Voice Quality Enhancement: Pure and Natural Voice Experience

Adaptive Digital offers Voice Quality Enhancement (VQE) algorithms which dramatically improve the quality and clarity of speech communications. The VQE software is available as individual algorithms, or as turnkey solutions for TI processors on many device platforms for a vast range of communication applications.

Doorbell/intercom, hand-held, desktop, wearable communicators all present different challenges and are subject to various noise conditions. Environmental acoustic conditions such as wind, background noise, or reflective surfaces combine with microphone and speaker configurations. Network congestion can cause latency, and packet-loss, further degrading the quality of speech transmission. Echo can completely degrade communication.

Adaptive Digital meets the VQE challenge by delivering fielded, scalable, state-of-the-art voice enhancement algorithms/solutions, flexible configuration options, and real-world experience enabling exceptional voice call performance across each users’ environment.

HD Acoustic Echo Canceller (HD AEC™) algorithm is unparalleled in quality and efficiency. The Multi-Mic Capable, and Full-Duplex HD AEC includes noise reduction, as well as anti-howling, adaptive filtering, nonlinear processing, and double-talk detection. HD AEC provides superior voice clarity and true full duplex performance under a wide set of challenging acoustic environments. It is capable of eliminating the acoustic echo in difficult conditions such as unbalanced speech levels, close speaker to mic proximity, background noise, double talk, echoic reflective room surfaces, and echo path changes.

Noise Reduction algorithm reduces background noise in speech signals under such circumstances where the background sound intensity levels are high. The algorithm can be customized to trade-off between complexity, memory requirements, and required noise reduction.
