Applicable to the generic transmission characteristics, performance and testing principles of Speech Processing Devices for Acoustic enhancement (SPDA) intended for use in terminals, whatever the applications. Defines a framework for specifying performance constraints for terminals which include SPDA, and when appropriate, to define tests that may be performed on such terminals to verify that these constraints are met. Covers generic characteristics that are applicable to both analogue and digital terminals.
