He has made significant contributions to the field of voice activity detection and voice quality improvement in packet-based networks. With a total of 4 patents to his name, his work has had a considerable impact on communication technologies.
Latest Patents
One of Anoop's latest patents is titled "Yule walker based low-complexity voice activity detector in noise suppression systems." This invention discloses a low-complexity voice activity detector (VAD) that operates effectively in noisy environments. The VAD computes an occurrence of silent periods within the input signal and utilizes autoregressive (AR) parameters to establish a tentative adaptive threshold. This process allows the VAD to output hypotheses indicating whether speech is present. The VAD also periodically updates its parameters and thresholds to enhance its performance.
Another significant patent is "Speech codec selection for improved voice quality in a packet based network." This method aims to enhance voice quality by matching capabilities between endpoints during an incoming call. It tracks packet loss and negotiates voice quality based on the capabilities of the network. This innovation is crucial for ensuring clear communication in packet-based systems.
