Six Powerful Voice AI Technologies

Build sophisticated voice experiences with our comprehensive technology suite.

Voice Commands

Intelligent Voice Control

In-app navigation and task execution through voice. Enables frontline workers and caregivers to complete actions faster with less physical interaction, significantly boosting productivity.

Multi-language support
Offline processing
Context-aware responses

Wake Word Detection

Always Listening, Always Ready

Activate the voice interface with custom wake words. Low-power, passive, always-on detection ensures instant response while preserving device battery life. Supports anti-wake words to prevent accidental activations, ensuring the system only wakes up when truly intended.

Custom wake word training
Low power consumption
High accuracy detection
Anti-wake word filtering

Voice Synthesis (TTS)

Natural, Human-Like Speech

Delivers clear, adaptive voice instructions for frontline workers and caregivers. Supports speed adjustments for efficiency, volume boosts for clarity, and optimal playback for varied operational environments.

Voice Error Correction

High-Accuracy Voice for Real-World Environments

Vivoka makes voice recognition accurate and reliable in the real world — even where traditional ASR fails

ASR Alone Struggles

🔇 Noise limits accuracy
🗣️ Accents create recognition errors
Fast or natural speech breaks the pipeline
⚠️ Real operational use cases become unreliable

Vivoka Unlocks Accuracy

🎯 Cleans noise intelligently through advanced audio processing
🌍 Adapts to any accent with a lightweight Transformer correction model
💬 Handles fast speech and imperfect pronunciation
📊 Boosts accuracy with context lists that guide correction toward valid sequences
⚙️ Supports very large context lists with no impact on performance

The Impact

77%
Fewer Errors*
*Internal benchmark on real-world alphanumeric use cases
Faster workflows and smoother task execution
Fewer operator mistakes, even in noisy or multilingual environments
🚀 Broader real-world use cases thanks to higher accuracy and reliability
💎

Innovation Included

VEC technology is part of the Logistics Performance Pack, supporting alphanumeric sequences (1–7 characters) with ultra-low latency (<10 ms) and running directly inside the ASR pipeline with no additional dependencies.

⚡ Ready to deploy
🏅

Industry Standard

Aligned with Gartner's 2025 WMS Critical Capabilities, where usability and voice accuracy are essential in retail & e-commerce fulfillment. VEC delivers the precision required for modern warehouse operations.
