VoiceExperience 4.0 demos

To experience the sound and speech algorithms used by LifeVibes VoiceExperience we have prepared demonstrations of the latest VoiceExperience 4.0 software for device manufacturers and platform providers.

We demonstrate VoiceExperience on multiple platforms and compare the performance on multiple current commercial available smart devices. If you are interested in a demo please contact us via info.software@nxp.com.


Voice benchmark

Demo 1: Voice Benchmark

Benchmark the noise suppression quality from multiple commercially available 2-microphone smartphones, each with a different noise suppression algorithm. Listen and judge which solution provides the best noise suppression. At the end of this blind listening test, the results will be shown on screen.

LifeVibes VoiceExperience Benefits
