Voice Quality Enhancement

Key Technologies in Consilient's Voice Quality Enhancement Software and Services.

Acoustic Echo Cancellation

Acoustic Echo Cancellation (AEC) software is a core feature of Consilient’s Voice Quality Enhancement package, designed to remove echo in real-time and ensure echo-free, natural conversations. Thanks to the acoustic echo cancellation algorithm's ability to detect and remove echoes, only intended speech is transmitted to the remote end.

Benefits of Acoustic Echo Cancellation Software:

• 

  Improved Voice Call Clarity: The Acoustic Echo Cancellation algorithm effectively eliminates disruptive echoes, ensuring high-quality voice communication with a clear and natural sound.

• 

  Enhanced User Experience in Voice Calls: By removing unwanted echoes, AEC technology significantly reduces listener fatigue, making extended conversations more comfortable and engaging.

• 

  Boosted Productivity through Clear Communication: AEC provides voice quality enhancement in professional settings by enabling echo-free conversations, improving collaboration, and reducing disturbance caused by audio feedback.

Noise Suppression Algorithm

Noise Suppression Software is an essential part of Consilient’s Voice Quality Enhancement suite, engineered to filter out background sounds like traffic, wind, and office chatter. By isolating the speaker’s voice and removing unwanted noise, the Noise Suppression algorithm ensures clear, focused communication — even in the noisiest environments.

Benefits of Noise Suppression Software:

• 

  Clearer Voice Communication in Any Environment: The Noise Suppression algorithm efficiently removes distracting background noises such as traffic, chatter, or wind, ensuring the speaker’s voice remains clear and dominant — a key feature of modern voice quality enhancement systems.

• 

  Versatile Noise Filtering Across Use Cases: Whether you’re on a call on a bustling city street or a noisy office, this advanced background noise reduction technology adapts to your environment, maintaining consistently high audio quality.

• 

  Enhanced Listener Experience with Clean Audio: By reducing ambient sounds and enhancing vocal clarity, Noise Suppression software improves the overall voice call quality, making conversations more enjoyable and professional.

Automatic Gain Control (AGC) and Dynamic Range Compression (DRC) Algorithm

AGC/DRC algorithm provides continuous automatic gain adjustment in the microphone and loudspeaker signals, enhancing perceived audio loudness and ensuring clear intelligibility. Consilient’s AGC algorithm is robust to ambient noises and allows fast signal equalization without increasing ambient noise. The gain changes depending on the amplitude, the limiter level, the compression ratio, and the attack and release time. The gain changes constantly as the audio signal increases and decreases to create the compression effect.

Howling Control Algorithm

Howling can occur in a full-duplex communication link with echo at both ends or coupling paths, creating feedback loops, which can be a severe issue. Howling Algorithm control detects instability as it occurs and takes action to mitigate feedback looping (gain). Consilient’s Howling Control detection algorithm is robust against false detections.

Acoustic Microphone Beamforming Algorithm

Acoustic Microphone Beamforming Algorithm is an advanced technique that uses multiple microphones to capture and isolate the speaker's voice while ignoring surrounding noise. By focusing on the speaker's direction, Acoustic Beamforming Software enhances voice clarity and reduces background interference.

Benefits of Acoustic Beamforming Algorithm:

• 

  Focused Voice Capture: Isolates the speaker's voice, providing clear and precise audio.

• 

  Reduced Background Noise: Minimizes the impact of ambient sounds, improving call quality.

• 

  Enhanced Mobility: The speaker can move freely without affecting voice clarity.
