Its funny but I can go onto the web and speak to the phone for a web search, but I can't figure out how to send a text message by talking instead of typing. I tried going to Menu>Settings>Text-to-speech>Install voice data, but the install voice data is greyed out. So I went to the Market place and installed the Speech Synthesis Data Installer and still the Install voice data is greyed out. Does anyone have a solution? How to I talk to text on the vibrant?
