Combining a low power voice trigger, multi-channel beamforming and
accessory detection to produce breakthrough improvement in performance

London UK, 18 September 2014 - Dialog Semiconductor plc (FWB: DLG), a
provider of highly integrated power management, AC/DC, solid-state lighting
and Bluetooth Smart wireless technology, today announced the availability
of two new audio DSP CODECs - DA7322 and DA7323 - targeting applications
with up to four analogue or digital microphones respectively.

Featuring the highest levels of audio digital signal processor (DSP)
functionality with a minimum power consumption requirement, these products
are specifically developed for voice-centric applications found in the
latest generation of tablets, wearables, webcam accessories and in-vehicle
entertainment.

The new audio CODECs incorporate an integrated 24-bit DSP with an advanced
voice engine package that provides an improvement of over 35dB
signal-to-noise ratio (SNR) through the use of multi-channel beamforming,
noise suppression and acoustic echo cancellation features. The result is a
significant enhancement in speech performance with greatly improved sound
quality for VoIP and voice recognition applications, which is particularly
important for end users in a noisy environment.

"There is an increasing need to improve the audio quality of voice calls,"
said Udo Kratz, Senior Vice President and General Manager, Business Group
Mobile Systems at Dialog. "Independent of the ambient noise conditions the
consumer is experiencing, both audio CODECs deliver a superior audio
experience by significantly reducing unwanted noise while maintaining voice
quality during VOIP calls on applications such as SkypeTM or LyncTM."

Targeting wearables, a low power voice trigger is available on the DA7322
and DA7323 where over a dozen keywords can be supported with over 95%
accuracy without false triggering. This capability is demonstrated by the
TrulyHandsfree(TM) always-on voice activation and recognition software
provided by Sensory, which includes trigger to search, user-defined
triggers, speaker verification and identification and multiple language
support.

Beamforming technology built into the DA7322 and DA7323 voice engine
package has been designed to offer maximum flexibility in terms of
