Choosing the Right Audio Front End

Number of Mics

How you want your users to interact with your product determines the number of microphones you select. Voice-enabled devices designed for closer, hands-free interaction can use 1 or 2-mic solutions, whereas far-field products with listening ranges from across the room can benefit from a 4 or 7-mic array. Keep in mind that additional mics may take up more physical space and add incremental costs to your product.

Mic Arrangement

Your product’s form factor determines the arrangement of microphones. Square or circular arrays in a horizontal plane are better for 360-degree, omni-directional listening often utilized in tabletop products like the Amazon Echo or Echo Dot. Linear arrays are better suited for uni-directional listening or wall-mounted products such as connected light switches and thermostats with Alexa built-in like the ecobee4.

Audio Algorithms

Voice processing algorithms enable your device to leverage the full capabilities of the mic array. Noise reduction improves speech recognition in noisy environments, beam forming helps locate the direction of speech, and acoustic echo cancellation allows the user to barge in even when your device is playing loud music. These algorithms, combined with wake word engines, allow voice-initiated interactions and send clear, processed audio to the cloud.
