Change the default language for greetings and emails
Cloud Voicemail uses various language settings to play greetings, generate transcription translations, and generate voicemail messages. The language settings can be specified by default on the tenant level, by policy, or individually on a given user.
Greetings are played to the caller leaving voicemail and can be the following types:
- System greetings
- Custom greetings recorded by the user being called
- Custom text-to-speech greeting specified on the user being called
The language used to play the system greetings is, in priority order, either the primary and secondary prompt language specified in the online voicemail policy assigned to the user, the preferred language specified for the user, or the default tenant language.
The custom and out of office greeting are recorded by the user in the language chosen by the user.
If custom text-to-speech greetings are specified for the user either by the user or the tenant administrator, the language used to generate the speech is the PromptLanguage specified together with the text-to-speech greetings.
The custom text-to-speech greetings are only used if there are no custom greetings recorded for the user.
If enabled by the online voicemail policy for the user being called, Cloud Voicemail will try to transcribe the voicemail left by the caller. It will use speech detection to understand the language used in the audio content and, if possible, transcribe the content using the detected language.
If enabled by the online voicemail policy for the user being called, Cloud Voicemail will translate the transcribed voicemail. It will translate from the language detected during speech detection into, in priority order, either the preferred language specified for the user or the default tenant language.
Voicemail message template
Cloud Voicemail will generate the voicemail message using a language template based on, in priority order, either the preferred language specified for the user or the default tenant language.
Setting the preferred language for a user
You can set the preferred language for a user using PowerShell either in Microsoft Entra ID or in the on-premises Active Directory. For more information, see How to set language and region settings for Microsoft 365 or Office 365.
Users can change their own preferred language through their settings after they sign in. For more information, see Change your display language and time zone in Microsoft 365 for Business
