Voice Activity Detection IP, WhisperTriggerTM
on <10µA Budget
Discover our Voice Activity Detection IP, WhisperTriggerTM
Ultimate Power Saving
The WhisperTriggerTM is a stand-alone feature. it enables to switching off the audio DSP and ADC, to divide the power consumption by up to 50 times compared to conventional approaches at a system level
Self-adaptability
WhisperTriggerTM‘s self-adjustable algorithm ensures the best detection rate whatever the environmental conditions of the user
An objective benchmark
Dolphin Design has developed MIWOKTM, a public benchmark solution to compare voice detection performances
High-performances
WhisperTriggerTM‘s outstanding performance – up to 100% detection rate both near field and far field conditions. Available in Analog and Digital
Innovation Voice Activity Detection for ultimate power savings
Conventional Always-On Keyword Spotting can not be ultra-low power
To minimize power consumption of a voice-controlled device, the current approach is to handle speech recognition after Keyword Spotting. It involves keeping the voice ADC and the DSP always on.
Dolphin Design solution, WhisperTriggerTM: Breakthrough Voice Activity Detection for ultimate power saving
Self-adaptable algorithm (patent-pending): the must-have
Users of wireless smart home, IoT products, or Smartphones are exposed to different types of ambient noises all along the day. As a result, the only solution to ensure the best detection rate is to rely on a trigger capable of continuously adapting itself to the environment of the device user.
WhisperTriggerTM‘s powerful algorithm wakes up the DSP handling Keyword Spotting with the best success rate, no matter the environment of the user and the distance between the user and the voice-activated device.
MIWOKTM, an objective benchmark for Voice Activity Detection
Dolphin Design has developed MIWOKTM, the first public domain benchmark for voice activity detection. It characterizes the performance in different conditions and environments. You can benchmark:
- the detection latency (DL)
- the radio of voice detected as voice (VDV)
- the radio of noise detected as voice (NDV)
The WhisperTriggerTM's performances
Our VAD was designed to support and optimize power consumption of your keyword spotting solutions.
To ensure to not impact the performances of your keyword spotting algorithm, our VAD can detect all phonem before 60% of its duration( average of 16%).

More than ever before, attention to power consumption is paramount when developing new products. In this environment, voice activity detection has a major role to play in any new voice-controlled system. The main objective of VAD is to lower power consumption, saving on computation or data processing by deactivating part of the SoC when no speech patterns are detected.
Markets like home assistants and telecommunications can greatly benefit from this feature as the
always-on mode is not exactly suitable for wireless products or when privacy is a concern.
