Currently there is no library for speech recognition on WP7 but you can use speech recognition through a service.

You can find here an example on how to use speech recognition on Windows Phone 7 through a service:

Windows Phone 7 Prototype 001: Speech Recognition on WP7

There's no public API available for this yet. You can register at Microsoft Tellme to get information on when it's done.

Also take a look at Microsoft Project Hawaii.

Has there been any updates on Tellme's API? Their website is quite vague. I see SAPI, but there's not mention of using it for Windows Phone.
