The JavaScript Web Speech API enables speech-to-text on the desktop web. Check out this cool tutorial and demo to learn how to add speech to your webpages.

For speed junkies, the Resource Timing API exposes detailed timing information to JavaScript about subresources loaded by the page, and the User Timing API provides access to high-precision timestamps to help measure web app performance.

Chromium's IndexedDB implementation now supports concurrent transactions. Some web apps may inadvertently rely on sequential transactions, so be sure to test yours in today’s Beta.

Various IndexedDB features have been updated to match the spec: setVersion has been replaced with the new upgradeneeded API, and a few old constants have been removed.

The Web Audio API now exposes an OfflineAudioContext constructor, and a few AudioContext method names have been updated to match the latest spec. Note that Chrome for Android doesn’t support the Web Audio API yet.

The ::cue pseudo-element lets you style WebVTT cues such as HTML5 video subtitles.
