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.

65+ voice options
18 neural TTS languages
SSML support

Voice Biometrics

Secure Voice Authentication

Identify and authenticate users by their unique voice characteristics. Provide secure, frictionless access without passwords or PINs.

Speaker authentication
Speaker identification
Anti-spoofing protection
Fast enrollment

Audio Enhancement

Crystal Clear Audio Processing

Advanced signal processing to remove noise, echo, and reverberation. Ensure optimal audio quality in any environment for better recognition accuracy.

Noise suppression
Echo cancellation
Beamforming
Gain control

Voice-Text-Input

Free-Form Speech Recognition

Transcribes continuous speech into text with high accuracy. Ideal for documentation, reporting, note-taking, and long-form voice input.

Continuous recognition
High recognition accuracy
Custom vocabulary
Real-time transcription
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.

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.

The Components of the Next-Generation Voice AI Platform

Complete Suite for Scalable Voice AI Projects

From management to deployment, everything you need to build and scale voice-enabled solutions

Management Platform

VDK Console

Centralizes project access, role management, and technology assignment within a single collaborative hub. Work from anywhere on any device without local installations or version updates.

  • Full visibility and control across all projects and teams
  • Multi-project and multi-user environment support
  • Real-time access to the latest tools and dashboards
Development Platform

Build, Integrate & Accelerate

VDK Studio

Web-based development environment, always up to date. Design, configure, and test offline voice applications with AI-assisted voice command generation and real-time validation.

  • Browser-based access
  • AI Command Builder
  • One-click translation
  • Batch Unit Testing

VDK Developer Toolbox

Pre-configured samples, templates, and utilities that simplify setup. Includes package management, sample code, and detailed guides.

  • Code templates
  • Package management
  • Guided documentation

VDK API

Cloud-based solution enabling dynamic management of voice commands across all deployments. Create and update commands instantly without manual file handling.

  • Dynamic command management
  • No manual files
  • Cloud-based
Runtime Platform

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.

Architecture
  • 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
Execution
  • 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
Deployment
  • Cross-platform support across Windows, Linux, and Android
  • Embeddable runtime for on-device deployment
  • Reliable offline performance in low-connectivity environments
