Key Features of soundKIT

01

Audio Edge AI

Develop always-on key AI audio features, including speech enhancement (denoising and dereverberation), keyword spotting, voice activity detection, and speaker/voice authentication, on edge devices.

02

Task-Level Modes

Use s a consistent CLI across the full audio AI workflow: dataset setup, model training, benchmarking, validation, deployment, and real-time inference demos on PC or Ambiq EVBs.

03

Flexible Iteration

Swap datasets, models, tasks, and training recipes using YAML configurations, CLI commands, or Python APIs, without changing the core workflow.

04

Power and Performance

Powered by heliaRT™ for production-grade deployment on Apollo SoCs, delivering up to 3× faster inference than TFLM with vector-accelerated AI kernels, and enhanced int16x8 quantization for high-fidelity audio and speech

Tasks & Capabilities

Speech Enhancement (SE)

On-device speech enhancement with denoising and dereverberation to improve speech clarity in noisy, real-world environments.

Keyword Spotting (KWS)

Fast, low-memory wake-word detection using lightweight models compatible with TensorFlow Lite and TensorFlow Lite Micro (TFLite/TFLM).

Voice Activity Detection (VAD)

Real-time, low-power detection of speech presence to reduce false triggers and extend battery life in always-on audio systems.

Speaker Verification (ID)

Secure, privacy-preserving on-device speaker verification for voice authentication—no cloud connectivity required.

soundKIT is optimized for smart speakers, wearables, IoT devices, industrial systems, smart home products, and other battery-powered edge AI devices.
Keyword spotting enables devices to detect specific wake words or voice commands locally on-device with ultra-low power consumption.
Yes. soundKIT includes speech enhancement capabilities that improve voice clarity and reduce background noise in challenging environments.
Voice Activity Detection identifies when human speech is present, helping optimize audio processing efficiency and power consumption.
Yes. soundKIT is designed for on-device edge AI inference without relying on cloud processing.
By processing audio locally on-device, soundKIT reduces the need to send sensitive voice data to external cloud servers.
soundKIT is optimized for Ambiq SPOT-based SoCs with on-going updates to support future releases.
Smart home, healthcare, industrial IoT, wearables, consumer electronics, and voice-enabled device manufacturers all benefit from soundKIT’s edge AI audio capabilities.
soundKIT leverages Ambiq’s ultra-low power architecture and optimized edge AI workflows to enable always-on audio processing with minimal energy usage.
Yes. soundKIT supports on-device speaker verification and voice identity recognition for secure and personalized experiences.
Edge AI enables faster response times, improved privacy, lower latency, and reduced power consumption by processing audio directly on-device.
No. soundKIT supports offline on-device audio AI inference without requiring continuous cloud connectivity.
No. soundKIT is built exclusively for Ambiq SPOT-based SoCs, and that focus is what makes it powerful. Tight hardware-software integration enables real-time audio processing, always-on speech enhancement, and ultra-low power efficiency that no general-purpose platform can match.
