Title: Ananth Nagaraja Iyer: Innovator in Automatic Speech Recognition and Audio Fingerprinting
Introduction
Ananth Nagaraja Iyer is a prominent inventor based in Carmel, Indiana, known for his significant contributions to the fields of automatic speech recognition and audio fingerprinting. With a total of 14 patents to his name, Iyer has developed innovative systems and methods that enhance the performance and reliability of audio processing technologies.
Latest Patents
One of Iyer's latest patents is titled "System and method to correct for packet loss in ASR systems." This invention presents a novel approach to correcting packet loss in audio during the recognition stage of automatic speech recognition systems. The method ensures that the ASR engine's behavior remains unchanged in the absence of packet loss, thereby maintaining the integrity of the acoustic models generated during training. The system rectifies the actual input signal, normalizes recognition scores to account for signal errors, and employs a best-estimate method using information from previous frames and acoustic models to replace noisy signals.
Another notable patent is the "System and method for optimization of audio fingerprint search." This invention optimizes the process of searching audio fingerprints by organizing them into a recursive tree structure. The tree branches contain dissimilar fingerprint sets, constructed using a clustering algorithm based on a similarity measure. The recognition process begins at the root of the tree and proceeds down its branches until a match or mismatch is determined, enhancing the efficiency of audio recognition.
