Is there any replacement for Voice Dial for the HP PRE 3, using v2.2.4?

Or, is there any way to overide the language?

My phone is set to English, but I am a native Spanish speaker. I think my phone does not understand my accent (it is expecting an English pronunciation, I think).

Can I replace it? Can I make it understand Spanish language (without having to change the whole OS to Spanish)?

I'd like to know what experiences you might have had similar to this...
