Voice Enhancement

Uses two microphones to create a directional or noise-canceling microphone to adaptively preserve the transmitted voice signal.

Detects wind noise and removes it using sub-band processing.

Digitally increases signal gain (amplification) when the voice signal is weak and conversely compresses the voice signal when it is strong.

Continuously and automatically adjusts sound based on ambient noise level and spectrum.

Detects and attenuates reverberant speech within an audio signal while preserving the direct speech to make it more intelligible using classical signal processing techniques.

Increases the intelligibility of speech by slowing it down dynamically in real time by up to 40% - useful for better comprehension of “fast talkers”, foreign languages, and recorded messages.

Dynamically slows down speech segments in TV sound, making fast speech easier to understand. Video is slowed in parallel, ensuring synchronization of audio and video streams.

Adjusts the dynamic range of an audio signal based on a predefined rule, enhancing soft sounds while maintaining loud ones.

Enhances single-channel speech signals by increasing the signal-to-noise ratio, improving speech intelligibility, and reducing listening fatigue using traditional audio processing techniques.

Enhances single-channel speech signals by increasing the signal-to-noise ratio, improving speech intelligibility, and reducing listening fatigue using neural network processing techniques.

Advanced sound pick-up voice enhancement technology for earbuds (TWS) that utilizes the combination of an internal (in-ear) microphone and external Adaptive Directional Beamforming microphones to robustly discriminate between voice and noise.

Masks the effects of digital voice signal packet loss by reconstructing a synthetic signal to cover missing data.

Detects human speech in an acoustic signal and allows for low-power, always-on voice detection in various devices.

For headphones using four microphone signals (2 on each earcup) to create a voice capture zone, ensuring clear voice transmission even in noisy or windy environments.

Improves speech intelligibility in movies through de-emphasis of overbearing background sounds and music.

Reliably determines the direction of human speech in an acoustic signal in real time.
