Smarter LLM Agents, Better Voice Experiences

LLM-powered voice assistants are only as good as their front end: activation, transcription, and conversation flow must feel instant and seamless, or users drop off. Sensory’s embedded AI technology stack provides low-power wake words, on-device speech-to-text, and lightweight language models that act as a smart gateway between users and your LLM.​

With Sensory Micro Wake Words, Word Spotted Commands, Custom Grammar, Speech-to-Text, and on-device Micro and Small Language Models, product teams can build voice experiences where the user’s audio stays local and only the clear, intent-ready text or structured requests reach the LLM. Hybrid options and external LLMs let you route each part of the workload (wake word, verification, STT, NLU, and generative responses) to the edge or cloud for the best mix of privacy, cost, and performance.​

Key Features for LLM Voice Agents

On-device AI that makes LLM voice experiences faster, cheaper, and more private.

1

Award-Winning Speech Gateway

On-device STT acts as a high-accuracy gateway to LLMs, cutting cost and latency while keeping voice data local.​

2

Embedded-First Architecture

Wake word, STT, NLU, and biometrics run at the edge, so assistants still wake, listen, and respond even when networks are weak or offline.​

3

Real-World Robustness

Models are tuned for far-field noise, accents, and everyday environments, reducing false wakes and missed triggers.​

4

Faster Design with VoiceHub

VoiceHub’s generative AI tools help design intents and grammars in hours instead of weeks.​

5

Proven at Scale

Wake words, STT, and biometrics ship in over two billion products, hardening the LLM voice stack.​

Why LLM Voice Teams Choose Sensory

An embedded AI foundation built for LLM-era assistants.

Lower LLM Costs

On-device STT filters and compresses what reaches the model.​

Better UX

Low-latency wake, listen, and response flows.

Privacy by Design

Raw audio and biometrics can stay on device.​

Works When Offline

Assistants remain useful with limited connectivity.​

Built for Scale

Trusted across billions of consumer and enterprise devices.

LLM Voice Agent Use Cases

Sensory powers LLM-based voice experiences across consumer, automotive, enterprise, and healthcare applications.​

  • Voice chat on devices– Speak naturally with LLMs across TVs, wearables, and phones.
  • Automotive copilots– In-cabin agents that handle routes and vehicle controls privately.
  • Enterprise Assistants– Meeting and desktop agents that pre-process audio locally before corporate LLMs.
  • Customer Service– Kiosks and IVRs capturing intent accurately before LLM-driven dialogue.
  • Healthcare and regulated– On device capture with only de-identified or structured text sent upstream.

Frequently Asked Questions

Everything you need to know about Sensory for LLM voice agents

Yes. Without a wake word, LLM voice agents risk continuous listening, higher compute costs, and unclear activation boundaries; Sensory’s on-device wake words give users explicit control while improving privacy and power efficiency.​

On-device STT transcribes speech locally in milliseconds, then sends only clean text to the LLM, cutting round-trip latency, shrinking cloud bills, and ensuring the user’s voice never leaves the device.​

Yes. Sensory’s role is to handle wake word, STT, NLU, and optional biometrics at the edge, then hand off text and metadata to your chosen cloud or on-device LLM via your existing APIs and infrastructure.​

Sensory supports a wide range of CPUs, NPUs, and microcontrollers across mobile, PC, TV, automotive, embedded Linux, and RTOS-class devices, from high-end SoCs down to constrained edge hardware.​

VoiceHub lets developers design and train wake words, commands, and grammars to quickly create high-quality front ends for LLM-powered voice agents.
