Offline Voice AI
for Professional Applications
The complete suite for scalable Voice AI projects, offering a full development platform with Console, Studio, Developer Toolbox, and Runtime components. Build custom voice-enabled solutions and voice-guided workflows that work offline, on any hardware, with full control over your data and deployment.
Six Powerful Voice AI Technologies
Build sophisticated voice experiences with our comprehensive technology suite.
Voice Commands
In-app navigation and task execution through voice. Enables frontline workers and caregivers to complete actions faster with less physical interaction, significantly boosting productivity.
Wake Word Detection
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.
Voice Synthesis (TTS)
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 Biometrics
Identify and authenticate users by their unique voice characteristics. Provide secure, frictionless access without passwords or PINs.
Audio Enhancement
Advanced signal processing to remove noise, echo, and reverberation. Ensure optimal audio quality in any environment for better recognition accuracy.
Coming Soon
Voice-Text-Input technology demo will be available shortly.
Voice-Text-Input
Transcribes continuous speech into text with high accuracy. Ideal for documentation, reporting, note-taking, and long-form voice input.
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
Vivoka Unlocks Accuracy
The Impact
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.
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.
Voice Recognition User Words
Make speech recognition adapt to real people, real pronunciation, and real operational vocabulary by linking user-recorded audio samples to specific words or phrases.
Generic models miss what matters most
Better recognition where standard ASR struggles
Teach the system how your users actually say the words that matter.
Voice Recognition User Words lets applications capture a user saying anything and associate that audio with a target word or phrase. The result is a more personalized and accurate recognition experience for names, jargon, acronyms, and domain-specific vocabulary — without reworking your existing application logic.
Capture
Record a user-provided audio sample directly from the real speaker in the real context.
Associate
Link that sample to a target word or phrase such as a name, code, acronym, or business term.
Recognize
Improve recognition accuracy in live usage without retraining full models or rebuilding the app.
Ideal for
What you gain
Improve recognition quality for the words that matter most to your users, workflows, and business environment.

Built for real-time execution
Replace traditional request/response bottlenecks with a continuous streaming architecture. VDK Service is designed to handle high-throughput voice data with zero-latency overhead.
VDK Service
Real-time audio processing engine for building end-to-end voice workflows. Design modular pipelines where audio flows from input to processing to output through a structured sequence of Producer, Modifiers, and Consumers.
Each pipeline runs inside a session that manages execution and communication, allowing you to stream audio and receive results instantly. Replace multiple voice services with one cohesive system, deployable across Windows, Linux, and Android as an embeddable runtime, with reliable offline performance even in low-connectivity environments.
- Modular pipeline architecture with Producer, Modifiers, and Consumers
- Modifiers transform audio in real time, including enhancement and channel extraction
- Consumers deliver results such as transcription, audio output, storage, and biometrics
- Support for parallel outputs so audio is processed once and reused in multiple ways
- Real-time streaming via WebSocket for continuous input and output
- Session-based execution, configure first and run on demand
- REST API for lifecycle and configuration management
- Cross-platform support across Windows, Linux, and Android
- Embeddable runtime for on-device deployment
- Reliable offline performance in low-connectivity environments
