184.108.40.206 ASR Data
Automatic speech recognition (ASR) data<2> refers to the text transcription of an audio attachment. In an unprotected voice message, this data is stored in the PidNameAutomaticSpeechRecognitionData property (section 220.127.116.11). In a protected voice message, it is handled as an attachment instead. As with other attachments in a rights-managed e-mail message, the attachment is stored in the Attachment List storage of the encrypted binary large object (BLOB), as specified in [MS-OXORMMS] section 18.104.22.168.1.
A client or server can submit a voice message to a third party transcription service in order to obtain a translation of the original message in the ASR data format. The transmission of data to and from this third party service is outside the scope of this specification.
