Cortana voice support

Cortana voice walks the user through the OOBE experience, enabling the user to complete parts of OOBE by responding to spoken prompts. Cortana voice during OOBE is currently available in the following languages: En-US, es-MX, ja-JP, en-GB, fr-FR, it-IT, de-DE, es-ES, fr-CA, en-CA, en-AU, pt-BR, zh-CN.

The language value you set in OOBE.xml impacts the voice used during OOBE. The OOBE.xml value for language must be a language/region decimal ID associated with a Windows language pack. For example, the English (United States) language pack has an associated language/region decimal ID of 1033. For a full list of language/region decimal IDs that you can set in OOBE.xml, see Available Language Packs for Windows.

Cortana voice is enabled after the customer selects a language from the Language selection screen in OOBE. If the language selected by the customer, combined with the language in OOBE.xml, is supported by Cortana, Cortana will assist in that language upon entering the Region selection page.

Cortana voice will continue to assist throughout the OOBE process in that same supported language. Even if the user selects a region on the Region page that is not supported by Cortana, or selects a region that would cause Cortana to use a different accent after OOBE, Cortana voice will not change during OOBE.

If the language selected by the customer on the Language page combined with the language in OOBE.xml is not one of the supported combinations for Cortana, then the OOBE experience will be silent.

After the user completes OOBE, the voice used in the Cortana app will be based on the Language and Region selected during OOBE. At that point, Cortana will no longer consider the language in OOBE.xml.

Here are a few examples:

Language selected by customer (during OOBE) Language set in OOBE.xml Region selected by customer (during OOBE) Cortana voice assistance result (during OOBE) Cortana app voice result (after OOBE)
English 1033 (en-US language pack) US en-US en-US
English 1033 (en-US language pack) US en-GB en-US
Russian 1049 (ru-RU language pack) US Silent Not supported

Disable Cortana voice support

For testing purposes, you can turn Cortana voice off, but you must enable it again before the device ships. To temporarily turn Cortana voice off, set the following registry key.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\OOBE : DisableVoice = 1 (DWORD)

Note

This setting should only be disabled for testing purposes. Shipping a device with Cortana voice support disabled is an unsupported configuration.
