===Other audio enhancements===
* A new set of user interface sounds have been introduced, including a new startup sound created with the help of [[King Crimson]]'s [[Robert Fripp]].<ref name="Channel9Fripp">{{cite web |url=http://channel9.msdn.com/Blogs/scobleizer/Robert-Fripp-Behind-the-scenes-at-Windows-Vista-recording-session |title=Robert Fripp - Behind the scenes at Windows Vista recording session |last=Scoble |first=Robert |authorlink=Robert Scoble |date=January 4, 2006 |publisher=[[Microsoft]] |work=[[Channel 9 (Microsoft)|Channel 9]] |accessdate=April 25, 2015}}</ref> The new sounds are intended to complement the [[Windows Aero]] [[graphical user interface]], with the new startup sound consisting of two parallel melodies that are played in an intentional "Win-dows Vis-ta" rhythm. According to [[Jim Allchin]], the new sounds are intended to be gentler and softer than the sounds used in previous versions of Windows.<ref name="WindowsVistaSounds">{{cite web |url=http://windowsvistablog.com/blogs/windowsvista/archive/2006/11/09/the-sounds-of-windows-vista.aspx |title=The Sounds of Windows Vista |last=Allchin |first=Jim |authorlink=Jim Allchin |date=November 9, 2006 |archiveurl=https://web.archive.org/web/20061110152317/http://windowsvistablog.com/blogs/windowsvista/archive/2006/11/09/the-sounds-of-windows-vista.aspx |archivedate=November 10, 2006 |publisher=[[Microsoft]] |work=Windows Vista Team Blog |accessdate=April 25, 2015}}</ref>

Different sounds can be redirected to different audio devices as well.
* Windows Vista includes integrated [[microphone array]] support which is intended to increase the accuracy of the [[Technical features new to Windows Vista#Speech recognition|speech recognition]] feature and allow a user to connect multiple microphones to a system so that the inputs can be combined into a single, higher-quality source.<ref name="AudioImprovements"/><ref name="AudioInnovationsWP">{{cite web |url=http://blogs.technet.com/b/windowsvista/archive/2006/08/24/450038.aspx |title=Audio Innovations in Windows Vista |date=August 24, 2006 |publisher=[[Microsoft]] |work=[[Microsoft TechNet|TechNet]] |accessdate=April 25, 2015}}</ref><ref name="MicrophoneArray">{{cite web |url=http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/MicArrays.doc |title=Microphone Array Support in Windows |date=April 21, 2014 |author=[[Microsoft]] |format=DOC |accessdate=April 25, 2015}}</ref>
Microsoft has also included a new high quality voice capture [[DirectX]] Media Object (DMO) as part of [[DirectShow]] that allows voice capture applications such as [[instant messaging|instant messengers]] and speech recognition applications to apply [[Echo cancellation#Acoustic echo cancellation|Acoustic Echo Cancellation]] and microphone array processing to speech signals.<ref name="AcousticEcho">{{cite web |url=https://technet.microsoft.com/en-us/library/cc753619.aspx |title=Eliminating Acoustic Echo |publisher=[[Microsoft]] |work=[[Microsoft TechNet|TechNet]] |accessdate=April 25, 2015}}</ref>

Windows Vista includes speech recognition for 8 languages at release time: English (U.S. and British), Spanish, German, French, Japanese and Chinese (traditional and simplified). Support for additional languages is planned for post-release.
Speech recognition in Vista utilizes version 5.3 of the [[Microsoft Speech API]]<ref name="winspeech">
Windows Vista, SAPI [http://msdn.microsoft.com/msdnmag/issues/06/01/speechinWindowsVista/ Talking Windows] {{Webarchive|url=https://web.

===Speech synthesis===
{{main|Microsoft text-to-speech voices}}
Speech synthesis was first introduced in Windows with [[Windows 2000]], but it has been significantly enhanced for Windows Vista (code name [http://research.microsoft.com/users/minchu/Microsoft%20Mulan.htm Mulan]). The old voice, [[Microsoft Sam]], has been replaced with two new, more natural sounding voices of generally greater intelligibility: [[Microsoft Anna|Anna]] and [[Microsoft Lili|Lili]], the latter of which is capable of speaking Chinese. The screen-reader [[Microsoft Narrator|Narrator]] which uses these voices has also been updated. [[Microsoft Agent]] and other text to speech applications now use the newer SAPI 5 voices.<ref name="audiospeechdemo">[http://microsoft.sitestream.com/PDC05/PRS/PRSL03_files/Default.htm#nopreload=1&autostart=1 Vista Speech Demo] {{Webarchive|url=https://web.archive.org/web/20060527003044/http://microsoft.sitestream.com/PDC05/PRS/PRSL03_files/Default.htm#nopreload=1&autostart=1 |date=2006-05-27 }} from the Professional Developers Conference 2005 (link requires Internet Explorer)</ref>

* The '''[[Offline Files]]''' feature, which maintains a client-side cache of files shared over a network, has been significantly improved. When synchronizing the changes in the cached copy to the remote version, the ''Bitmap Differential Transfer'' protocol is used so that only the changed blocks in the cached version are transferred, but when retrieving changes from the remote copy, the entire file is downloaded.<ref name="Offline">{{cite web | url = http://windowsvistablog.com/blogs/windowsvista/archive/2007/01/29/working-with-offline-files.aspx | title = Offline Files | author = Jim Allchin | accessdate = 2007-06-14 | archive-url = https://web.archive.org/web/20070518233509/http://windowsvistablog.com/blogs/windowsvista/archive/2007/01/29/working-with-offline-files.aspx | archive-date = 2007-05-18 | dead-url = yes | df = }}</ref> are synchronized on a per-share basis and encrypted on a per-user basis and users can force Windows to work in offline mode or online mode or sync manually from the Sync Center. The Sync Center can also report sync errors and resolve sync conflicts. Also, if network connectivity is restored, file handles are redirected to the remote share transparently.
* '''Delayed service start''' allows services to start a short while after the system has finished booting and initial busy operations, so that the system boots up faster and performs tasks quicker than before.
* '''Enable advanced performance''' option for hard disks: When enabled, the operating system may cache disk writes as well as disk reads. In previous Windows operating systems, only the disk's internal disk caching, if any, was utilised for disk write operations when the disk cache was enabled by the user. Enabling this option causes Windows to make use of its own local cache in addition to this, which speeds up performance, at the expense of a little more risk of data loss during a sudden loss of power.
