In-depth integration, performance tuning, and testing across voice, wireless, and distributed audio — backed by world-class chambers, proprietary automation, and real-world test homes.
Request a QuoteDeep Expertise in Modern Audio Systems
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.
