Ambiq Voice-on-SPOT (VoS) Kit

The new Ambiq Voice-on-SPOT (VoS) Kit from Ambiq is released to help manufacturers introduce voice-command into IoT devices with faster time-to-market. The VoS Kit brings voice and audio capability to battery-powered devices with Always-on-Voice (AoV) functionality.

This fourth-generation Voice-on-SPOT (VoS) Kit enables battery-powered endpoint devices to achieve a higher level of intelligence without compromising on battery life. The kit integrates Ambiq’s hardware and software with peripherals and third-party IP, including signal processing using DSP Concepts’ Audio Weaver, Sensory VoiceHub, and Retune DSP VoiceSpot.

Targeted applications include remote controls, gaming controllers, smart sensors, smartwatches, remote mics, and health trackers.  Built upon Ambiq’s proprietary Subthreshold Power-Optimized Technology (SPOT) platform, this device enables manufacturers to create edge endpoint devices with an easy-to-use, rich peripheral set. The VoS kit is built on the Apollo3 Blue plus MCU and supports Always-on-Voice with application and cloud service driven options for one or two mics, signal processing, wake word/command detection, codec, and Bluetooth LE (BLE) communication.

The device will lower always-on power with 2 analog mic inputs while increasing capabilities with up to 8 digital mic inputs, 120dB SNR (Signal to Noise Ratio) PDM (Pulse Density Modulation) to PCM (Pulse Code Modulation) converter, 192MHz Arm M4F MCU, highly precise clocking and advanced interconnectivity with hardware rate matching. The next generation Apollo4 Blue VoS Kit will be available in the third quarter of 2021.
