Security systems are becoming more valuable with the addition of voice and facial recognition features. Real-time recognition requires embedded systems with very high computational capabilities and on-chip hardware acceleration. Renesas' voice and facial recognition solutions can provide secure access to individuals based on biometric feedback.

Voice User Interface (VUI) Technology

The worldwide market demand for voice recognition is growing very fast. Especially, smart speakers and smart phones are fueling VUI growth in all areas. Rapid adoption of the IoT and the COVID-19 pandemic is further accelerating and driving voice-based technology adoption globally.

The voice segment is roughly separate into two. One is Speech Recognition the other is Conversational AI.

  • Speech Recognition: focuses on understanding few words. Applications such as home appliances, portable and industrial applications. IoT endpoint requiring small resources. Ecosystem is evolving.
  • Conversational AI: focuses on human-like conversation. Applications are smart speakers and smartphones and similar products, and IoT gateway to connect to the cloud. Requires more powerful MPU and resources. Ecosystem is mature.
