Alcatel-Lucent Contributes Voice Quality Algorithm to ATIS Standard

The American National Standards Institute (ANSI) has approved a new voice quality monitoring standard based on Alcatel-Lucent algorithm. This new ATIS standard (ANSI ATIS 0100005-2006) addresses the challenge of how to implement a non- intrusive speech quality test that can be done in live networks in real time without requiring human listeners and that will not interrupt actual calls.



Alcatel-Lucent's ANIQUE+ (Auditory Non-Intrusive QUality Estimation Plus), which is machine based, overcomes the challenges present in today's subjective approaches to monitoring speech quality where people are used to evaluate speech quality of telephone networks and codecs by listening to audio signals and using tools such as the Mean Opinion Score (MOS) to define the network's audio quality. Subjective measurements of this sort are not viable for today's real-time, heterogeneous networks due to costs and scalability.
