IEEE P269

Revision Standard - Active - Draft.
This standard contains practical methods for making laboratory electroacoustic measurements of analog and digital speech communications terminals and connected audio devices. The methods are applicable to a wide variety of wired, wireless, cordless, and mobile communication terminals for indoor or outdoor use. Examples include Voice over Internet Protocol (VoIP), wireless LAN (IEEE 802.11), and softphone devices. Tests applicable to connected audio devices such as wired, low-power wireless (IEEE 802.15), and universal serial bus (USB) handsets, headsets, and wearables are included. The standard contains objective metrics, subjective metrics, and subjective metric predictors. Application is in the frequency range from 20 Hz to 20 kHz.

This standard provides methods for evaluation of electroacoustic devices that enable speech communication. These devices include handsets, headsets, and speakerphones, or incorporate microphones and speakers to provide a speech communication function. The standard is applicable to speech communication terminals that connect to any network, as well as to electroacoustic subsystems that connect to a terminal by any means. Due to the various characteristics of terminals and subsystems and the environments in which they operate, not all of the test procedures in this standard are applicable to all types of devices. Guidance for the applicability of specific tests is given within this standard. This standard does not apply to voice recognition systems such as speech-to-text, text-to-speech, or speech-to-command functions.
The purpose of this standard is to provide reproducible laboratory test methods for evaluating the electroacoustic performance of speech communication devices.
