AMPING UP THE QUALITY C
EVA and Novatek have worked together on the deployment of TV
system-on-chips (SoC), licensing and integrating CEVA’s X2 Audio DSP, ClearVox voice front-end software and WhisPro speech recognition software, together, into the system’s technology: it is intended to guarantee always-on, far-field voice wakeup and control functionality, as part of the SoC’s multi-microphone enabled makeup. “We are excited to expand our
partnership with Novatek and bring the power of the voice user interface to their smart TV SoCs,” said Moshe Sheier, vice president of Marketing at CEVA: “Our CEVA-X2 DSP, together with our ClearVox and WhisPro voice software packages, allow Novatek to add new features that create a unique and tailored multilingual voice entertainment experience for their customers.”
Developed in-house, and leveraging CEVA’s history in audio and voice processing, ClearVox utilises advanced algorithms tailored to a variety of acoustic scenarios and microphone configurations, including optimised 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 parallel with ClearVox, providing customers like Novatek with a CEVA DSP-based speech recognition solution for cognitive devices such as the aforementioned 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 is capable of functioning in
spite of invasive noise: it offers a high recognition rate, even in far field use- cases, while operating locally on the edge device, maintaining user privacy and providing minimal latency. In this regard, CEVA’s ClearVox and WhisPro are optimised for the CEVA-X2 high performance audio/voice DSP, and are designed for integration in audio applications, in the 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.
