How to enable Cortana on non-US Windows Phone 8.1 devices

Published by at

If you've installed the latest Windows Phone Developer Preview release you now have access to a preview version of Windows Phone 8.1. However, if you're outside the US you will not have access to Cortana, the personal digital assistant that is one of the headline features of the latest version of Windows Phone. It is possible to enable Cortana on any device, but there are some important caveats to be aware of.

Cortana is currently described by Microsoft as being in beta and is only available in the US. It is expected to lose the beta label and be made available in the UK and China in the second half of the year. Availability in other markets will follow in 2015. This market availability is due to both the need to optimise the speech recognition for different markets and to create the supporting localised knowledge graph on which Cortana relies.

While Microsoft has a good reason for keeping Cortana georestricted, it does not stop those outside the US being curious about how Cortana operates.

To enable Cortana you will need to change some localisation settings, but it is important to realise this may have an impact on how you use your device. For example, speech recognition and other location specific service may be impacted. Some geo-restricted services (e.g. Xbox Music and Xbox Video may also be effected). 

How to enable Cortana on a non-US device

  • Change the language settings to "English (United States)" in the language module of the standard Windows Phone Settings app. This is done by first adding the language (requires a download) and then enabling the language (requires a reboot). Changing the language should also change the speech language, but if it does not you can do this via the speech module in the Settings app (download of speech data files may be required).
  • Change the region setting to "United States" in the region module of the standard Windows Phone Settings app. You should also check that region format is set to "match phone settings". Changing the region setting will require a reboot.


After making the change described above a Cortana app should be available in the standard app launcher. It can also be accessed by pressing the standard search button.  If the Cortana app does not appear, check the settings described above, and then reboot the phone again.

The first time you run Cortana you will be walked through a set up process. Additional options are configured via Cortana's notebook functionality.


If you change the language and/or region settings Cortana will no longer be accessible. Pressing the search button will revert to showing the standard Bing app (albieit with a new "phone" pivot page for searching for content stored on the phone).

While Cortana is a nice feature, it's probably not worth the hassle involved in having the "incorrect" region / language settings in day to day use. That's partly because much of the utility of Cortana is around location or region specific data, but also because the voice recognition aspect of Cortana is optimised for US accents (in its current form it doesn't seem to like the Queen's English - for shame).

Cortana is also relatively immature, which is only to be expected fora preview beta release. A key feature of Cortana is that it learns over time on both the personal level (i.e. about you), but also more generally. The second of these is actually more important because it means Cortana will get smarter over time for everyone, something that will also be augmented by Microsoft's fine tuning the underlying data sets / knowledge graph.
