To use voice typing in Google Docs simply open the "tools" drop-down menu and select "voice typing." When you make that selection a microphone icon will appear in the margin of your document. Once the icon appears, click it, allow Google to access your microphone, and start talking. Your spoken words will almost instantly appear on in the document.
A complete set of voice typing functions is available here.
