Bring Cloud-Standard Voice AI to Microcontrollers.

Cloud-standard voice features — now offline on MCU: ASR, TTS, and Small LM.

ASR (Automatic Speech Recognition) — IP block

  • Available: English.
  • Customization: new languages, domain-specific vocabularies, constrained grammars.

TTS (Text-to-Speech) —
 IP block

  • Available: English.
  • Customization: new languages, custom voices (tone, style, brand identity).

Small LM (Lightweight Language Models)

  • Ready IP: TinyStories (EN) — pre-trained, fully offline storytelling.
  • Custom Small LMs — tailored for intents, Q&A, dialogs, or new languages.

Customization Options

  • Add new languages and domain vocabularies.
  • Design voice flows with clarifications and confirmations.
  • Create custom TTS voices.
  • Optimize for RAM, Flash, and latency on your platform.

Platforms We Support

  • ESP32 (incl. ESP32-S3) → fast PoC and cost-sensitive devices.
  • Arm® Cortex™-M + Arm® Ethos™-U55 / other AI SoCs → high performance, energy-efficient production.
  • Migration path: start on ESP32 → scale to Arm® Ethos™-U55.

Applications

  Smart appliances

natural dialogs instead of rigid commands:
“Start cooking.” → “For how many minutes?” → TTS: “Cooking started, 10 minutes remaining.”

Toys & EdTech

interactive learning and safe offline storytelling (AI Teacher, TinyStories).

Access control 

ASR turned into offline numeric PIN (VoicePIN).

OEM Benefits

  • Faster time-to-market — PoC in weeks, not months.
  • Lower OPEX — no recurring cloud costs, fewer complaints.
  •  Minimal BOM increase  — add offline voice with negligible hardware cost.
  •  Pro SKU differentiation  — premium devices with offline voice features.
  •  De-risked adoption  — tested by the DIY community before reaching OEM scale.

DIY Proof (Social Proof)

our DIY product with three apps showing how one ASR + Intent stack enables multiple use cases:

For OEMs, the VoxControl Kit is proof that one stack can power very different devices — from toys to appliances to security systems.

How We Work

Evaluate
Pilot (PoC)
License & Integrate
  1. Evaluate — define target sounds, access scenarios, hardware.
  2. PoC — 2–3 weeks, fixed scope, measurable detection rates and latency.
  3. License & Integrate — adapt IP for your product; PoC fee credited to license.

Deliverables

  • ASR & TTS (EN) IP binaries, APIs, integration guides.
  • TinyStories (EN) ready-to-use IP.
  • Optional: custom Small LMs, language packs, TTS voices.
  • Metrics pack (latency, energy, memory).
  • Demo video on your device.

Licensing

  • PoC license — quick validation.
  • Project license — tuned models, integration support.
  •  Volume license — mass deployment.
No lock-in: portable IP, stable APIs, integration code stays with OEM.
