The GSM Association (GSMA) has now specified test methods to assess the minimum performance requirements for allowing manufacturers of LTE mobile terminals and network providers to make use of the HD Voice+ (High Definition Voice+) logo. Combining HEAD acoustics' advanced communication quality analysis system ACQUA with the measurement front end MFE VIII.1, plus codecs and software options, manufacturers will be able to test their systems for the new Voice+ certification.

Speech and audio quality specialists, HEAD acoustics GmbH from Herzogenrath, Germany, will be presenting its range of solutions at the Mobile World Congress (​​February 27 to March 2, 2017). Like many key development technology companies, HEAD acoustics will use the Barcelona show to demonstrate a new evaluation software of VoCAS (Voice Control Analysis System), as well as an update of its communication analysis software ACQUA 3.5.100.
