The mobile voice calling use case has evolved significantly over the past years. Consumers expect high-quality voice communication in all situations: In house, in a busy street and in the car. The adoption of hands free voice calling has increased because people use their mobile as a speakerphone, in the office or even outdoors. In addition, consumers familiarize themselves with the increased clarity offered by VoIP solutions such as Skype. 

Mobile Network Operators follow this demand for increasing voice call quality. For example, many 3G operators in Europe have started upgrading their networks to support HD Voice and some other operators have focused on stricter noise suppression requirements than before. These operators clearly consider enhanced voice quality as a key differentiating feature of their networks and mobile devices. LifeVibes VoiceExperience was exactly designed for that. 

LifeVibes VoiceExperience

LifeVibes VoiceExperience provides state-of-the-art voice calling enhancements for mobile devices such as smartphones, feature phones and tablets. VoiceExperience includes two microphone noise suppression and acoustic echo cancellation that allows device manufacturers to deliver voice quality that exceeds mobile operator requirements. This solution enables consumers to make phone calls under normal and noisy conditions, both in handheld and speakerphone mode. LifeVibes VoiceExperience today runs on almost a billion mobile devices and is used by major mobile device manufacturers on flagship devices to enhance circuit-switched, VoIP and VoLTE calls. It is a platform-independent full-software solution, allowing device manufacturers to achieve consistent voice call quality across different vendors’ hardware platforms such as baseband modems, application processors, SoCs and audio codecs. The solution has also been integrated in Android and Windows Phone devices.
