Neural network-based speech recognition technology for voice assistants and IoT devices
WhisPro™ is an AVS qualified neural network based keyword spotting (KWS) software package, allowing customers to add wake-words and commands to voice-enabled IoT devices. As a voice user interface, WhisPro is targeting the rapidly growing use of voice as a primary human interface for intelligent cloud-based services and edge devices.
WhisPro provides a customizable (any language, any keyword) wake-word and keyword voice interface. This allows users of headsets, wearables, smart TVs, smart speakers, smartphones , infotainment systems, and other voice-enabled IoT devices to interact with cloud-based voice assistant services, as well as enabling voice activation on edge devices through its small footprint and processing needs, without cloud connectivity.
Benefits
WhisPro voice user interface enables wake words and commands for always listening devices
High recognition rate with very low false acceptance rate operating on-device
Scalable RNN speech AI technology supports simultaneous multi wake-word phrases
Built-in ambient noise cancellation engine for improved user experience in noisy environments
