Typical Applications

The IA611-RDI-01 reference design is ideal to facilitate adding a

voice enabled VUI or event detection into IoT products such as

home sensors, appliances, lifestyle control devices and security

systems.

Lighting Control: Controlling a light-bulb or smart electrical

controls with voice. Ultra low power consumption allows voice

control to fit into a small form factor.

Security System: Activating with a voice command or after

detecting an acoustic event (like glass breakage, smoke-alarm, or

a dog bark). Additionally, algorithms can detect anomalies in

sound, log direction of a noise source. A sensor with such audio

processing can then trigger an alarm or sent metadata to a hub for

logging and additional processing.

Remote Control: Controlling a TV using voice via a remote control

is a viable option and can include typical commands like - Turn

on/off TV power, change channel and navigate TV menu.

3rd-Party Algorithm Support

The IA611 is by nature an open DSP platform supporting up to

40MHz, 32-bit floating-point DSP. In addition to Knowles VoiceQ

voice wake/command, it can support 3rd-party audio/voice

algorithms such as Sensory voice wake/command, Audio Analytic

sound event detection. The Knowles Open DSP partner program

brings world-class algorithm partners to an ecosystem where a

multitude of solutions solve complex audio/voice problem. 3rd-

party algorithm support will continue to expand.
