We provide in-depth capabilities for the integration, performance tuning, and testing of a wide range of audio technologies. Our engineers have domain expertise around the myriad of ways audio is implemented today, from voice-enabled devices and distributed home audio to embedded mixed-signal systems.
Our facilities meet the highest standards for a controlled environment, with the ability to introduce outside physical and RF variables on demand. Alongside industry-standard instrumentation, we've developed proprietary software tools that capture KPIs, true user experience, and competitive analysis at a depth no other approach delivers.

Voice Validation Across Every Engine
The AVVF is a Novus Labs-developed test framework that measures the performance of voice-controlled devices regardless of which ASR engine, cloud service, or platform sits behind them. Whether your device runs Alexa, Google Assistant, Siri, or a proprietary engine, the AVVF measures what your end user actually experiences, with the same acoustic rigor as the rest of our audio program, focused on speech recognition accuracy, latency, and behavior under real environmental noise.
- Cloud-service agnostic: works with any ASR engine or backend
- Near-field and far-field test scenarios
- Adaptive learning algorithm for end-to-end tests
- Custom utterance generation via Speechify, Murf AI, and other TTS tools
- Multiple environmental noise conditions (silence, pink, party, music, crowd)
Beyond the Chamber
Controlled labs get you most of the way. Real-world environments close the gap.
Residential Test Homes
Our dedicated residential test homes provide authentic environments for validating audio products at scale: real walls, real Wi-Fi, real interference. Essential for distributed home audio and smart speaker programs.

Case Study: Wireless Interference
A prominent headphone manufacturer couldn't figure out why audio cut out when the paired phone sat in a user's back pocket. Novus built a gel-body dummy and mapped the interference across real-world congestion scenarios.
