VoiceSpot is a high-performance embedded wake word and small vocabulary ASR engine, enabling voice-wake and command and control on memory-constrained, battery-operated edge devices. VoiceSpot achieves high performance levels with very small 30 to 35KB typical model size (depending upon the specific wake-word), with a total memory footprint of under 80KB. CEVA’s audio/voice DSPs are widely deployed in battery-operated edge devices for voice activation and control, including TWS earbuds, smartwatches, action cameras and smart home appliances. These DSPs are ideal for hosting wake word engines like VoiceSpot at extremely low power standby, while also being able to run complex voice front-end algorithms such as echo cancellation and beamforming to improve voice intelligibility and pickup quality.
