Voice User Interface

In today’s interconnected world, Voice User Interface (VUI) technology represents a transformative approach to human-computer interaction, offering intuitive and natural ways for users to engage with devices, applications, and services through voice commands and responses.

Voice User Interface technology enables users to interact with devices and applications using spoken commands and natural language, eliminating the need for traditional input methods such as keyboards or touchscreens. By leveraging the power of speech recognition, natural language processing, and machine learning, VUI systems can understand user intent, execute tasks, and provide personalized responses in real-time, revolutionizing the way we interact with technology.

How Dolphin Semiconductor Enables Low Power VUI?

µW Voice Activity Detection IP

Low power Voice Activity Detection (VAD) IP optimizes energy usage by activating processing modules selectively. Efficient algorithms adapt thresholds and sensitivity, minimizing false positives. Hardware implementation ensures energy-efficient operation, extending battery life and enhancing system performance in portable devices.

µW Audio Feature Extraction IP

A voice feature extraction hardware IP enhances audio processing efficiency by extracting key features from speech signals ( MFCC) by dividing by 1000 the power consumption. This optimized extraction process minimizes computational load, conserving power and resources. With efficient hardware implementation, our IP enables accurate MFCC while replacing the ADC, VAD and DSP, maximizing system performance in voice-based applications
