Application Brief - Always on AI: True Wireless Stereo Headphones

Always-on Key Word Detection, Environment Classification and Voice UI for True Wireless Stereo Headphones

Adding trigger keyword detection (KWD), simple commands (like volume up/down, next, skip, shuffle) and detecting and classifying the ambient environment for dynamic noise cancelling in-ear pods are all high-value-added features. However, adding these features in space-constrained and power-limited true wireless stereo headphones presents a significant engineering challenge. Ultra-low power, small size and low latency are required in a cost-effective solution; all analog AI compute from Blumind is an ideal solution. Blumind is the leader in all analog edge AI with its AMPL™ technology.
