Google does not always create accessible products (GoogleWave). However, sometimes they do a good job of increasing the accessibility of an existing service. I hope that Vimeo gets the message that accessibility is important.
In the first major step toward making millions of videos on YouTube accessible to deaf and hearing-impaired people, Google unveiled new technologies that will automatically bring text captions to many videos on the site.
[Google] combined their automatic speech recognition (ASR) technology with the YouTube caption system to offer automatic captions, or auto-caps for short. Auto-caps use the same voice recognition algorithms in Google Voice to automatically generate captions for video.
