ANSI Standard for Voice Biometrics

An item on SpeechTechMag.com indicates that "the American National Standards Institute has published INCITS 456: Speaker Recognition Format for Raw Data Interchange (SIVR-1), a standard governing the type and format of data that should be included with shared audio files used for speaker identification and verification." Judith Markowitz, president of J. Markowitz Consultants is the editor of the standard, which was 4 years in the making.

The types of data to be included with the file are: the bandwidth used to make the recording; date and time of the recording; type of channel that was used to record the data, such as a wireless or landline phone; information about the speaker, such as gender, age, language, and accent; the input device used; security used, such as the type of encryption; and the sampling rate. According to the article, the format is intended to be vendor-neutral.

It should be noted that, although the standard is not mandatory, it can be very useful to organizations such as military, intelligence and law enforcement that often share data about potential threats.
