Developed in-house and leveraging CEVA’s vast expertize in audio and voice processing, ClearVox incorporates advanced algorithms that cope with different acoustic scenarios and microphone configurations, including optimized software for speaker direction of arrival, multi-mic beamforming, noise suppression and acoustic echo cancellation, as well as the related firmware and driver software. CEVA’s WhisPro operates in tandem with ClearVox and offers customers like Novatek a robust CEVA DSP-based speech recognition solution for always-listening devices such as smart TVs, smart speakers, smartphones and Bluetooth® earbuds to interact with cloud-based voice assistant services. This holistic integration of voice pre-processing and neural network algorithms delivers a high recognition rate even in noisy environments and in far field use-cases, while operating locally on the edge device, thereby maintaining user privacy and providing minimal latency. CEVA’s ClearVox and WhisPro are optimized for the CEVA-X2 high performance audio/voice DSP designed for intensive audio applications in smart home, mobile, and automotive markets. The CEVA-X2 DSP is using 5-way VLIW micro-architecture and is offering parallel processing with dual scalar compute engines, support for Single Instruction Multiple Data (SIMD), as well as optional floating point units for high accuracy algorithms.
