot vouch for the quality of these voices.)
