LifeVibes VoiceExperience Delivers Quality According to Listening Tests at MWC2013!
EINDHOVEN, The Netherlands, March 19, 2013 /PRNewswire/ –
This year’s NXP Software booth at Mobile World Congress 2013 was almost entirely
devoted to voice enhancements i.e. features like noise suppression and echo cancellation
required to enhance the quality of voice calls. Visitors participated in multiple
interactive demos to hear how LifeVibes VoiceExperience delivers increased quality and
clarity for wideband audio (HD Voice). Offering best-in-class noise suppression and echo
cancellation, LifeVibes VoiceExperience provides a premium consumer experience across all
platforms and ecosystems.
One of the demos was a simple A-B pairwise listening test, in which several competing
2-microphone noise suppression solutions are compared.
The items in the listening test are recordings made from commercially available
solutions. The phones under test are the Huawei Ascend D1, the Sony Xperia T, the Apple
iPhone5 and two different tunings of LifeVibes VoiceExperience. The listening test is
blind, i.e. the booth visitor is presented two audio clips without disclosing to which
phone they correspond. Two different noise conditions have been used: babble noise, which
contains both stationary and non-stationary components and a music track which is highly
non-stationary. The noise is played at two different levels. After having played audio
clip A and B, the question for the visitor to answer is simple: “Which one do you prefer?”
After four days of testing at Mobile World Congress, 613 votes have been cast. From
these votes, 82 times a visitor indicated “equal”. Of the remaining 531 votes, the
preference for LifeVibes VoiceExperience was clear.
New voice blog!
NXP Software’s noise suppression demonstration gave everyone a chance to hear how
noise can be removed while still maintaining quality of speech. This ensures
intelligibility in noisy environments such as railway stations or restaurants, including
when using speaker mode. NXP Software’s voice experts have been developing voice
enhancement algorithms for almost a decade now. The recently launched VoiceGurus.com blog
will report and comment on interesting activities related to aspects of voice technology
for mobile devices.
“We have a lot of technical expertise to share on voice technology for mobile
devices,” says Ralf Funken, Product Manager Voice at NXP Software. “The VoiceGurus blog
will look at the technical challenges of delivering a high quality voice experience on
mobile devices. We will share our insights and opinions and want everyone to get involved
in the discussion.” http://www.voicegurus.com
